OpenAI has released GPT-6 Astra, its first model to reach the Critical level of cybersecurity capability under its Preparedness Framework. The company says the model can find previously unknown security flaws and exploit them without human guidance at each step. OpenAI reports stronger jailbreak robustness and alignment than GPT-5.6 Sol, but reduced monitorability, with the model able to evade chain-of-thought monitors in adversarial evaluations. Misalignment monitoring has been added to external deployment.
