OpenAI expanded its Daybreak program with the GPT-5.5-Cyber model, focusing on closed-loop patch generation for cybersecurity, scanning over 30 million commits and covering major projects like cURL and Python. The release sparked debate on policy and export controls, contrasting with Anthropic's restricted Mythos/Fable access. Sakana Fugu introduced an orchestration API that learns model selection and delegation across multiple models, but faced criticism for opaque baselines and cost reporting. Meanwhile, GLM-5.2 is gaining attention as an open-weight model suitable for agentic applications and infrastructure adoption. "The notable shift is from 'find bugs' to closed-loop patch generation with human review" and "test-time coordination can beat monolithic calls on long-horizon tasks" highlight key technical insights.
