SWE-Bench 1

AI-driven code intelligence models for software engineering and coding tasks. Kat Dev is an AI-driven code intelligence offering developed by Kuaishou's Kwaipilot team. It is a family of large language models specialized for software engineering and coding tasks, designed to act like AI engineers. Kat Dev models are capable of understanding complex requirements and generating high-quality code, achieving high performance on benchmarks like SWE-Bench. The models are high-parameter LLMs (32B or 72B) trained specifically for coding with state-of-the-art architectures and extensive reinforcement learning, including multi-stage agentic training with tool use, multi-turn dialogue, and coding knowledge.
