Mini toolsKAT Coder
KAT-Coder is the flagship model in Kwaipilot’s KAT series for complex software engineering tasks. According to the project page, it builds on mid-training, SFT, reinforcement fine-tuning, and large-scale agentic RL, with training data covering tool use, long multi-turn dialogues, coding knowledge, PR data, and real delivery trajectories from engineers. The page highlights emergent behaviors after RL scaling, including fewer interaction turns and parallel tool calling, and reports 73.4% on SWE-Bench Verified. It is positioned as the highest-performance variant, available through API access rather than as the open release.

Overview
KAT-Coder is Kwaipilot’s strongest code intelligence model, designed for advanced software engineering and agentic coding workflows. It is trained with the same staged pipeline as KAT-Dev but pushes further on agentic RL, tool use, multi-turn software tasks, and efficient problem solving, with the project page highlighting stronger SWE-Bench Verified performance than the open model.
