OpenAI begins a phased rollout of GPT-6 Astra, giving cybersecurity-program participants first access

Sources: CNBC, discussion, second thread
Summary: CNBC reports the rollout is phased, that a limited group of companies participating in OpenAI's application-based Daybreak cybersecurity program gets access first, and that plan and API availability follow. The report quotes OpenAI President Greg Brockman from a press briefing, and states OpenAI rated the model at its Critical internal cybersecurity threshold. The openai.com post for the release returned HTTP 403 to automated fetch, so this is carried on the secondary rather than on OpenAI's own page.
Why it matters: The model OpenAI rated at its Critical internal cybersecurity threshold now ships, and the first access tier is an application-based program rather than general availability.
Follow-up: Track when Astra reaches general availability on plans and the API, and whether OpenAI's own post becomes reachable.
