OpenAI classifies GPT-6 Astra as 'Critical' for cybersecurity; Microsoft makes it generally available in Foundry

OpenAI has classified GPT-6 Astra at the Critical level for cybersecurity under its Preparedness Framework, saying expert-led tests showed the model autonomously discovered multiple previously unknown vulnerabilities and developed end-to-end exploit chains against a browser and an OS kernel. Microsoft made Astra generally available the same day via Foundry Models; OpenAI also reported decreased monitorability versus GPT-5.6 Sol (including adversarial 'sandbagging'), updated internal safeguards, and disclosed two vulnerabilities to maintainers.

GitHub rewrote the Copilot agent runtime in Rust with Copilot agents

GitHub migrated the Copilot agent runtime from a TypeScript/Node.js/V8 implementation to over 800,000 lines of production Rust. Most of the Rust code was authored by AI agents via the GitHub Copilot app and CLI across 128 pull requests; the migration shipped incrementally, reportedly improving runtime performance by orders of magnitude and reducing startup and memory overhead for many Microsoft/GitHub products that share the runtime via the Copilot SDK.

It highlights a pattern where companies that profit from AI nevertheless urge intervention, often without resulting in substantive policy changes.
