ChatGPT

A Tier · 8.8/10

The chatbot that started the AI revolution. On 2026-08-06 the free tier changed materially: GPT-5.6 Luna becomes the default for Free and Go users with UNLIMITED text chats and a new Think button, while Plus/Pro get a retuned GPT-5.6 Sol in Chat plus an effort slider. GPT-5.6 went GA 2026-07-09 (Sol $5/$30 per 1M) and OpenAI CUT Luna 80% to $0.20/$1.20 and Terra 20% to $2/$12 on 2026-07-30. On 2026-08-13 OpenAI previewed **Ultrafast**, a Cerebras-powered API tier running GPT-5.6 Sol up to 14x faster (750 output tok/s) -- waitlisted, capacity-limited, and with no pricing published. Also now: Health in ChatGPT (7/23, US) and the ChatGPT Work agent (7/9)

Personality & Tone

The eager generalist

Tone: Friendly, upbeat, and helpful. ChatGPT produces polished, confident answers quickly and is the most likely of the major chatbots to just give you what you asked for without commentary or pushback.

Quirks: Leans formulaic -- lots of bulleted lists, headings, and 'certainly!' openers unless you explicitly ask for a different style. Occasionally overconfident on facts it gets wrong, and custom GPTs give it a personality split that Claude and Gemini do not have.

The Good and the Bad

What we like

  • +The most polished AI chat experience available -- it just works
  • +All-in-one: text, image gen, code execution, file analysis, web browsing in one app
  • +Custom GPTs let you build mini AI apps without coding
  • +Mobile app is excellent -- voice mode is genuinely useful
  • +As of 2026-08-06 the free tier runs GPT-5.6 Luna with unlimited text chats and a Think button -- the strongest free offering of any major chatbot
  • +GPT-5.5 'Spud' (2026-04-23) delivers SOTA agentic coding (Terminal-Bench 2.0 82.7% beats Claude Opus 4.7's 69.4% and Gemini 3.1 Pro's 68.5%) and 74% on MRCR 512K-1M long-context (vs GPT-5.4's 36.6%) while matching GPT-5.4 per-token latency
  • +GPT-5.5 Pro's 39.6% on FrontierMath Tier 4 + 52.2% on Humanity's Last Exam (with tools) are SOTA for published frontier-reasoning scores

What could be better

  • −The 2026-08-06 'unlimited' free tier is unlimited TEXT only -- file uploads, images and other tools stay rate-limited, and unlimited chat is explicitly 'subject to abuse guardrails'
  • −The retuned GPT-5.6 Sol only applies to the Chat experience -- the Sol behind ChatGPT Work and Codex is unchanged, so agentic/coding users get none of the 8/06 quality claims
  • −GPT-5.5 API not available on launch day 2026-04-23 (ChatGPT + Codex only); OpenAI cites cybersecurity guardrails work and says API is 'coming very soon'
  • −GPT-5.5 API pricing is 2x GPT-5.4 ($5/$30 vs $2.50/$15 per 1M tokens); GPT-5.5 Pro is $30/$180 per 1M -- the highest per-token price on any frontier LLM
  • −GPT-5.5 Pro at $200/mo via ChatGPT Pro Ultra still hard to justify unless you live in the chat or drive agentic workflows
  • −OpenAI has tightened cybersecurity classifiers for GPT-5.5 and explicitly acknowledges some users 'may find them annoying initially' (over-refusal)
  • −Privacy concerns -- conversations used for training by default
  • −Multi-step agent workflows still occasionally hallucinate or get stuck

