Known issues we've tracked

GPT-6.1 SOL ULTRAFAST REACHES THE API RATE CARD; COMPOSER PREDICTIONS BETA IN THE CODEX DESKTOP APP (rate card checked 2026-10-12; predictions 2026-10-09, vendor-primary): **(1) Ultrafast.** The API pricing page's Ultrafast table now lists **gpt-6.1-sol at $12.00 input / $0.60 cached input / $15.00 cache writes / $60.00 output per 1M tokens for short context (up to 272K input), and $24.00 / $1.20 / $30.00 / $90.00 above 272K**, beside gpt-6-astra at $60 / $6 / $75 / $300. That is exactly six times GPT-6.1 Sol's Standard rates, matching the Enterprise rate card's 6x Ultrafast multiplier. It closes the DevDay promise of GPT-6.1 Sol Ultrafast 'in the coming days'; the 10/05 sweep recorded the table as Astra-only, so the row landed between 10/06 and 10/12 -- the exact date is not published. **(2) Composer predictions (beta).** 'Suggests your next message based on the conversation in your current Codex thread'; Tab accepts, nothing sends automatically, and the composer may skip a prediction. **Eligibility: adults on personal ChatGPT Pro plans, in the Codex desktop app, in local and SSH threads, with GPT-6 Astra or GPT-6.1 Sol**; on by default (Settings > General > Composer > Show predictions); not in Chat, not on other plans, and in Work only for local threads. **During the beta, generating predictions does not count toward Codex usage limits or consume credits**; sent messages bill normally. Predictions use only the current thread's context and do not query memory or connected apps on their own.

ATLASSIAN PARTNERSHIP EXPANDED -- GPT-6 MODELS POWER ROVO, 3,000+ ATLASSIAN DEVELOPERS ON CODEX, JIRA AND CONFLUENCE CONTEXT VIA CLI PLUGINS (2026-10-06, vendor-primary): OpenAI and Atlassian 'are expanding their partnership, bringing frontier models in the GPT-6 family across Atlassian's platform'. **Under a new agreement, OpenAI frontier models will power agents across Atlassian's platform and Rovo**, which pairs OpenAI models with Atlassian's Teamwork Graph ('an enterprise context layer that connects people, projects, documents, and decisions'); Atlassian gets 'expanded access to the latest OpenAI frontier models, including GPT-6 Astra and the GPT-5.6 series'. **Codex-specific facts:** 'More than 3,000 Atlassian developers use Codex across their terminals, IDEs, and code review workflows'; 'through the Atlassian and Teamwork Graph CLI plugins for ChatGPT and Codex, customers can connect ChatGPT and Codex to their existing workflows, giving AI access to relevant project information, documentation, and development context, subject to appropriate permissions'; and Atlassian's recent plugin extension 'brings Jira work items, Confluence content, and people directly into ChatGPT and Codex prompts', with a pinned Atlassian Home surfacing assigned work, recent Looms, projects and Bitbucket pull requests. **Roadmap, not shipped:** the companies 'are exploring deeper integrations with Jira that would make it easier for teams to assign work to AI agents, track progress, capture decisions, and review results', paired with DX (Atlassian's developer-productivity measurement platform) to measure AI's effect on development speed and cycle time. OpenAI says it will 'continue to rely on Jira' internally; the collaboration dates to 2023. No pricing or plan change -- this is distribution and context for Codex users on Atlassian stacks, and a direct answer to the Jira workflows GitHub Copilot and Cursor already pitch.

