GPT 6 Release Date
GPT-6 began with Astra on September 3, 2026. Sol and Luna joined the family on September 22. Follow each announcement and its access changes.
The confirmed GPT 6 release date
The GPT 6 release date is September 3, 2026 for OpenAI’s public Astra announcement and initial limited rollout. The launch announcement described access expanding over the following days. Sol and Luna followed on September 22, 2026. An announcement date and an individual account’s activation date are different milestones.
The date and rollout wording come from OpenAI’s GPT-6 Astra: A new generation of intelligence, while the current ChatGPT product label is documented in OpenAI Help’s GPT-5.6 and GPT-6 Pro in ChatGPT.
How to access GPT-6 Astra today
- Chat: sign in to the intended account and check whether GPT-6 Pro appears for your eligible plan and workspace.
- Work or Codex: check that product’s model selection, allowance and current client version; access can differ from Chat.
- API: confirm the
gpt-6-astramodel is available to your API organization and project, with separate billing enabled.
Follow the step-by-step access guide for official entry points and missing-model checks. An eligible plan and the announcement date do not guarantee that every account has received access.
GPT 6 release timeline
| Date or stage | What the official source establishes | What to check next |
|---|---|---|
| September 3, 2026 | OpenAI announces GPT-6 Astra and begins limited rollout | Read the original announcement |
| Following days | Expansion is described across ChatGPT plans, the API, Azure and Bedrock | Check the specific product and account |
| September 22, 2026 | OpenAI launches Sol and Luna for Work, Codex and the API | Read the Sol/Luna launch record |
| September 23, 2026 | Codex CLI 0.156.1 adds Sol/Luna to its model picker | Update Codex |
| September 7 source check | Help Center distinguishes GPT-6 Pro in Chat from Astra in Work and Codex | Inspect the eligible plan and workspace settings |
There is no single universal account-activation time in the announcement. The ChatGPT access guide covers plan and workspace questions; the API guide covers the developer model identifier and account setup.
Which release milestone matters to you?
If you are writing about the launch, cite the September 3 announcement. If you are helping a teammate get access, record the product, plan, workspace and visible model label. If you are integrating an application, confirm the API organization can call the required model and tools. A screenshot of Codex cannot establish API access, and an API model page cannot establish a particular ChatGPT allowance.
The names also differ by surface. OpenAI Help describes GPT-6 Pro in ChatGPT as powered by Astra. Developers use gpt-6-astra, gpt-6-sol or gpt-6-luna. Preserve the exact name beside the observed date so an account check remains interpretable later.
What launched with Astra
OpenAI presents Astra as a model for demanding connected work, including browsing, computer use, software engineering and professional documents. Its launch demonstrations and customer reports describe particular evaluated tasks. Our practical examples pair original case context with smaller, inspectable site experiments.
Changes to a later Help Center page or API price do not move the original release date. They change the access or integration advice attached to it. The dated news record keeps those updates separate.
If the model is still missing
Check the product first: Chat, Work, Codex and API access have separate settings. Then check plan eligibility and rollout messages. In a managed workspace, ask the administrator to inspect model-access controls; Enterprise access was described as off by default at launch. For an API organization, keep the exact error and request ID when asking for support.
Do not buy an unrelated third-party offer just because it promises immediate access. Start with the official service and its current account information. The source links below identify the announcement, model reference and plan guidance used for this timeline.