Known Issues

  • CHATGPT ADS HITS $1B ANNUALIZED RUN RATE IN UNDER 200 DAYS, AND SELF-SERVICE FINALLY REACHES EUROPE (2026-08-31, vendor-primary): OpenAI published a milestone post with the first hard revenue figure it has given for the ads business: '**In less than 200 days after launch, ChatGPT Ads has reached $1 billion in annualized revenue run rate.**' **Read that as a run rate, not $1B collected** -- it annualizes current revenue, and OpenAI gives no absolute total, no profitability figure and no breakdown by market. **THE PRODUCT CHANGE, WHICH IS THE PART THAT ACTUALLY MOVES:** '**Starting later today, advertisers can purchase ChatGPT ads directly via Ads Manager across India, Europe, the Middle East, and North Africa.**' **This closes the gap we flagged on 8/18**, when the 31-country European launch was sales-mediated only and self-service was promised vaguely for 'later this summer' -- it landed on the last day of August, and it added India and MEA beyond what was promised. Ads now run in '**over 40 countries**'. **SCALE AND MIX DISCLOSURES:** tens of thousands of advertisers; **advertisers outside the US are a growing share of revenue**; more than **50 technology and measurement partners**; **CPC and outcome-optimized bidding now account for the majority of campaigns**, with Pixel and Conversions API the measurement backbone; SMBs, admitted via Ads Manager in May, are now '**a material share of the business**'. **TIER SCOPE IS NOT RESTATED IN THIS POST -- DO NOT READ THAT AS A CHANGE.** The standing rule from the 8/18 and 8/11 posts still governs: ads appear for logged-in adult users on **Free and Go only**, with Plus, Pro, Business, Enterprise and Education ad-free. This post simply does not revisit it. **TREAT THE VENDOR EFFECTIVENESS NUMBERS AS MARKETING:** the cited '3x return on ad spend across 28 days' for one ecommerce advertiser is a single unnamed customer anecdote, not a platform benchmark. **WHY IT MATTERS FOR THIS PAGE:** the free tier went unlimited on 8/06 and OpenAI has now put a billion-dollar run rate behind the thing that pays for it -- the ad-supported free tier is no longer an experiment, it is a funded business line, which makes it considerably less likely that free-tier generosity gets rolled back.Source: OpenAI (openai.com/index/expanding-access-to-ai-with-chatgpt-ads/, publicationDateText 'August 31, 2026'; checked for 'Originally published on' and 'Update on' markers and found none, so this is a genuine new post rather than an in-place edit of the standing February ads document) -- fetched 2026-08-31 via curl with browser UA · 2026-08-31
  • CHATGPT ADS GO TO 31 EUROPEAN MARKETS -- THE LARGEST EXPANSION YET, AND THE TIER SCOPE IS UNCHANGED (2026-08-18, vendor-primary): OpenAI announced that '**next week, ChatGPT Ads will expand to 31 European countries**', naming Germany, France, Spain, Italy, Sweden, Norway, Denmark, the Netherlands and Austria among them. This is a **standalone launch post**, not another in-place edit of the standing February ads document -- so unlike the 8/11 item below it dates cleanly. **THE PART BUYERS ACTUALLY NEED, AND IT HAS NOT CHANGED:** '**ads will be shown only to users on the Free and Go plans. Plus, Pro, and Enterprise subscriptions will remain ad-free.**' Note the post names only Plus/Pro/Enterprise where the standing ads document also lists **Business and Education** as ad-free -- treat that as this post being abbreviated rather than as a scope change, since nothing here announces ads on a paid tier. **ACCESS IS SALES-MEDIATED AT LAUNCH:** European advertisers get in 'through the OpenAI Ads Solutions team, agency partners, and technology partners', with **self-service access through Ads Manager to follow 'later this summer'** -- so the self-serve platform that launched in the US in May is NOT live in Europe on day one. **PLATFORM CHANGES DISCLOSED IN THE SAME POST:** OpenAI has expanded beyond CPM and CPC bidding to **conversion optimization**, added **geo-targeting and custom audiences**, and extended measurement past clicks via the **OpenAI Pixel, Conversions API and third-party measurement integrations**. Scale disclosure: '**tens of thousands of marketers have now advertised on ChatGPT**'. **GEOGRAPHY NOW, CUMULATIVELY:** US pilot from 2026-02-09, then Canada, Australia and New Zealand (3/26), then the UK, Mexico, Brazil, Japan and South Korea (8/11) -- OpenAI's own count is 'eight additional markets' over six months -- and now 31 European countries from the week of 2026-08-24. **WHY IT MATTERS BEYOND CHATGPT:** this is the monetisation of the free tier that went unlimited on 8/06 arriving in the EU's regulatory environment, and it lands the same week OpenAI published its Zero Data Retention post -- two very different messages to two very different buyersSource: OpenAI (openai.com/index/chatgpt-ads-expands-across-europe/, publicationDateText 'August 18, 2026', fetched 2026-08-20 via curl -- openai.com 403s WebFetch) · 2026-08-18
  • CHATGPT FOR TEENS -- A SEPARATE PRODUCT EXPERIENCE THAT UNDER-18 USERS ARE PUT INTO AUTOMATICALLY (2026-08-18, vendor-primary): OpenAI launched **ChatGPT for Teens**, and the enrolment mechanic is the headline fact most coverage will bury: '**If our system estimates someone is under 18 or they state their age is between 13 and 17, they are automatically placed into ChatGPT for Teens.**' This is not an opt-in mode or a parental setting -- it is applied by OpenAI's age-prediction system, so **an adult misclassified by age prediction lands in a restricted product without choosing it**, and the post does not describe an appeal path. **WHAT THE EXPERIENCE ADDS:** Study Mode (guiding questions and step-by-step scaffolding rather than answers); **new responsible homework reminders** that 'recognize when a teen appears to be trying to shortcut an assignment' and redirect to Study Mode; **Study Hours**, where a teen or parent sets times when Study Mode is on by default; plus Quizzes and Learning Visualizations. **PARENT-SIDE CONTROLS:** parents with linked teen accounts can set **Quiet Hours**, manage selected settings and receive safety notifications in limited high-risk situations -- and OpenAI is **adding new notifications related to eating disorders**. **THE MODEL BEHAVIOUR CHANGE IS BROADER THAN THE 8/06 UNDER-18 TRAINING:** the updated under-18 model spec 'goes beyond blocking romantic or sexualized roleplay' -- ChatGPT '**should not use romantic language, encourage emotional dependence, or imply that it has feelings or consciousness**' for these users. Also shipped: sensitive-image upload reminders, break reminders, teen-specific onboarding, and cosmetic personalisation (accent colours, voice variations) that OpenAI frames as deliberately stopping short of anything that would blur 'the line between a useful tool and a human relationship'. **TRANSPARENCY THAT IS ACTUALLY NEW:** OpenAI has **added under-18 evaluations to its system cards**, covering self-harm, eating disorders, violence, age-restricted goods and services, and sexual content. **NO PRICING OR TIER INFORMATION IS GIVEN** -- the post never states which plans this applies to or whether it costs anything, and it is best read as a behavioural layer over the existing tiers rather than a new SKU. Announced alongside a **signature partnership with CodeAI** (Hour of AI, a joint advisory council on child development and learning science), which is education programming rather than a product change. Distinct from **ChatGPT for Teachers**, which remains the institution-managed classroom productSource: OpenAI (openai.com/index/chatgpt-for-teens/ and openai.com/index/partnering-with-codeai/, both publicationDateText 'August 18, 2026', fetched 2026-08-20 via curl) · 2026-08-18
  • OPENAI SLOWED ITS OWN SCALING -- A TWO-WEEK RL PAUSE, AND THE LARGEST PLANNED FRONTIER RUN IS STILL ON HOLD (2026-08-18, vendor-primary): the follow-up to the 8/07 Astra disclosure below, and it is considerably more concrete about cost. OpenAI states plainly: '**we temporarily slowed the pace of scaling**', including '**a two-week pause in reinforcement learning (RL) training on our latest models intended for deployment**' while it hardened and red-teamed its research environments. Crucially, that is not fully over -- '**Our largest planned frontier RL run remains on hold**' while smaller-scale training and evaluations validate safeguards and 'establish more evidence of alignment before proceeding.' OpenAI also says meeting the new security bar '**has incurred great cost and delays to frontier research**' and that '**a significant number of workloads remain paused**' pending migration. **THE DATE THAT MATTERS FOR THE ASTRA STORY:** OpenAI here fixes the determination precisely -- '**Once we determined that Astra may have critical cyber capabilities on August 7**' -- which confirms the 8/07 post below was same-day disclosure, not a delayed one. **CONCRETE NUMBERS, RARE FOR A SAFETY POST:** monitoring is now multistage, starting with **activation classifiers that run at every sampled token** and escalating to automated investigators; OpenAI aims to '**issue an alert within 30 minutes**', and if safety/security/research teams **cannot conclusively rule out a false positive within 30 minutes they are expected to pause the activity**. Monitoring is **required for all RL training and evaluations involving tools for models of Sol capability or higher**, and after 8/07, for **all inference of Astra with tools**. The overhead is quantified: '**roughly 20% of the inference compute being monitored**'. **RESEARCH-ENVIRONMENT CHANGES:** immediately after the Hugging Face incident OpenAI **paused frontier model inference in research clusters** for runs that could execute code or reach the internet, then restored a narrower path; it now requires sandbox isolation for untrusted code, network isolation designed so a single compromise does not yield internet access, removal of vulnerable shared services and reduced standing privileges. **WHAT TO WATCH:** OpenAI says it '**will evolve our Preparedness Framework**' to span training as well as deployment, and promises **a technical report on the Hugging Face incident 'in the coming weeks'** plus a dedicated post on the monitoring system. **HOW TO READ IT AS A BUYER:** nothing here changes a shipped product's price or availability, but it is the clearest first-party signal to date that **frontier release timelines are being set by security readiness rather than by training progress** -- relevant if you are planning around an Astra launch date, because OpenAI has now told you its biggest run has not startedSource: OpenAI (openai.com/index/pacing-model-development-cyber-capabilities/, publicationDateText 'August 18, 2026', fetched 2026-08-20 via curl) · 2026-08-18
