Is Alexa+ Down?

The chatbot that started the AI revolution. **GPT-6 Astra launched 2026-09-03** -- OpenAI's new flagship at $10/$50 per 1M (long-context $20/$75, Fast mode 2x, no Fast mode under EU data residency), rolling out to Plus, Pro, Business and Enterprise within existing allowances, and the **first model OpenAI has ever designated Critical for cyber capability**. Enterprise access is off by default at launch. 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)

AI-powered search engine that gives cited answers instead of a list of links. **Hybrid Compute on Mac shipped 2026-09-01**: Perplexity Computer now splits a single task between cloud frontier models and a compact local model running on the Mac, with an on-device privacy gate that can mask, withhold, refuse or ask for consent before anything leaves the machine

Google's free research assistant that turns your documents into an AI you can query -- and a podcast you can listen to. **Renamed from NotebookLM to Gemini Notebook on 2026-07-16**, still a standalone product, now with in-notebook code execution and syncing across the Gemini app and Search. **Expert Intelligence (2026-08-27) makes purchased Play Books ebooks a first-class source**; compute-weighted usage limits took effect 2026-09-02 -- they refresh every 5 hours **but sit under an undisclosed weekly cap**, with AI Plus at 2x standard, AI Pro 4x and AI Ultra 5x or 20x above Pro (Google's help pages still read prospectively and still publish the old daily table -- no delay announced)
