GPT-6 Astra reaches the $20 ChatGPT Plus tier after a rollout Altman had to apologize for
OpenAI
Following up on the Sep 3 flagship launch: on Sep 6, 2026 OpenAI began rolling GPT-6 Astra out to $20 ChatGPT Plus subscribers; an OpenAI X post confirmed availability 'to all Pro, Enterprise, and Business Premium users in ChatGPT Work and Codex. It's also live in the API.' The rollout to paying users was delayed days after launch, prompting a public apology from Sam Altman for the 'messy' release; free users still only have GPT-5.6 Sol and GPT-5.