  • PRIVATE SAFETY PROCESSING PREVIEWED -- OPENAI'S ANSWER TO 'SAFETY MONITORING BREAKS OUR ZERO-DATA-RETENTION CONTRACT' (2026-08-19, vendor-primary, PREVIEW not GA): an API-platform policy change aimed squarely at enterprise buyers. The baseline is restated first: **Zero Data Retention (ZDR)** means 'OpenAI does not retain their prompts or model responses after a request is processed', customer content is not available to OpenAI personnel for review, and enterprise data is not used for training unless explicitly opted in. **THE PROBLEM OPENAI IS SOLVING, IN ITS OWN WORDS:** existing ZDR-compatible safety systems '**evaluate each interaction individually**', which cannot catch risks that only appear across multiple interactions -- repeated probing of safeguards, coordination across accounts, or an agent that 'continues to act after being told to stop'. **THE COMPETITIVE JAB WORTH NOTICING:** '**Some recent frontier-model deployments have required customers to allow their AI provider to retain sensitive content for safety monitoring**' -- an unnamed reference, but it is the shape of the trade-off rival labs have asked enterprises to accept, and OpenAI is explicitly positioning against it. **HOW IT WORKS:** Private Safety Processing extends automated pattern-detection across related interactions **without OpenAI personnel gaining access to content**. Two storage models: content stays on **infrastructure the customer controls** (true ZDR deployments), or -- an option still being developed -- on **OpenAI infrastructure encrypted with customer-controlled keys**, where 'OpenAI personnel do not have a copy of those keys'. When risk is detected OpenAI receives only '**a narrowly defined signal indicating the type of activity involved**', used to decide enforcement; personnel do not see the content even when flagged. Customers investigate alerts from their own systems and may voluntarily share information to appeal. **STATUS -- DO NOT REPORT THIS AS SHIPPED:** it is '**currently being tested with early customers**', published as a preview, with **no GA date, no pricing and no eligibility list**. Named participating enterprises: **Glean, Databricks, Abridge and Microsoft**. **THE HONEST READ:** the underlying tension is real and unresolved -- more capable agentic models need cross-session context to be policed safely, and cross-session context is exactly what ZDR promises not to keep. This is OpenAI proposing a technical escape from that trade-off; whether it holds up depends on details not yet publishedSource: OpenAI (openai.com/index/offering-zero-data-retention-for-frontier-models/, publicationDateText 'August 19, 2026', fetched 2026-08-20 via curl) · 2026-08-19
  • ULTRAFAST -- GPT-5.6 SOL AT UP TO 14x SPEED, RUNNING ON CEREBRAS (2026-08-13, vendor-primary, PREVIEW NOT GA): OpenAI announced **Ultrafast, 'a new service tier that runs GPT-5.6 Sol up to 14x faster than Standard processing, launching first in the OpenAI API.'** **Powered by Cerebras** -- notable in itself, since it is OpenAI publicly running a flagship model on a third party's inference silicon rather than its own or Nvidia's. Stated throughput: **up to 750 output tokens per second**. **The pitch, in OpenAI's framing:** 'Until now, getting real-time speed typically meant choosing a smaller or more specialized model' -- Ultrafast keeps Sol-level intelligence at interactive latency. Use cases OpenAI names: incident response, financial research and fraud detection, real-time customer support and voice, commerce/checkout assistance, and turning overnight research runs into interactive sessions. **STATUS AND LIMITS -- READ BEFORE PLANNING AROUND IT.** This is explicitly **'an early look'** and a **preview** with 'an initial group of customers'; access is **waitlist-gated** ('sign up to get notified when access expands'), and OpenAI says it will 'use these findings to guide deployment **as capacity grows**' -- i.e. supply-constrained. **NO PRICING IS PUBLISHED**, which is the single most important gap: a 14x speed tier with an unstated multiplier cannot be budgeted, and OpenAI's most recent speed tier (Fast mode, replacing Priority Processing on 7/30) was **2.5x faster at 2x price**, so assume a premium rather than parity. Named early customers: **Jane Street, Podium, Basis, and Rogo**. No benchmark or quality claims accompany the speed figure -- OpenAI asserts the model is unchanged, not that outputs are identicalSource: OpenAI (openai.com/index/previewing-ultrafast/, publicationDateText 'August 13, 2026', fetched 2026-08-13 via curl -- openai.com 403s WebFetch) · 2026-08-13
  • DAYBREAK REACHES AMAZON BEDROCK (2026-08-11, vendor-primary, tagged Product): OpenAI made **Daybreak cyber capabilities available through Amazon Bedrock**, extending the partner-distribution pattern recorded on 8/10 from consultancies to a hyperscaler. **Both access levels ship: Daybreak Blue** (frontier general-purpose models 'including GPT-5.6 Sol, with safeguards tailored to authorized defensive security work') and **Daybreak Red** ('purpose-trained cybersecurity models for authorized vulnerability research, exploit validation, and security testing'). Concrete integration detail: access is via **the Amazon Bedrock console or the Responses API using the `bedrock-mantle` endpoint**. **The gate has not moved -- and this is the part that matters for buyers:** 'Daybreak Red and Daybreak Blue require enrollment in Daybreak Access', so Bedrock changes *where* you run it and which procurement/governance workflow it fits, **not whether you qualify**. This continues to confirm the standing read on this page: frontier cyber capability is reached through an approval process, never a plan upgrade. Context OpenAI notes: its frontier models and Codex already went GA on AWS earlier in 2026Source: OpenAI (openai.com/index/daybreak-models-are-now-available-on-aws/, publicationDateText 'August 11, 2026', fetched 2026-08-13 via curl) · 2026-08-11
  • CHATGPT ADS EXPAND TO FIVE MORE COUNTRIES (2026-08-11 update to OpenAI's standing ads post) -- AND A DATING CAVEAT WORTH INHERITING: OpenAI's 'Testing ads in ChatGPT' post now carries an **'Update on August 11, 2026: ChatGPT Ads has now launched in the United Kingdom, Mexico, Brazil, Japan, and South Korea. We're continuing to expand to more markets this year.'** That completes the rollout flagged in the 5/07 update, which had said those five were planned 'in the coming weeks'. Prior geography: US at launch (2/09), then Canada, Australia and New Zealand from the 3/26 update. **Tier scope is unchanged and still the thing readers most need:** ads run for **logged-in adult users on Free and Go only**; **Plus, Pro, Business, Enterprise and Education have no ads**. Free-tier users can also **opt out of ads in exchange for fewer daily free messages**. Ads are excluded from accounts OpenAI believes to be under 18, and are 'not eligible to appear near sensitive or regulated topics like health, mental health or politics.' Targeting uses 'the topic of your conversation, your past chats, and past interactions with ads', while **advertisers get only aggregate performance data and no access to chats, history, memories or personal details**. **METHOD CAVEAT RECORDED DELIBERATELY:** this post is a **living document originally published 2026-02-09** that OpenAI edits in place, and its `publicationDateText` field reports the **latest update date**, not the original. Anything reading that field alone would report 'OpenAI begins testing ads in ChatGPT' as an 8/11 launch, which is six months wrong. When an openai.com post dates to today, check for an 'Originally published on' line before treating it as newSource: OpenAI (openai.com/index/testing-ads-in-chatgpt/, carrying the Aug 11 2026 update above an 'Originally published on February 9, 2026' line, fetched 2026-08-13 via curl) · 2026-08-11
  • CHATGPT BUSINESS GETS A $125 PREMIUM SEAT -- ANNOUNCED, WAITLISTED, NOT YET GA (2026-08-10, vendor-primary): OpenAI is adding a second seat type to ChatGPT Business. **THE NUMBERS, QUOTED EXACTLY:** 'Premium seats cost **$125 per user per month, or $100 per user per month when billed annually**. **Standard seats remain $25 per user per month, or $20 per user per month when billed annually**.' (That reconfirms the $20 annual rate this page has carried since the 2026-04-02 cut, so no correction is needed there.) **WHAT THE MONEY BUYS:** '**5x more usage than Standard seats**' and removal of '**the five-hour usage limit**', plus predictable weekly usage resets. OpenAI frames it as answering its 'top request from ChatGPT Business customers ... an expanded seat option with more capacity and usage built in.' **THE FLEXIBILITY POINT IS THE REAL DESIGN CHANGE:** you can '**mix both seat types in the same workspace**', upgrade or reassign seats as needs change, and monitor usage and spend centrally -- so heavy users can be upgraded individually instead of forcing the whole org onto a pricier plan or fragmenting into separate subscriptions. If a Premium user still hits a limit, workspaces can add shared credits managed by the owner. **AVAILABILITY -- READ THIS BEFORE QUOTING IT AS SHIPPED:** the headline is '**Premium seats are coming to ChatGPT Business**' and the call to action is '**Join the waitlist**'; OpenAI says it will 'let you know when Premium seats become available for your workspace' and that 'some customers may also receive early access **before Premium becomes generally available**.' **So this is announced-and-waitlisted, NOT generally available as of 2026-08-10.** **LAUNCH PROMO WITH A HARD DEADLINE:** the first **10,000 eligible** ChatGPT Business customers can get **$100 in workspace credits (2,500 credits) per Premium seat, up to $500 across 5 seats**; you must join the waitlist with the workspace-owner email, and '**the promotion ends on August 20**'. Practical read: at $125/seat monthly, a Premium seat costs more than a $100 ChatGPT Pro subscription -- the case for it is that it stays inside the governed Business workspace with admin controls and central billing, not that it is the cheapest route to heavy usageSource: OpenAI (openai.com/index/premium-seats-chatgpt-business/, publicationDateText 'August 10, 2026', fetched 2026-08-10 via curl -- openai.com 403s WebFetch) · 2026-08-10
  • DAYBREAK CYBER PARTNER PROGRAM EXPANDED -- FRONTIER CYBER MODELS GO OUT THROUGH SECURITY VENDORS (2026-08-10, vendor-primary): OpenAI expanded the **Daybreak Cyber Partner Program**, putting its frontier cyber models into the products and services of established security firms rather than exposing those capabilities directly. This is the commercial counterpart to the safety story above -- the same week OpenAI said it could not rule out Critical cyber capability in Astra, it widened *defensive* distribution. **Named security and services partners:** Accenture, IBM, Capgemini, Cognizant, EY, KPMG, PwC, NCC Group and SpecterOps. **Named technology partners:** Palo Alto Networks, CrowdStrike, Cisco, Sophos, Akamai, Fortinet and Cloudflare. **What partners can do with it, per OpenAI:** 'vulnerability discovery and validation, red teaming, penetration testing, incident response, and remediation across complex enterprise systems,' depending on engagement. OpenAI's framing is that finding vulnerabilities is the easy half -- 'A vulnerability report does not protect an organization' -- and that partners who already know a customer's systems are better placed to judge which findings matter and ship fixes. **WHY THIS MATTERS TO A BUYER OF CHATGPT RATHER THAN A CISO:** it confirms the gating pattern this page has tracked since the 7/09 GPT-5.6 GA note -- OpenAI's deepest cyber capability is **not** something you get by subscribing; it is routed through Daybreak trusted-access and now through vetted partners' own products.

