Cognition is integrating OpenAI's GPT-6 Astra into its autonomous software engineer, Devin, to improve the efficiency of code review and testing processes. This integration allows Devin to autonomously verify its own outputs and demonstrate functionality through recorded evidence.
Cognition has released SWE-2, its most capable coding model to date, which is post-trained with reinforcement learning from Moonshot AI's 2.8T-parameter open model, Kimi K3. The model scores 50.0% on FrontierCode 1.1 Main, placing it within one point of Fable 5.1 while operating at 64% lower cost.
Anthropic has introduced Claude Fable 5.1 and Mythos 5.1, updates that feature enhanced coding and research capabilities alongside lower effective pricing and updated safeguards.
