About

SWE-1 is the first family of software engineering models developed by Windsurf, designed to optimize the entire software engineering process. Comprising three models—SWE-1, SWE-1-lite, and SWE-1-mini—this innovative family of models tackles more than just coding by supporting a wide range of engineering tasks. SWE-1 outperforms other models, providing powerful, multi-surface, long-horizon task management and AI-driven insights that significantly accelerate software development. This groundbreaking approach allows for more efficient problem-solving and an AI-powered workflow that integrates seamlessly with user actions.

About

SWE-1.7 is Cognition’s frontier software engineering model designed to deliver high intelligence at a lower rollout cost. The model is optimized for long-horizon agentic coding tasks, including debugging, feature implementation, codebase exploration, migrations, terminal workflows, and multilingual software engineering. SWE-1.7 was trained from a Kimi K2.7 base using large-scale reinforcement learning improvements across infrastructure, data quality, training stability, self-compaction, and long-running task execution. It is built to explore codebases thoroughly, probe edge cases, identify hidden requirements, and produce more complete end-to-end solutions. The model is available in Devin across web, desktop, and CLI through Cerebras at very high serving speeds. SWE-1.7 is positioned for developers and engineering teams that need cost-efficient frontier-level coding intelligence for complex real-world software work.