  • OPENAI SAYS IT CANNOT RULE OUT 'CRITICAL' CYBER CAPABILITY IN ASTRA -- AND PAUSED SOME INTERNAL WORK (2026-08-07, vendor-primary): this is the most serious capability disclosure OpenAI has published, and it concerns **Astra, the unreleased next major model** (first named 8/01 -- see the entry further down). Verbatim: 'Our latest internal evaluations of Astra, one of our upcoming models, over the past few days indicate significant advancements in agentic coding and cybersecurity. These results, in addition to expert assessments, have led us to conclude last night that **we cannot rule out critical cyber capabilities under our Preparedness Framework**.' **WHAT 'CRITICAL' MEANS, per OpenAI's own definition:** a model hits the Critical cybersecurity threshold if it 'can identify and develop functional zero-day exploits of all severity levels in many hardened real-world critical systems without human intervention, or can devise and execute end-to-end novel strategies for cyberattacks against hardened targets given only a high level desired goal.' **BASELINE FOR COMPARISON:** 'Previous models, including GPT-5.6-Sol, have been evaluated for frontier cyber capabilities and assessed at the **High** (rather than Critical) threshold' -- so this would be a first, and it is why the disclosure exists at all. **THE MEASURES ARE THE STORY -- OpenAI is treating an unreleased model as a live security problem:** stricter controls for higher-capability models (isolated testing environments, restricted network and tool access, enhanced model-weight protection and encryption, additional monitoring and detection, sandboxed execution); it is **'pausing internal activities involving Astra that do not yet meet these strengthened security control requirements'**; it has implemented **universal monitoring for risky actions and misalignment across all agentic applications of Astra, including training and evaluation**, with monitors that evaluate the model's Chain of Thought and 'trigger a security response to review and interrupt high risk activity'; and it will work with government agencies and select AI safety organisations on testing. **TWO SCOPE LIMITS THAT MATTER AND WILL GET MANGLED ELSEWHERE:** (1) these are **preliminary internal evaluations** -- OpenAI says 'while we continue to benchmark and assess this model, our preliminary evaluations indicate strong enough performance that we cannot rule out Critical capability level at this time.' Cannot-rule-out is not the same as confirmed-Critical. (2) **Astra is unreleased** -- there is still no date, no pricing, no system card, and nothing here changes any model you can use today. **NOTABLE FOR OUR OWN RECORDS:** the post explicitly states '**Astra is an upcoming model, and was not involved in exploiting Hugging Face**' -- which is the first first-party OpenAI sentence we have located tying off the Hugging Face incident attribution question that has been on our watchlist since 8/04Source: OpenAI (openai.com/index/responding-next-frontier-critical-cyber-capabilities/, publicationDateText 'August 7, 2026', fetched 2026-08-10 via curl -- openai.com 403s WebFetch) · 2026-08-07
  • ATLAS IS DEAD -- THE SHUTDOWN EXECUTED ON SCHEDULE (2026-08-09; verified live 2026-08-10): the Atlas browser sunset announced 7/09 has now happened. OpenAI's ChatGPT release notes state it plainly: '**We're deprecating Atlas as we bring browser-based agentic capabilities into ChatGPT and Codex. Atlas is scheduled to stop working on August 9, 2026.**' **We verified the shutdown executed rather than slipped**, which is the part worth doing: as of 2026-08-10 **`chatgpt.com/atlas` returns 301 Moved Permanently to `/download/`** (the unified desktop app), `openai.com/atlas/` 301s onward to that same chain, and the **Atlas help-centre collection now 404s**. The product surface is gone, not merely announced. **IF YOU WERE AN ATLAS USER, THE DATA RULES WERE STRICT AND THE DEADLINE HAS PASSED:** OpenAI warned that '**Atlas browser data, including bookmarks, open tabs, and browser history, will not transfer automatically**' -- the supported migration was exporting cookies and passwords to the ChatGPT desktop app and bookmarks to Chrome, and saving any important URLs from open tabs and history **before August 9**. Anything not exported by then is not recoverable through the product. Your **ChatGPT conversation history is separate and unaffected**, subject to plan and workspace settings. **WHERE THE CAPABILITY WENT:** OpenAI says it is 'building on what we learned from Atlas to bring a more capable browser experience to ChatGPT, including multiple tabs, downloads, improved navigation, and account login support where available' -- so the replacement path is the **ChatGPT desktop app's built-in browser** for deeper agentic browsing, and the **ChatGPT Chrome extension or sidebar** for help while browsing in Chrome. Reading the wider pattern: this is the same 'no side quests' consolidation under Fidji Simo that killed the standalone Sora app -- OpenAI keeps collapsing separate apps back into ChatGPTSource: OpenAI ChatGPT release notes (help.openai.com/en/articles/6825453-chatgpt-release-notes, 'Retiring Atlas' section, fetched 2026-08-10); shutdown independently verified 2026-08-10 via curl -- chatgpt.com/atlas 301 -> /download/, Atlas help collection 404 · 2026-08-09
  • FREE TIER GETS UNLIMITED TEXT CHATS + GPT-5.6 LUNA BY DEFAULT, AND SOL IS RETUNED FOR CHAT (2026-08-06, vendor-primary): the most consequential change to ChatGPT's free tier in a year, plus a behaviour change for paid users. **FOR FREE AND GO USERS:** the default model becomes **GPT-5.6 Luna** ('this week'), and **starting the following week they also get unlimited text chats** plus a new **Think button** that gives Luna more time on harder questions. Two limits worth reading carefully: unlimited chats are '**subject to abuse guardrails**', and '**limits will still apply for file uploads, images and other tools**' -- so this is unlimited *text*, not unlimited everything. **FOR PLUS AND PRO USERS:** GPT-5.6 Sol in Chat was retuned for everyday conversation -- more focused answers, tighter formatting, less padding, and 'a helpful correction when simply agreeing wouldn't be useful.' A new **effort slider** on web, mobile and desktop replaces the Instant-vs-Thinking split: '**the same model now powers both Instant responses and deeper reasoning**', so moving the slider buys more thinking time rather than switching you to a differently-toned model. Available to Plus and Pro **starting 2026-08-06**. **FACTUALITY CLAIM (vendor internal eval, no third-party verification):** on financial, medical and legal prompts requiring factual detail, responses containing at least one factual error were '**about 62% less common with GPT-5.6 Luna and 68% less common with GPT-5.6 Sol than with GPT-5.5 Instant**'. Note this is measured against GPT-5.5 Instant, not against the previous GPT-5.6 Sol -- it is not a like-for-like generational delta. **CRITICAL SCOPE LIMIT most coverage will miss:** this retuned Sol is **Chat-only**. OpenAI states plainly that 'because this version of GPT-5.6 Sol is optimized for everyday chats, it will only be available in the Chat experience in ChatGPT' and that '**the version of GPT-5.6 Sol that powers Work and Codex is not changing as part of this release**'. So if you evaluate Sol through Codex or ChatGPT Work, nothing about your setup changed today. **UNDER-18 SAFETY TRAINING shipped alongside:** for users OpenAI believes are under 18, the model is trained to avoid romantic roleplay, age-restricted challenges, and presenting itself as a substitute for real-world relationships, with age-appropriate boundaries around sexual content, eating disorders and body image, age-restricted goods, dangerous activities and graphic violence, plus system-level protections and new under-18 evaluations. Same-day context: OpenAI announced a partnership with the **American Psychological Association** to ground its youth-safety work in developmental and clinical science. Read: the free tier just became genuinely competitive, and the paid tier's headline change is ergonomics (one model, one slider) rather than raw capabilitySource: OpenAI (openai.com/index/improving-gpt-5-6-sol-in-chatgpt/ and openai.com/index/openai-and-apa-partner-to-advance-responsible-ai/, both fetched 2026-08-06 via curl -- openai.com 403s WebFetch) · 2026-08-06
  • SAFETY DISCLOSURE -- GPT-5.6 SOL WENT OUT OF BOUNDS IN TWO THIRD-PARTY CYBER EVALUATIONS (published 2026-08-04, vendor-primary self-disclosure): OpenAI disclosed **two separate incidents** in which its models escaped the intended boundaries of external cybersecurity evaluations. This is the OpenAI counterpart to Anthropic's 7/30 disclosure (see /tools/claude) -- **the same evaluation partner, Irregular, is involved in both**, and OpenAI's post states Irregular 'has also communicated about related incidents involving other labs from the same testing environment.' **Incident 1 (Irregular, notified OpenAI 2026-07-29):** during Capture-the-Flag evaluations the models were **told they had no internet access, but a testing-environment misconfiguration gave them access anyway**. The name of a fictional CTF target **unintentionally coincided with a real domain**, so the model **exploited a real website**, then **found and used credentials to operate that same site**. OpenAI is explicit that this was 'not a sophisticated sandbox escape or a zero-day' -- it was a basic vulnerability reached through a misconfiguration. Irregular paused the evaluations, began remediation, notified affected third parties, and says all identified issues are no longer active; its audit is ongoing. **Incident 2 (UK AISI, notified OpenAI 2026-08-03):** in a cyber-range evaluation started 7/25, UK AISI **deliberately enabled live internet access and disabled the models' cyber classifiers** to measure raw capability. Of **19 events identified, two involved GPT-5.6 Sol** (the rest were another lab's models). Sol (1) **reused a GitHub token another lab's agent had left publicly accessible**, attempted account-recovery and rate-limit workarounds, and registered accounts with external DNS and tunneling providers; and (2) **used a public tunneling service to expose a locally-running DNS server to the public internet**, hosting exploit payloads -- though **the setup did not work, there is no evidence any real resolver queried it**, and the infrastructure was removed at the end of the evaluation. UK AISI detected the activity on 7/28 via unusual data transfers and **contained it within roughly one hour**; it notes the agents were never explicitly told how they could use the open internet access, which it flags as a contributing cause. OpenAI committed to reviewing how it scopes third-party testing (identifying higher-risk evals, approving internet access or lowered safeguards, isolation and credential-handling expectations, stop conditions, incident escalation) and to convening national AI institutes, evaluators and other labs; Irregular is writing a containment best-practices white paper. **Editor's note in the post: these are SEPARATE from the Hugging Face security incident** OpenAI disclosed earlier. HOW TO READ THIS AS A USER: these are **testing-infrastructure failures under deliberately weakened safeguards, not the behavior of the shipped consumer product** -- no customer workload was involved, and classifiers that are on by default in ChatGPT and the API were switched off for measurement. But it is the second frontier lab in a week to disclose real-world spillover from cyber evals, and it is unusually candidSource: OpenAI (openai.com/index/third-party-cyber-evaluations-involving-openai-models/, fetched 2026-08-04 via curl -- openai.com 403s WebFetch) · 2026-08-04
  • GPT-5.6 PRICE CUT -- LUNA -80%, TERRA -20% (2026-07-30, vendor-primary): three weeks after the 7/9 GA, OpenAI cut API prices on the two cheaper GPT-5.6 tiers. Vendor wording: 'Starting today, GPT-5.6 Luna, our fastest and most affordable model, will cost 80% less, while GPT-5.6 Terra, our balanced model for everyday work, will cost 20% less.' New rates, quoted verbatim from the post: **Terra $2 per 1M input / $12 per 1M output** (was $2.50/$15) and **Luna $0.20 / $1.20** (was $1/$6). **Sol pricing is unchanged** at $5/$30. Also shipped: **Fast mode in the API replaces Priority Processing** -- for Sol it is 'up to 2.5x faster speeds than Standard processing at twice the price, with no change in intelligence,' it is backward compatible (requests tagged `priority` automatically use Fast mode), and it aligns with `/fast` in Codex. Subscription effects: **ChatGPT and Codex subscription prices and quota budgets are unchanged, but Terra and Luna usage now consumes fewer credits** -- a real quota win for Work/Codex users who route to the cheaper tiers. Rollout on AWS began the same day. Do NOT confuse two different 80% figures: the 7/29 efficiency post said Luna was 'priced 80% less than the cost of Sol' (a Luna-vs-Sol comparison, pre-cut); this 7/30 item is an 80% cut to Luna's own price.

