OpenAI begins rolling out Astra model after warning of its advanced cyber capabilities

OpenAI says the model reaches its highest cyber risk tier and will first go to businesses as it adds stronger monitoring and shutdown safeguards.

  • On Thursday, OpenAI unveiled GPT-6 Astra, featuring advanced computer use and coding capabilities, with a phased rollout beginning through the Daybreak program and expanding to ChatGPT and API users in coming days.
  • Following a July security incident at Hugging Face, OpenAI implemented stronger safeguards and designated Astra as its first model crossing the 'Critical' cybersecurity threshold under the Preparedness Framework.
  • Astra achieved a 100% score on ExploitBench and 99.9% on ARC-AGI-3, marking significant performance gains over GPT-5.6 Sol and demonstrating advanced technical reasoning across cybersecurity and abstract problem-solving.
  • Responding to Congressional scrutiny following the breach, OpenAI told U.S. House Democrats this week it is developing 'automated shutdown capabilities' to mitigate risks from agentic AI operating autonomously.
  • OpenAI President Greg Brockman hailed the 'AGI era,' though critics caution the term remains poorly defined while the company competes fiercely against Anthropic for enterprise market share.