EU TEXT WATERMARK ON CODEX OUTPUT, OPT-IN WATERMARKING ON THE API, AND AN ENTERPRISE RATE CARD THAT NAMES THE CODE-REVIEW MODELS (2026-10-04/05, vendor-primary): **(1)** 'Our approach to EU text provenance rules' (10/05): 'Over the coming weeks, we will introduce text watermarking to eligible ChatGPT and Codex users across all plans in the EU only' -- so the watermark lands on Codex text output in the EU by default, and 'starting today, API customers around the world will be able to opt in to watermarked text outputs for select models' (off by default in the API; cloud partners to follow). The scheme, textGrain, is a statistical signal in word choice; OpenAI's own figures put detection at about 80% for 200-token and 95% for 400-token passages at a 1% false-positive rate, falling to 66% and 17% after 10% and 25% synonym edits, and 'substantially lower' for mathematics-style text. Astra at max effort scored within noise with the mark on (DeepSWE v1.1 72.80% vs 71.68%, Terminal-Bench 4.0 53.90% vs 56.06%). Detector access is limited to approved researchers. For code this is mostly a non-event in practice (identifiers and syntax leave little word-choice freedom, which is exactly the case OpenAI says detection is weakest), but EU teams with provenance or compliance questions should expect the default. **(2)** The Enterprise token rate card (help center, updated ~10/04) prices Codex for eligible token-based Enterprise agreements at the API Standard rates -- GPT-6 Astra $10 / $1 / $50, GPT-6.1 Sol $2 / $0.10 / $10, GPT-6 Sol $2 / $0.20 / $10, GPT-6 Luna $0.10 / $0.01 / $0.50, GPT-5.3-Codex $1.75 / $0.175 / $14 per 1M input / cached / output -- and states that **code review uses GPT-5.3-Codex and auto review uses GPT-5.6 Luna**, that charges cover 'local tasks, cloud tasks, automations, code review, auto review, and delegated workers', that **Codex does not charge for cache writes and GPT-6 Astra in Codex has no long-context multiplier above 272K**, that Fast mode is 2x and **GPT-6 Astra Ultrafast is 6x Standard** (8x against an included allowance), and that Codex Security Cloud's Daybreak Blue runs at GPT-5.6 Sol rates ($4 / $0.40 / $20) with Daybreak Red at $12.50 / $1.25 / $75. **(3) Still pending:** as of 10/05 the API pricing page's Ultrafast table lists only gpt-6-astra ($60 / $6 / $75 / $300); the GPT-6.1 Sol Ultrafast tier promised at DevDay 'in the coming days' has not appeared on the rate card.