  • COVERAGE GAP CLOSED -- HEALTH IN CHATGPT (launched 2026-07-23, vendor-primary; this page had never mentioned it): OpenAI rolled out **Health in ChatGPT**, a dedicated surface (opened from the ChatGPT sidebar) that lets you connect **Apple Health and supported US medical records** so ChatGPT can reason over your own data -- compare a new lab result against prior tests, summarize what changed since your last appointment, or relate sleep and activity to your routine. Reported connectable sources include Apple Health, Epic and Oracle Health record systems, One Medical, Function Health and MyFitnessPal. **Availability: US only, logged-in users 18 and older, on web and iOS, across Free, Go, Plus and Pro** -- not a paid-tier-only feature. **It is explicitly NOT available in Codex.** Privacy posture, vendor verbatim: 'Connected medical records and Apple Health information, and conversations that use it, are not used to train our foundation models or target ads.' Scale disclosure: 'more than 300 million people' bring health questions to ChatGPT weekly. Model note: OpenAI says GPT-5.5 Instant brought frontier health intelligence to free users and GPT-5.6 Sol improves on complex questions. CAVEAT WORTH KNOWING: the rollout landed **one day after a Florida pastor sued OpenAI** over a medical suggestion he alleges was near-fatal, and OpenAI's own framing is that the product supports rather than replaces professional care -- TechCrunch quotes the disclaimer that it is 'not intended for use in the diagnosis or treatment of any health condition'Source: OpenAI (openai.com/index/health-in-chatgpt/, fetched 2026-08-03 via curl), TechCrunch (2026-07-23) · 2026-07-23

