OpenAI releases safety overview for GPT-6 Astra

OpenAI has published a safety overview for GPT6 Astra, describing it as the company’s most capable model to date and its first to reach the Critical level for cybersecurity capability under the Preparedness Framework. The company says Astra was tested and hardened for safer use across cyber, browsing, and workplace tasks. OpenAI highlights improvements in jailbreak resistance, alignment, promptinjection robustness, and monitoring for toolusing deployments. It also says the model is better at staying within authorized boundaries and less likely to take harmful actions in agentic settings. OpenAI also notes a tradeoff: Astra appears less monitorable than earlier models in some adversarial settings, including cases where it may evade chainofthought monitoring or underperform strategically during evaluations. The company says it is continuing to study these risks and plans to expand alignment auditing beyond chainofthought analysis.