DEVDAY 2026 FOR CODEX: GPT-6.1 SOL, CODEX CLOUD, A VOICE-STEERED CLI, CODE REVIEW, SECURITY CLOUD, COMPUTER USE IN THE AGENTS API, AND AN ULTRAFAST TIER THAT ONLY PRO 500 AND ENTERPRISE GET (2026-09-29, vendor-primary): **(1) GPT-6.1 Sol** -- 'an upgrade to GPT-6 Sol that nearly matches GPT-6 Astra's intelligence on agentic coding, computer use, and professional work at one-fifth of Astra's standard input and output token prices'; on DeepSWE v1.1 it 'matches GPT-6 Astra at roughly one-fifth of the cost, while eclipsing GPT-6 Sol's best score by 6.4 percentage points at a lower reasoning effort and cost'. API id `gpt-6.1-sol`, **$2 / $0.10 cached / $2.50 cache writes / $10 per 1M** (pricing.md), 1,050,000 context, 128,000 max output, Apr 30 2026 cutoff; effort low to max with none and minimal unsupported; Responses API for tool calling. 'Available starting today to all Plus, Pro, Business, Enterprise, and Edu users in ChatGPT Work and Codex' (release note: starting with Pro, expanding to Plus, Business, Enterprise and Edu). **GPT-6.1 Sol Ultrafast** -- 'up to 8x faster token generation compared to its standard speed in Codex' -- is 'in the coming days'. **(2) Ultrafast as a tier** -- 'our premium speed tier for workloads where speed matters most', 'up to 8x faster token generation (300 tokens per second) in Codex and up to 6x in the API'; **GPT-6 Astra Ultrafast is live in the API at $60 / $6 / $75 / $300 per 1M and in ChatGPT Work and Codex on Pro 500 ($500/month) and Enterprise only** -- 'Buying credits on Pro 100 or Pro 200 does not unlock it.' **(3) Codex Cloud** -- 'start and continue coding tasks from desktop, web, or mobile using reusable environments with your project's repositories, tools, and dependencies. Each task gets its own isolated workspace, and tasks can continue while your computer is asleep'; managed workspaces apply their cloud-access settings; Plus, Pro, Business, Healthcare, Education and Enterprise. **(4) Refreshed Codex CLI** -- start and steer tasks by voice, a new /agents view to delegate and track multiple tasks, prompt editing, session resume, worktrees and a cleaner terminal UI; all plans. **(5) Code Review** -- read PR summaries and diffs, review findings and ask Codex about issues before commenting on GitHub pull requests or GitLab merge requests; 'with automatic reviews, Codex can also take a first pass in the cloud while you're away'; all plans via the Code Review plugin. **(6) Codex Security Cloud** -- scan GitHub repositories on demand or on a schedule with ongoing checks of new commits; Codex investigates findings, removes duplicates and prepares fixes in the cloud; **'includes access to models offered through Daybreak Blue without a separate Daybreak application'** (the release note phrases it as Daybreak Blue models 'only within Codex Security Cloud'); Pro, Business, Enterprise and Edu; existing Codex Security customers opt in before paid usage. **(7) Agents API with computer use** -- the Agents API 'now supports computer use so developers can build agents that interact with software', and brings Codex's multi-agent, tool search, tool calling and context compaction into your app; available through the API and in Codex and ChatGPT Work on Pro 500 and Enterprise. **Bedrock Managed Agents, powered by OpenAI**, runs the same core in AWS. **(8) Decisions API** -- Luna focused on user-defined questions with finite answers for classification, routing and next-action choice; limited preview, broad release 'in the coming days'. **(9) VS Code cross-over (GitHub changelog, 10/01):** 'Pick up a Codex conversation from the ChatGPT app in VS Code' and open the PR form from a Copilot, Claude or Codex agent session in the Agents window. **(10) Deprecation (10/01):** `gpt-5.3-codex` is deprecated and 'will be removed from the API on April 1, 2027' with gpt-6-sol as the replacement.

GPT-6 SOL AND LUNA IN CODEX FROM LAUNCH DAY -- HALF-PRICE API TIERS, 1.05M CONTEXT, AND A CACHE THAT SURVIVES EFFORT CHANGES (2026-09-22, vendor-primary): OpenAI's launch post says GPT-6 Sol and Luna 'are available in ChatGPT Work and **Codex** starting today for all Plus, Pro, Business, Enterprise, and Edu users. Free and Go users can access GPT-6 Luna in the desktop app'; the ChatGPT release note for the same day adds that 'Codex desktop keeps the model you selected manually' and that 'available models and reasoning effort options depend on your plan and workspace settings'. **API pricing (developers.openai.com pricing.md):** `gpt-6-sol` **$2 / $10** per 1M (cached $0.20, cache writes $2.50; above 272K input the whole request bills 2x input and 1.5x output), `gpt-6-luna` **$0.10 / $0.50** (cached $0.01) -- 'reducing API prices for Sol and Luna by 50% compared with their GPT-5.6 promotional pricing'; Batch/Flex half, Fast mode double. Model pages: 1,050,000 context, 922,000 max input, 128,000 max output, reasoning tokens, image input, structured outputs; Sol cutoff Apr 20 2026, Luna May 18 2026. **Coding claims (OpenAI's numbers, competitor scores from public reports):** DeepSWE v1.1 -- **Sol (max) 68.8%**, 'within 1.1 percentage points of Claude Fable 5's highest score' (69.9%) at ~80% lower cost per task; **Luna (max) 66.6%**, 'comparable to Claude Opus 5 and Fable 5 at medium effort' at 93-96% less per task; FrontierCode 1.1 -- Sol 'improves substantially over GPT-5.6 Sol' and matches Fable 5.1 xhigh at much lower cost (Anthropic's 9/28 table gives Sol 52.1% at xhigh vs Sonnet 5.5's 49.3% and Opus 5.5's 54.4%). OpenAI also disclosed internal usage: daily token spend at API prices 'has exceeded $600 for the median researcher and $7,000 for researchers at the 90th percentile'. **Prompt caching rebuilt for GPT-6:** discounts for eligible shared prefixes reused within a 30-minute window, 90% off cached input, a Prompt Caching Dashboard, a diagnostics tool that names the miss reason and affected tokens, explicit cache breakpoints, reasoning-effort changes via `configuration_update` that preserve the cache, `allowed_tools` / `tool_choice: none` instead of deleting tool definitions, and prewarming -- GitHub reports more than 50% fewer prompt tokens needing fresh processing across billions of Copilot requests. Cross-vendor context: the same week Anthropic shipped Opus 5.5 (9/22, $4/$20) and Sonnet 5.5 (9/28, $2/$10), so the $2/$10 Sol vs Sonnet 5.5 comparison is now the live one for agentic coding spend.