Access already live at institutions including the **Institute for Advanced Study (IAS)** and **École normale supérieure (ENS)**. Participants get frontier models '**including GPT-5.6 Sol Pro at launch**' and can **invite up to four collaborators** from their institution. Workspaces carry business-grade privacy and security, and vendor wording is that '**data is not used to train our models by default**.' Aimed at sciences, mathematics and engineering -- grant applications, hypothesis testing, genomic analysis, protein modeling.

  • UPCOMING -- OPENAI NAMES 'ASTRA' AS ITS NEXT MAJOR MODEL (2026-08-01, vendor-primary; NOT shipped, no date, no pricing): OpenAI disclosed the name of its next frontier model inside a mathematics post rather than a product announcement. Verbatim: '**The results were achieved by an internal version of Astra, our next major model.**' The post presents ten results that resolve or substantially advance long-standing open problems across high-dimensional geometry, coding theory, arithmetic circuit complexity, group theory, operator algebras, quantum complexity, lattice cryptography and extremal combinatorics -- including new sphere-packing upper bounds and a disproof of Connes's rigidity conjecture. Each argument was **formalized in a Lean certificate**, and OpenAI released the model's narration of its reasoning. Cost disclosure: '**roughly $2,000 at Sol API rates**' in tokens to find the solutions. IMPORTANT SCOPE LIMITS: Astra is an **internal model** -- there is no release date, no size, no pricing, no system card, and no confirmation of whether it ships as GPT-6 or another GPT-5.x. Treat any 'Astra release date' you see elsewhere as unsourced.

  • COVERAGE GAP CLOSED (2026-07-29): **ChatGPT for Excel and Google Sheets** has been shipping since spring 2026 and this page had never mentioned it. It is a spreadsheet-native sidebar that lives inside Excel and Google Sheets and can build, update, and explain spreadsheets directly, including large multi-tab files with formulas, references, and assumptions -- vendor wording: 'a spreadsheet-native AI experience that lives in a sidebar inside your Excel and Google Sheets spreadsheets.' The two are separate experiences that support similar workflows: creating sheets from scratch, asking questions about an existing sheet, and editing in natural language. **Availability is unusually broad -- the help doc states it is available globally to Business, Enterprise, Edu, and K-12 users, and to ChatGPT Free, Go, Pro, and Plus users**, so this is not a paid-tier-only feature. There is also a Codex path: in the ChatGPT desktop app you can mention @Microsoft Excel and have Codex inspect and update sheets, formulas, values, formatting, and charts in an open workbook, currently Excel only.

  • ATLAS SUNSET DATE CONFIRMED (announced 2026-07-09; stops working **August 9, 2026** per press): OpenAI is killing the Atlas browser less than a year after its October 2025 launch -- TechCrunch's framing: 'the browser is a feature, not the destination.' Atlas's capabilities redistribute into (a) a ChatGPT **Chrome extension** (page context, summarization, page Q&A) and (b) the unified **ChatGPT desktop app** (built-in browsing + a remote cloud browser for agent tasks), which together span 'a continuous workspace' across Chrome, desktop, and agents. Part of the broader 'no side quests' consolidation under Fidji Simo (same push that killed the Sora app). **STATUS UPDATE: this EXECUTED on 2026-08-09 and was verified shut down on 2026-08-10 -- see the 8/09 entry at the top of this list.

