Answer from Sep 2See the current answer
Based on official documentation and verified public announcements from OpenAI, here is the current confirmed evidence regarding
OpenAI's next flagship model and its current product lineup.
The name "GPT-6" is entirely unconfirmed and speculative. OpenAI has not published a model card, product page, or official documentation acknowledging a model named GPT-6. Instead, OpenAI's official documentation and recent product rollouts center on the GPT-5.6 family (such as the Sol, Terra, and Luna tiers).[1] [2] While community leakers, tech forums, and prediction markets commonly refer to OpenAI's next major unreleased iteration as GPT-6, OpenAI has not confirmed whether any future commercial product will use that naming convention.
There is no official release date, launch window, or roadmap timeline published by OpenAI for a next flagship successor beyond the current GPT-5.6 generation. Because an official successor model has not been announced or released, it has achieved none of the three core commercial milestones:
Because OpenAI has not published a model card, preview, or technical documentation for a next-generation flagship successor, details regarding model variants, parameter counts, context window sizes, official benchmark scores, and pricing are unpublished and unconfirmed. Any specific figures, metrics, or cost structures circulating online stem entirely from unverified leaks, third-party speculation, or community extrapolation rather than official OpenAI documentation.

The new answer gives specific rollout timing—an early-September announcement and ChatGPT expansion on October 7–8, 2026—and clarifies which models are surfaced to different ChatGPT tiers. The standing answer described staged availability but gave no dates or tier-specific model access.
The answer changed
The consensus shifted completely from providing specific details about a released model named 'GPT-6 Astra' (including specs, benchmarks, and pricing) to stating that no such model name, release, or pricing can be confirmed from official sources.

The consensus changes from GPT-6 being entirely unconfirmed and unreleased to GPT-6 Astra being officially announced, partially deployed, and documented with specific capabilities, benchmarks, context limits, safety classification, and pricing.
Read this versionThe answer changed
The new answer omits and effectively contradicts the old answer’s central claim that OpenAI officially confirmed an internal unreleased model called Astra. It instead states that no successor has been officially announced, changing the conclusion about what OpenAI has publicly acknowledged.
