From the research report

Landscape Report, October 2026 edition — §1.1.

What happened recently: GPT-6 Astra launched Sep 3, 2026 — 1.05M-token context, positioned for computer use, software engineering, science, and professional work (TechCEO Daily, 9/30/26). It's the first OpenAI frontier model shipped in a restricted public version (cybersecurity capabilities held back). Its successor checkpoint GPT-6.1 Astra was cancelled Sep 28, 2026 for failing internal scope/safety tests (Reuters/Newsweek via explainx.ai, 10/4/26 — very fresh, worth re-verifying before citing to clients). At DevDay (Sep 29, 2026), OpenAI launched Dots: always-on agents powered by GPT-6 Astra, each with its own cloud computer + browser, 4,000+ app plugins, reachable from ChatGPT, Slack, and Teams (SMS "coming soon"). Custom rules govern act-alone vs. ask-permission; background tools are read-only; password changes stay human-side (BetaNews, 9/30/26). Custom GPTs are being retired (announced Sep 11, 2026, migrating to plugins, no end date yet — felloai, updated 10/5/26).

Pricing (current):

• Consumer: Free $0 (ad-supported in US/EU); Go $8/mo; Plus $20/mo; Pro $100 / $200 / $500-mo tiers — Pro 500 ($500/mo) added at DevDay with ~25x Plus usage (secondary, felloai 10/5/26).
• Business (primary source: openai.com/api/pricing, fetched 10/6/26): Business Standard $20/user/mo annual ($25 monthly); Business Premium $100/user/mo annual ($125 monthly, 5x usage, workspace agents); Enterprise custom (credit- or token-based). 2–200 seats on Business.
• API (secondary, felloai 10/5–6/26): GPT-6 Astra $10 input / $50 output per 1M tokens; GPT-6.1 Sol $2/$10; GPT-6 Luna $0.10/$0.50; GPT-5.6 Sol $4/$20 (promo through Nov 21, 2026).
• Update 2026-10-14 (primary: OpenAI Help Center, About ChatGPT Pro tiers): Pro is now three tiers — Pro 100 ($100), Pro 200 ($200), Pro 500 ($500, includes Ultrafast). Pro 200 reopened to new subscriptions at a lower included allowance than before; subscribers active Sep 22–29, 2026 keep the previous allowance only through Oct 29, 2026, then move to the lower allowance at the same $200 price.

Agent-building features: Dots (one included with Pro and Business Premium at no extra cost; one Dot per user at launch — matches Chris's verified constraint); Agents API, computer use, Decisions API, MCP events, plugin extensions, hosted shell, Skills; 4,000+ app plugin ecosystem.

Key limits: One Dot per user at launch (teams of Dots "coming over time"); Dots Pro rollout excludes EEA/Switzerland/UK; Plus users get Astra only in ChatGPT Work and Codex, not chat; no training on business data by default; Astra's public version is capability-restricted.