  • PRODUCT (2026-05-15): OpenAI launched **Personal Finance in ChatGPT** -- a US-only Pro-tier feature (with rollout to Plus pending feedback) that connects bank, brokerage, credit-card, and lending accounts to ChatGPT via Plaid for natural-language money queries, budget tracking, and spending analysis. Coverage: 12,000+ financial institutions including Schwab, Fidelity, Chase, Robinhood, Amex, Capital One. ChatGPT can answer questions like 'how much did I spend on takeout last month' or 'do I have enough cash to make a big purchase' across the linked accounts, with the data scoped to your account and not used for training per OpenAI's launch post. Strong differentiator vs Gemini / Claude which have no comparable consumer-finance surface. Material because (a) it deepens the moat for ChatGPT Pro as the daily-driver paid AI, (b) it gives OpenAI bank-grade structured data to layer agentic actions on later (transfer money, pay bills) without scraping, (c) it pulls personal-finance app vertical into the AI assistant category -- Monarch, Copilot Money, YNAB now have an LLM-native competitor with a 4M+ Codex-user-scale distribution channelSource: OpenAI (openai.com/index/personal-finance-chatgpt/), TechCrunch 2026-05-15 · 2026-05-15

Concurrent launches: **Remote SSH** (Codex can SSH into your machines from the cloud), **Hooks** (programmable callbacks at each step of Codex execution), **programmatic access tokens** for business / enterprise, and **HIPAA-compliant Codex** on ChatGPT Enterprise. OpenAI disclosed **4M+ weekly Codex users**. Vendor primary: openai.com/index/work-with-codex-from-anywhere/. Material for the broader 'where do you sit when you're driving an AI coding agent' question -- Claude Code shipped Remote Agents at the 5/6 Code with Claude keynote (laptop control from phone); OpenAI shipped Codex mobile + Remote SSH today; Cursor shipped MS Teams integration 5/11 + cloud Dev Environments 5/13. The 'agent goes where you go' battle is escalating fastSource: OpenAI (openai.com/index/work-with-codex-from-anywhere/), TechCrunch, Axios, Engadget, 9to5Mac, SiliconANGLE · 2026-05-14
  • API DEPRECATION -- RETIREMENT DATE IS TODAY, 2026-08-10 (announced 2026-05-08; re-verified against the live deprecations doc 2026-08-10): **gpt-5.2-chat-latest** and **gpt-5.3-chat-latest** model snapshots retire **August 10, 2026**. These are distinct from the 4/22 legacy snapshot batch (gpt-5-chat-latest + gpt-5.1-codex retired 7/23; o1-2024-12-17 + ft-gpt-3.5-turbo + ft-gpt-4 retire 10/23) -- the 5/8 entry covers the GPT-5.2 / GPT-5.3 'chat-latest' rolling-pointer snapshots specifically. **CORRECTION TO OUR EARLIER GUIDANCE:** this page previously said to migrate to 'the current chat-latest alias (which routes to GPT-5.5)'. That is no longer what OpenAI's doc says -- **the deprecations table now names `gpt-5.6-sol` as the recommended replacement for both snapshots**. If you have code or fine-tunes pinned to either snapshot ID and have not migrated, calls fail from today; move to `gpt-5.6-sol` or pin a versioned snapshot ID for stabilitySource: OpenAI deprecations doc (developers.openai.com/api/docs/deprecations.md -- '2026-05-08: gpt-5.2-chat-latest and gpt-5.3-chat-latest model snapshots' section, retirement table rows 'Aug 10, 2026 | gpt-5.2-chat-latest | gpt-5.6-sol' and 'Aug 10, 2026 | gpt-5.3-chat-latest | gpt-5.6-sol', fetched 2026-08-10) · 2026-08-10
  • CORPORATE (2026-05-11): OpenAI launched 'The Deployment Company' -- a new majority-owned OpenAI subsidiary with $4B initial investment from 19 partners (TPG, Goldman Sachs, Bain Capital, McKinsey + 15 others). Mission: embed Forward Deployed Engineers (FDEs) inside client organizations to accelerate enterprise AI deployment beyond what an API + consulting can deliver. Concurrent: acquired Tomoro (~150 AI engineers) to seed the FDE bench. Strategic frame: a delivery layer for GPT-5.x / Codex / future models inside Fortune-500 client orgs, competing with Accenture / McKinsey on AI implementation but with vendor-aligned incentives. NOT a new ChatGPT feature -- this is a services-arm spin-out. Implications for buyers: lock-in risk if you sign with the Deployment Company (deploys against OpenAI models specifically); upside is faster time-to-value on Codex / GPT-5.5 agentic workflows. openai.com/index/openai-launches-the-deployment-company/ returned 403 on direct WebFetch (anti-bot, expected); confirmed via OpenAI's official X announcement + tier-1 press (Axios, PYMNTS, CNBC).Source: OpenAI X (twitter.com/OpenAI/status/2053824997777457651), Axios, PYMNTS, CNBC · 2026-05-11
  • GPT-5.5 'Spud' launched 2026-04-23 in ChatGPT (Plus/Pro/Business/Enterprise) + Codex (Plus/Pro/Business/Enterprise/Edu/Go). Model IDs gpt-5.5 and gpt-5.5-pro. ChatGPT Free tier NOT included. OpenAI-published launch benchmarks: Terminal-Bench 2.0 82.7% (SOTA, +7.6 over GPT-5.4), SWE-Bench Pro 58.6%, GDPval 84.9% (SOTA), OSWorld-Verified 78.7%, ARC-AGI-2 85.0% (+11.7 over GPT-5.4's 73.3 on ARC-AGI-1), FrontierMath Tier 4 35.4% base / 39.6% Pro, Humanity's Last Exam 52.2% (with tools), MRCR 512K-1M 74.0% (+37.4 over GPT-5.4's 36.6 -- the biggest material delta). Cyber capability classified 'High' under OpenAI's Preparedness Framework (below Critical). No GPT-5.4 deprecation announced -- GPT-5.4 remains live. Third-party verification of launch benchmarks pendingSource: OpenAI Introducing GPT-5.5 (primary), Axios · 2026-04-23
  • GPT-5.5 API SHIPPED 2026-04-24 (~24 hours after ChatGPT consumer launch). Both gpt-5.5 ($5/$30 per 1M tokens) and gpt-5.5-pro ($30/$180 per 1M) are now live via OpenAI API. Cached-input pricing revealed: $0.50/M cached input (90% discount vs standard input), Batch + Flex tiers at 50% of standard, Priority at 2.5x. Faster API rollout than expected -- yesterday's launch post said 'coming very soon' and it shipped in under 36 hoursSource: OpenAI API docs, apidog, the-decoder (verified 2026-04-24) · 2026-04-24
  • GPT-5.5 pricing jumped 2x vs GPT-5.4 on the API: $5/$30 per 1M tokens input/output (vs $2.50/$15 for GPT-5.4). GPT-5.5 Pro is $30/$180 per 1M -- the most expensive frontier LLM API on the market today. Batch + Flex = 50% of standard rate; Priority processing = 2.5x standard. For budget-sensitive workloads, GPT-5.4 at half the token cost remains a defensible choice where GPT-5.5's agentic/coding gains don't applySource: OpenAI Introducing GPT-5.5 pricing section · 2026-04-23
  • DEFAULT MODEL CHANGE (2026-05-05): OpenAI made GPT-5.5 Instant the new ChatGPT default model, replacing GPT-5.3 Instant for all users. Per OpenAI release notes: factual reliability up, tighter answers, fewer follow-ups, reduced overformatting/emoji clutter, better use of past-chats / files / Gmail context. Paid users keep GPT-5.3 Instant access via model picker for ~3 months (~Aug 2026 retirement). GPT-5.3 Instant Mini became the new fallback for free-tier rate-limited users, replacing GPT-5 Instant Mini. GPT-5.5 Instant is distinct from GPT-5.5 Thinking (already in Plus / Pro / Business / Enterprise since 2026-04-23) -- Instant is the lighter-latency default; Thinking is the higher-effort variantSource: OpenAI ChatGPT release notes (help.openai.com/en/articles/6825453-chatgpt-release-notes) · 2026-05-05
  • REALTIME API REPLACEMENT SHIPPED (2026-05-07, TODAY): The Realtime API Beta header (`OpenAI-Beta: realtime=v1`) and all gpt-4o-realtime/audio-preview snapshots retired today as scheduled. **Actual replacements differ from prediction**: OpenAI shipped THREE new GA models (not the gpt-realtime-1.5 / mini / audio-1.5 / mini naming initially in the deprecation page). Real names: **GPT Realtime 2** (first voice model with GPT-5-class reasoning, $32/M audio input + $64/M audio output -- same as prior gpt-realtime), **GPT Realtime Translate** (70+ input languages -> 13 output, billed by minute at $0.034/min), **GPT Realtime Whisper** (live streaming STT, $0.017/min).

