- R · What Makes It Special
- KAT-V1-40B (Kwaipilot-AutoThink), Kuaishou's open-weight 40B language model built to curb over-thinking: it judges each query and either reasons step by step or answers directly, trained with multi-token-prediction distillation and Step-SRPO reinforcement learning. Kuaishou reports it matching or beating DeepSeek-R1-0528 and Qwen3-235B-A22B on reasoning tasks with fewer tokens and leading open models on LiveCodeBench Pro; it runs in Kuaishou's Kwaipilot coding assistant.
