What these states mean · How records are judged · Has this record changed?
OpenAI introduced GPT-6 Astra, which it describes as its most intelligent and aligned model and state of the art on computer use, browsing, software engineering, cybersecurity, science and professional work. It rolled out first to a limited set of organizations, with ChatGPT Plus, Pro, Business and Enterprise, the API, Azure and Bedrock to follow. OpenAI's own announcement page carries no date; the date here is the one OpenAI's news index prints against the accompanying safety overview and system card.
