KAT Coder Pro V2 is a flagship agentic coding model developed by Kwaipilot, the AI research division of Kuaishou Technology. Released in March 2026, the model is specifically engineered for enterprise-grade software engineering, SaaS integration, and complex agentic workflows. It represents a significant advancement in the KAT-Coder series, transitioning from standard code generation to autonomous reasoning and multi-system coordination within production-scale development environments.
The model utilizes a sparse Mixture-of-Experts (MoE) architecture, reportedly featuring 72B active parameters out of a larger total parameter count. It supports a native 256,000-token context window, enabling it to process entire repositories and multi-file projects in a single prompt. On the SWE-Bench Verified benchmark, KAT Coder Pro V2 achieved a solve rate of 79.6%, positioning it among the leading code generation models globally for solving real-world software issues.
A key technical highlight is the model's "Specialize-then-Unify" training paradigm. During development, five specialized expert domains—including Software Engineering (SWE), Web Coding, Terminal operations, Web Search, and General knowledge—were trained independently and subsequently consolidated via on-policy distillation. This approach allows the model to maintain specialized precision across a variety of developer tasks, from low-level debugging to high-level architectural planning.
Beyond logic-based programming, KAT Coder Pro V2 features advanced capabilities in frontend aesthetic generation. It is designed to produce production-grade landing pages and UI components from natural language descriptions without requiring structured design specifications. The model is optimized for tool use and function calling, facilitating native integration with various AI coding scaffolds for autonomous execution across modern software stacks.