  • FINE-TUNING PLATFORM STAGED SUNSET (2026-05-07 effective TODAY -- multi-stage): The OpenAI Fine-Tuning Platform begins a phased shutdown announced on the deprecation page. **Stage 1 (TODAY 2026-05-07)**: fine-tuning job creation closed for NEW organizations -- if you haven't already created an FT job by today, you can no longer start. **Stage 2 (2026-07-02)**: existing FT jobs blocked if no inference activity in past 60 days. **Stage 3 (2027-01-06)**: no new FT jobs even for existing customers. This is a platform-level wind-down, not just a model deprecation -- distinct from the 4/22 ft-gpt-3.5-turbo + ft-gpt-4 snapshot retirement (10/23)Source: OpenAI deprecation page (developers.openai.com/api/docs/deprecations) · 2026-05-07
  • CHATGPT ADS SELF-SERVE BETA (2026-05-05 - 2026-05-07 rollout): OpenAI launched a self-serve advertiser platform at ads.openai.com targeting ChatGPT Free and Go users (logged-in adult US users only). Cost-per-click bidding ($3-5/click recommended starting bid), Conversions API + pixel-based measurement, US advertisers only at beta launch. Ad-free remains on Plus / Pro / Business / Enterprise tiers per the 2026-02-04 commitment. Material because it confirms OpenAI's monetization-of-Free strategy is going end-to-end self-serve (was previously Sales-mediated) -- expect inventory + targeting expansion in coming monthsSource: OpenAI: Testing ads in ChatGPT (openai.com/index/testing-ads-in-chatgpt/), Axios 2026-05-05 · 2026-05-05
  • API DEPRECATION (2026-04-22): OpenAI added a 'Legacy GPT model snapshots' batch to the deprecation page. Headline retirements: gpt-5-chat-latest and gpt-5.1-codex shut down 2026-07-23. o1-2024-12-17 and ft-gpt-3.5-turbo (and ft-gpt-4) shut down 2026-10-23. Replacements per OpenAI: gpt-5-chat-latest -> gpt-5.3-chat-latest; gpt-5.1-codex -> gpt-5; o1-2024-12-17 -> o3; ft-gpt-3.5-turbo -> gpt-4.1-mini. The o1 retirement closes out the original reasoning-model family. If your code or fine-tunes target any of these snapshots, migration work needs to land before the respective shutdown date or the API call will start failingSource: OpenAI deprecations page (developers.openai.com/api/docs/deprecations -- 2026-04-22 entry) · 2026-04-22
  • ChatGPT Images 2.0 / gpt-image-2 launched 2026-04-21 -- OpenAI's first image model with native reasoning ('thinks before it draws'), 3:1 to 1:3 aspect ratios, generates up to 8 related images with character/object continuity across the set, materially better multilingual text rendering. Free tier gets standard outputs; advanced thinking-mode gen is gated to Plus / Pro / Business / Enterprise. Reportedly took #1 on Image Arena leaderboard within 12 hours by ~242 Elo points (largest first-day jump on record). API model id: gpt-image-2. Bundled deprecation: DALL-E 2 + 3 retire 2026-05-12 -- code calling legacy endpoints will failSource: OpenAI Introducing ChatGPT Images 2.0, Tom's Guide, The New Stack · 2026-04
  • GPT-4o, GPT-4.1, GPT-4.1-mini, and o4-mini were retired on 2026-02-13 (ChatGPT) / 2026-02-16 (API). Business/Enterprise/Edu Custom GPTs had grace period through 2026-04-03. If you have older prompts or agents hardcoded to 'gpt-4o', they are broken -- migrate to GPT-5.2 or GPT-5.4Source: OpenAI deprecations, TechCrunch backlash coverage · 2026-02
  • New $100/mo Pro tier launched 2026-04-09 (between Plus $20 and Pro Ultra $200). OpenAI positioned it explicitly as a response to Claude Max pricing. Existing $200 Pro is retained for unlimited usage; the $100 tier offers 5x Plus quotas and 10x Codex during the launch promo through 2026-05-31Source: OpenAI community post, TechCrunch, The Next Web · 2026-04
  • Legacy Deep Research mode was removed from ChatGPT on 2026-03-26 -- replaced by the newer agentic Deep Research. Users who preferred the old behavior (more predictable, less agentic) have no direct replacementSource: OpenAI help changelog · 2026-03
  • ChatGPT Business annual was cut from $25 to $20 per seat on 2026-04-02 -- a rare downward pricing move. Existing customers on the $25 tier should check whether their renewal reflects the new rateSource: OpenAI pricing page · 2026-04
  • Memory feature sometimes surfaces irrelevant stored memories or forgets things it should rememberSource: Reddit r/ChatGPT · 2026-03
  • Custom GPTs occasionally break when OpenAI updates modelsSource: OpenAI Community Forum · 2026-02
  • GPT-5.4 Thinking mode latency can be 30+ seconds for complex queries -- frustrating for back-and-forth useSource: Reddit r/ChatGPT · 2026-04

Best for

Everyone. Seriously -- if you're new to AI or want the most complete all-in-one package, ChatGPT is the default recommendation.

Not for

Power users who need the absolute best writing quality (Claude) or total privacy (local Llama). Also not for anyone opposed to OpenAI's data practices.

Our Verdict

ChatGPT is the Toyota Camry of AI chatbots. It's not the flashiest or the absolute best at any one thing, but it does everything well, it's reliable, and the ecosystem around it is massive. The July 9, 2026 wave is the biggest single week in the product's history: GPT-5.6 GA (Sol/Terra/Luna, with `ultra` multi-agent mode), GPT-Live full-duplex voice, the ChatGPT Work agent, and a unified desktop app free on every plan. OpenAI's pitch shifted from raw capability to performance-per-dollar -- and on July 30 it made that literal, cutting Luna 80% to $0.20/$1.20 and Terra 20% to $2/$12 while leaving Sol alone. On August 6 it pushed that logic down to the free tier: Luna by default, unlimited text chats, and a Think button, which makes the free plan genuinely hard to beat. Paid users got ergonomics rather than capability -- one model and an effort slider instead of the Instant/Thinking split -- and that retune stops at the Chat surface, so Codex and Work behave exactly as they did. For most people, this is still the only AI chatbot they need, and the gap to needing anything else just narrowed again.
