OpenAI's GPT-6 goes to a few firms first. Will free users get it by 18 September?

What happened

OpenAI announced GPT-6 Astra on Thursday as the world’s most intelligent and aligned model, launching first with a limited set of organisations and promising general availability in the coming days.

Bloomberg reported the order of the rollout. First come companies in OpenAI’s cybersecurity programme, which firms apply to join. Then come the paid ChatGPT plans: Plus, Pro, Business and Enterprise. After that, developers get it through the API, the service that lets other software use the model, and through Amazon Web Services.

Free ChatGPT users are not on that list. OpenAI did something similar in July. At the White House’s request it gave GPT-5.6 to a small group of US organisations on , then released it to the public on , thirteen days later.

Astra’s own training was paused in August under OpenAI’s safety rules, called the preparedness framework, after the Hugging Face incident.

So the open question is when free users get Astra. OpenAI has launched past versions in two ways. Sometimes paid users came first and free users waited weeks or months. Sometimes free users got the model at launch or within days, when the company wanted many users at once. We check whether free users had a model of the version within 15 days, which for Astra means by .

The Pattern

Five of the last eight GPT versions reached free users in 15 days. We looked at every GPT version launched in ChatGPT since GPT-4o in where an OpenAI page or a report from our approved sources said who could use it and when. For each one we asked if free ChatGPT users had a model of that version within 15 days of the announcement.

5 of 8
Five of the last eight GPT versions with a traceable rollout reached free ChatGPT users within 15 days of their announcement: GPT-4o and GPT-5 on day one, GPT-5.3 Instant on day one, GPT-5.5 after twelve days and GPT-5.6 with its Terra tier at public launch. GPT-4.5, GPT-4.1 and GPT-5.4 stayed behind paid plans. Adding GPT-4 in March 2023 makes it five of nine. GPT-5.1 and GPT-5.2 are left out because no whitelisted page reachable at the rework states when free users received them.

The Read

History leans towards free users getting some form of Astra within the two weeks, but only just. Five of the last eight versions reached free users in time. The closest example, GPT-5.6, went from a limited preview for cyber security work to a public launch with a version for free users in thirteen days.

The doubt is in the announcement itself. It lists every paid plan and the API, and it does not list the free plan. GPT-4.5, GPT-4.1 and GPT-5.4 launched the same way, and none of them reached free users within 15 days.

OpenAI has given free access before to answer a rival’s launch, and even a free version with tight usage limits would count. Free users miss out if the version with extra safety limits described for paid users is the only public one, or if the safety review that paused Astra in August pushes the stages past . The same delay would hit the Plus and API questions one step earlier.
