Astra

Astra is OpenAI's first model to trigger the 'Critical' cybersecurity threshold under its Preparedness Framework — internal evaluations found it may autonomously exploit zero-day vulnerabilities and solved 10 open math problems for ~$2,000. But Astra is not a shipping product: development is actively paused as of August 2026 for security hardening, with no release timeline or pricing. Watch for the safety-governance outcome — this is the first time a major lab has publicly classified its own model as critically dangerous.