THE AGENTS API -- CODEX'S HARNESS BECOMES A HOSTED PRODUCT, IN PUBLIC BETA, WITH NO SURCHARGE (2026-09-10, vendor-primary): OpenAI introduced the **Agents API** in public beta, 'bringing that same harness and infrastructure that powers Codex to developers through a simple, flexible API.' **What you get in one call** (`client.beta.agents.sessions.create`): a model (the example is `gpt-6-astra`), tools (MCP servers, custom functions, built-ins like web search), a `multi_agent` block with `max_concurrent_subagents`, secrets via `vault_ids`, and an `environment` -- either **`openai_hosted`** (a new OpenAI-managed sandbox on 'the same sandboxing infrastructure that powers Codex and ChatGPT', configurable with files, packages, skills and plugins) or your own infrastructure or a partner sandbox. **Named sandbox partners:** Blaxel, Cloudflare, Daytona, DigitalOcean, E2B, Modal, Oracle, Runloop, Vercel. **Harness features OpenAI calls out as maintained for you:** automatic **context compaction** as a session nears its window, **tool search** (loads tool definitions on demand to save tokens and preserve cache), **programmatic tool calling** (parallel calls, chaining and in-code filtering so only relevant results re-enter context), and **subagents** with their own context. OpenAI says the harness is 'versioned' and improved with each model launch, so you inherit upgrades without rewriting scaffolding; it is 'powered by the open-source Codex harness', so the coordinating logic is inspectable. **PRICING: 'There are no additional fees for using the Agents API -- you simply pay for the tokens and tools your agents use.'** That is the notable commercial decision: OpenAI is not charging for orchestration or the hosted sandbox line item at beta, which undercuts the agent-infrastructure vendors it is simultaneously partnering with. **CUSTOMER CLAIMS (vendor-selected, unverified):** Ciridae eval score 0.71 -> 0.85 and 4x latency reduction on subagent flows; SafetyKit 60% lower cost per case; Hypha 86% fewer failed agent responses; Nash running 'thousands of long-running AI agents' on it. **HOW TO READ IT ON THIS PAGE:** Codex the product (CLI, IDE, cloud, app) is unchanged; what changed is that its runtime is now a platform primitive, which is the clearest statement yet of where OpenAI thinks the moat is -- the harness and infrastructure rather than the model alone. Beta means the API surface can change before GA; OpenAI says it will 'iterate quickly' on feedback.

