Answer from Jul 23See the current answer
Short answer: OpenAI has not announced a release date for GPT-6. As of the latest official information, there is no confirmed launch window and no official product page, API entry, or release note naming GPT-6.
What OpenAI has publicly released and discussed instead is the GPT-5.6 family, including the “Sol,” “Terra,” and “Luna” variants, which was announced and then rolled out in mid-2026.[1][4]
OpenAI’s research index and API docs currently point to GPT-5.x-era models, not GPT-6.[2][3] OpenAI has also referred to a more capable pre-release model in a security-related post, but that does not establish a GPT-6 name or date.[5]
Bottom line: there is no reliable public date for GPT-6 yet. The first trustworthy signal will likely be an official OpenAI announcement or model listing that explicitly says “GPT-6.”

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.
