kat dev

Writing high-quality code at scale is hard — complex requirements get lost in translation, and most AI coding tools feel like glorified autocomplete. Kat Dev is different. Developed by Kuaishou's Kwaipilot team, it's an AI-driven code intelligence family of large language models (32B and 72B parameters) specifically trained for software engineering and coding tasks. These models are designed to act like AI engineers — capable of understanding complex requirements, generating high-quality code, and achieving top performance on benchmarks like SWE-Bench. Built with state-of-the-art architectures, extensive reinforcement learning, multi-stage agentic training with tool use, multi-turn dialogue, and deep coding knowledge, Kat Dev represents what truly engineering-grade AI looks like.
