kat dev

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.

How to Use

To get started with Kat Dev, first download either the KAT-Dev-32B or KAT-Dev-72B-Exp model from Hugging Face. Next, integrate the model with your workflow using the Transformers library or vLLM for local deployment, or access KAT-Coder via the StreamLake console for enterprise-grade API access. Once integrated, you can start AI coding to generate code, fix bugs, implement features, and optimize performance. For scaling, deploy Kat Dev models in production environments, integrate with CI/CD pipelines, and build custom AI coding assistants for your team.
