OpenAI made GPT-6 Astra available to all Pro, Enterprise, and Business Premium users and through its API.

OpenAI chief executive Sam Altman said GPT-6 Astra was available to all Pro, Enterprise and Business Premium users. He also said the model was available through OpenAI’s application programming interface, or API.

A separate OpenAI update described access through ChatGPT Work and Codex for users in those subscription categories. The source did not provide API prices, context-window size, benchmark results or model architecture details.

Altman said OpenAI would next begin expanding access to Plus and Business users. That statement described the next rollout stage; the supplied sources did not state that access for those two tiers was already complete.
