KAT-Coder-Pro V2

model

Kwaipilot's 2026 agentic-coding refresh of the KAT-Coder line. <strong>AA Intelligence Index v4.1: 34</strong> (non-reasoning). Base undisclosed; the KAT line is post-trained from external pretrained bases (Kwaipilot's own pipeline description is "fine-tuned a pretrained model", the open V1 sibling KAT-Dev-72B-Exp is architecturally Qwen2.5-72B, and the open V2.5 sibling is built on Qwen3.6-35B-A3B).
