OpenAI has deployed its GPT‑6 Astra model to Plus, Pro, Enterprise, Business Standard and Premium tiers across ChatGPT Work, Codex and the API, with Business and Pro plans now on $100/$200 monthly options.
OpenAI has begun shipping its newest language model, GPT‑6 Astra, to a broad swathe of its paid tiers. The rollout, announced on 3 September 2026, first reached a limited set of partner organisations and, as of today, is live for ChatGPT Pro, Enterprise and Business Premium users within the ChatGPT Work and Codex environments. The model is also available through the OpenAI API under the identifier **gpt‑6‑astra**, and will be reachable via Microsoft Azure and Amazon Bedrock in the coming days. A subsequent update confirmed that users on the $100‑per‑month and $200‑per‑month Business and Pro plans will gain access within 24 hours.
GPT‑6 Astra brings a 1 million‑token context window, faster compute and searchable context, positioning it as a step up from the previous GPT‑4 generation. Pricing for API usage is set at $10–$50 per million tokens, while the model is off by default for enterprise workspaces, requiring administrators to enable it per deployment. The expanded token limit promises more coherent long‑form outputs and richer code‑generation capabilities in Codex, a feature that could accelerate development cycles for businesses that rely on AI‑assisted programming.
The release matters because it marks OpenAI’s first model with a context window an order of magnitude larger than its predecessor, potentially reshaping how enterprises embed generative AI in products, internal tools and customer‑facing services. It also intensifies competition with rivals such as Anthropic, which recently demonstrated autonomous theorem‑proving work using its Claude model.
Going forward, observers will watch adoption rates across the Plus, Business Standard and Enterprise tiers, performance benchmarks against GPT‑4, and any pricing adjustments as usage scales. Integration progress with Azure and Bedrock, as well as how quickly enterprise admins enable the model, will indicate how quickly GPT‑6 Astra becomes a staple of the AI stack.