**Oct 15: @GitHub in Slack and Microsoft Teams now works across multiple repositories in a single conversation (issues, pull requests, bug investigations), can be mentioned anywhere in a message, and can use shared Slack messages and threads as context.** **Gemini 4 Argon joined Copilot on 2026-10-13, the day Google made it GA, for Pro+, Max, Business and Enterprise at provider list price; on 10/15 GitHub scheduled Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra for removal from every Copilot surface on 2026-11-16 (Opus 4.8 stays for individual annual subscribers), and HydraFusion gained a Max option and a pool of Opus 5.5, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna (10/14).** **Claude Haiku 5.5 joined Copilot on 2026-10-07, the day Anthropic launched it, for Pro, Pro+, Max, Business and Enterprise at provider list price; the same day local sandboxing went GA in Copilot CLI, the Copilot app and VS Code Agent Host at no extra cost, the CLI learned to discover local Ollama models, and GitHub announced a purpose-built secret-detection model whose new push-protection and /security-review checks will draw AI Credits.** **GPT-6.1 Sol landed in Copilot on OpenAI's launch day (2026-09-29, Pro+/Max/Business/Enterprise), the fifth day-one frontier add in eight days, and on 2026-10-02 the four-model retirement slate executed on schedule: Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code and Claude Opus 4.7 are gone from every Copilot surface.** Same week: HydraFusion's multi-model orchestration reached VS Code 1.140 and the Copilot app (9/30), **computer use** let Copilot CLI and the Copilot app drive desktop applications on macOS and Windows in public preview (10/01), dynamic workflows defined in code arrived for CLI, app and SDK (10/01), the September VS Code roundup added automations, agent merge and Dev Container sessions (10/01), and Copilot code review gained REST/GraphQL request support with Balanced as the default effort level (10/02). Still ahead: the six-model slate on 10/19 and the 10/22 default policy for new features for Business and Enterprise. The 9/22 and 9/28 adds (Opus 5.5, GPT-6 Sol/Luna, Sonnet 5.5) all stand, metered at provider list pricing.

**Oct 16: cloud agents can now build interactive canvases and share them by link, the Environments API entered beta for creating and managing agent environments in code, and cloud agent environments hold up to 300 repositories with large environments loading 5x faster.** **Cursor's own plans closed to new customers on 2026-10-12: Cursor is now sold through The X Subscription (Free, Plus $8, Premium $30, Super $100, Ultra $200) with one usage pool shared with Grok, at least twice the coding usage on SpaceXAI's models -- but Claude, GPT and Gemini are no longer in the allowance, billed at API list price on Premium and up and unavailable on Plus. On 2026-10-06 the Cursor iOS app gained remote control of local agents.** **Cursor launched two bots for the last mile of shipping code on 2026-09-23 (Teams and Enterprise): Rollouts, which attaches a monitor to every pull request and watches the change as it deploys per environment -- verified healthy, regression detected, or inconclusive -- and Security Review, which posts one comment per PR reporting exploitable bugs with severity, attack path and a proposed fix.** Rollouts is the Cursor rebuild of Firetiger's Change Monitors on the Bot Development Kit; it can open a revert PR or hand a regression to a cloud agent but does not merge or roll back on its own. Models: Anthropic's 9/28 Sonnet 5.5 post quotes SpaceXAI's Sualeh Asif on CursorBench 4.0 -- Sonnet 5.5 at 55.5% 'second only to Opus 5.5' (57.8%); Grok 4.7 and its Cursor-only Fast variant arrived 9/21. **Cursor Projects (9/10, beta)** and the 11/12 OpenAI shutoff watch continue.

