When was GPT-6 released, and which GPT-6 models can you use today?
OpenAI has not released “GPT-6” as one single model on one single date. It appears to have rolled out the GPT-6 family in stages.

Timeline
GPT-6 rollout
- GPT-6 Astra announcement and initial rolloutfirst GPT-6 announcement and initial rollout
- GPT-6 Sol and GPT-6 Luna
- GPT-6.1 Sol
- Broader ChatGPT rollout for paid users
- Broader ChatGPT rollout for Free and Go users
The first GPT-6 announcement and initial rollout was September 3, 2026, with GPT-6 Astra.
After that, OpenAI expanded the family with:
- GPT-6 Sol and GPT-6 Luna on September 22, 2026
- GPT-6.1 Sol on September 29, 2026
- A broader ChatGPT rollout starting October 7, 2026 for paid users, and October 8, 2026 for Free and Go users
So the safest answer is: GPT-6 began releasing on September 3, 2026, and the family was expanded through October 2026.

Practical takeaway
- If you mean ChatGPT, the model you see depends on your plan and rollout status.
- If you mean the API, the currently documented GPT-6 family includes Astra, Sol, Luna, and GPT-6.1 Sol, though exact access can vary by account and surface.
- If you don’t see a GPT-6 option yet, that can simply mean it hasn’t fully rolled out to your account.
Bottom line
GPT-6 first released on September 3, 2026.
Today, the usable GPT-6 models are Astra, Sol, Luna, and GPT-6.1 Sol, subject to plan and access limits.

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 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.
