Answer from Aug 3See the current answer
OpenAI has not announced a release date for GPT-6. As of August 2026, there is no confirmed public launch window, API model entry, system card, or official announcement for a model explicitly called GPT-6.[1][4]
What is publicly documented instead is the GPT-5.x line, including GPT-5.6 (with tiers such as Sol, Terra, and Luna), which has been rolling out through ChatGPT and the API.[1][3] OpenAI’s official news/model pages currently highlight GPT-5.6-related updates rather than a GPT-6 launch.[2][3]
So the best current answer is:
GPT-6 release date: unknown / not announced.
There are some public signals that OpenAI is working on a “next major model” internally, but that does not amount to a confirmed GPT-6 schedule, and the naming itself may still change.[8] Until OpenAI publishes an official product announcement, any date would be speculation.

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.

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.
