The New Stack 1 month ago 18

OpenAI’s unreleased Astra model is running inside the company’s codebase and converting experiment ideas into code, execution, and results without step-by-step human prompting. OpenAI says monitoring Astra’s tool use adds about 20% to inference compute, and Astra may have reached the “Critical” cybersecurity capability threshold. OpenAI has tightened controls, resumed only some workloads, and continues work on safer infrastructure while highlighting new governance and cost needs for developers using long-running agentic coding systems.
