OpenAI's GPT-6 Astra is the first model rated Critical for cyber, Nvidia acquires Hugging Face for $12.93B, Google gates Gemini 3.8 Flash Cyber, and Meta returns to the frontier.

OpenAI says Astra is considerably more capable at cyber tasks than GPT-5.6 Sol. Following the Hugging Face incident, it is being especially cautious about releasing it.

The company will give select partners early access to its Astra AI model—so they have time to shore up their defenses.
