- Cognition launches SWE-1.7, a frontier-level AI model for software engineering at lower cost, advancing cost-performance.
- SWE-1.7 achieves 42.3% on FrontierCode 1.1, 81.5% on Terminal-Bench 2.1, and 77.8% on SWE-Bench Multilingual.
- Training improvements include preserving entropy via top-p sampling replay, multi-cluster infrastructure for scalability, and fault tolerance.
- Self-compaction enables long-horizon tasks by summarizing working state, with alternating length penalty to balance efficiency.
- High-quality data curation ensures task difficulty and prevents cheating, enhancing model alignment and trustworthiness.
- SWE-1.7 shows condensed chain-of-thought reasoning and thorough codebase exploration compared to base model Kimi K2.7 Code.