Claude Code

7.8

**2.1.302 (2026-10-16) added CLAUDE_CODE_AUTO_MODE_MODEL to choose the model behind the client-side auto-mode classifier, an Idle compaction on/off row in /config, and a notice in /design-sync and /design-login that standalone Claude Design (claude.ai/design) closes by 2026-12-14; it also fixed file writes on exFAT/FAT32 drives on Windows and stopped prompt suggestions spending credits.** **2.1.299 (2026-10-14) added idle compaction -- a 200K+ token conversation left idle about 54 minutes is compacted before its one-hour prompt cache expires -- plus /effort and /fast defaults in agent view and /usage warnings for max effort and large tool results; 2.1.300 (10/14) brought /advisor to Claude Platform on AWS; 2.1.301 (10/15) lets unattended retry mode give up on far-off usage-limit resets and makes the fable alias fall back to the previous Fable model.** **Claude Haiku 5.5 became the default Haiku in 2.1.293 (2026-10-07) at $0.10 / $0.50 per 1M below 100K tokens; 2.1.295 (10/08) added onFailure block for hooks, OSC 7501 terminal status, per-upstream model lists on the Claude apps gateway and a 16,384-character limit on tool-search MCP descriptions, and 2.1.296 (10/09) added an allow_large Read option, per-subagent autoCompactWindow and a code policy key for Claude Desktop's Code tab.** **Three releases in two days -- 2.1.290 (2026-10-05), 2.1.291 and 2.1.292 (both 10/06): claude attach and claude logs by session name, a /claude-api managed-agents-onboard command, an effort parameter on the Agent tool, --marketplace on claude plugin install, a configurable 529 retry delay, WebFetch continuation past 100,000 characters, local MCP servers defaulting to protocol 2026-07-28, and a long run of security fixes for symlink and UNC-path reads; no model or pricing changes.** Anthropic's terminal-based coding agent that reads your whole repo and makes real changes -- not just suggestions. **Claude Opus 5.5 became the default Opus model in 2.1.280 (2026-09-22) and Claude Sonnet 5.5 the default Sonnet in 2.1.284 (2026-09-28)**: Opus 5.5 at $4/$20 with $0.20 cache reads and fast mode at $8/$40 for up to 2.5x speed, Sonnet 5.5 at an unchanged $2/$10 with far fewer tokens per task. Both are 1M context. Fable 5.1 (2026-09-01) remains the top model and still defaults to High effort in Claude Code specifically. **Four more releases 9/29-10/02 (2.1.285-2.1.288) added Claude Mods (plugins that modify deeper behaviour) with a built-in 'You should know' side agent, `claude --desktop` to hand a session to the desktop app, an `allowedProviders` managed setting, a WebFetch kill switch, `--max-findings` on /code-review, and continuation from partial responses when the API times out mid-turn.** Also since 9/22: `/doctor prompt-audit`, `deniedModels`, dollar amounts on spend limits and `attribution: false`.

About Codex (OpenAI)

Tier A (8.3/10). **GPT-6.1 Sol Ultrafast is now on the API rate card -- $12 input / $0.60 cached / $15 cache writes / $60 output per 1M up to 272K tokens, six times Standard, closing the DevDay 'coming days' promise -- and on 2026-10-09 the Codex desktop app gained Composer predictions (beta), which suggests your next message after each response for personal Pro users on GPT-6 Astra and GPT-6.1 Sol.** **OpenAI and Atlassian expanded their partnership on 2026-10-06: GPT-6 family models (GPT-6 Astra and the GPT-5.6 series are named) will power agents across Atlassian's platform and Rovo, more than 3,000 Atlassian developers already use Codex, and the Atlassian and Teamwork Graph CLI plugins connect Codex and ChatGPT to Jira, Confluence, Looms and Bitbucket pull requests.** **Two October notes: EU Codex output will carry OpenAI's invisible textGrain text watermark within weeks (API customers can opt in worldwide from 10/05), and the new Enterprise token rate card prices Codex at API Standard rates, names GPT-5.3-Codex as the code-review model and GPT-5.6 Luna as the auto-review model, and puts Astra Ultrafast at 6x.** GPT-6.1 Sol Ultrafast is still not on the API rate card as of 10/05. **DevDay 2026 (2026-09-29) was mostly a Codex release: GPT-6.1 Sol in Codex and the API at $2/$10 per 1M with cached input cut to $0.10, Codex Cloud (reusable cloud environments, tasks that keep running while your laptop sleeps, on Plus and up), a refreshed CLI with voice steering and an /agents view, Code Review in the desktop app with automatic cloud first passes, Codex Security Cloud with Daybreak Blue models and no separate Daybreak application, and the Agents API gaining computer use** -- plus GPT-6 Astra Ultrafast (300 tokens per second in Codex) on Pro 500 and Enterprise, with GPT-6.1 Sol Ultrafast 'coming soon'. GPT-6.1 Sol nearly matches GPT-6 Astra on DeepSWE at one-fifth of the token price and also landed in GitHub Copilot the same day. Still in place: GPT-6 Sol and Luna (9/22), the Agents API public beta (9/10) and the 8/31 retirement of GPT-5.4 from Codex. On 10/01 OpenAI scheduled GPT-5.3-Codex for API removal on 2027-04-01.
