KAT-Coder-Pro V2 vs Qwen3 Coder 480B A35B: which should you choose in 2026?

KAT-Coder-Pro V2 (by KwaiPilot) and Qwen3 Coder 480B A35B (by Qwen) are compared below. Here is how they stack up on benchmarks, price, and capabilities, and which one to pick in 2026.

There are not enough shared, protocol-compatible benchmark results to declare a performance leader.

Qwen3 Coder 480B A35B is about 1.1× cheaper on a blended 3:1 input/output basis ($0.475 vs $0.525 per 1M tokens).

Choose KAT-Coder-Pro V2 if…

  • • your own prompt tests favor its output; shared comparable evidence does not identify a unique advantage

Choose Qwen3 Coder 480B A35B if…

  • • lower blended API cost matters for your workload

The benchmark count includes only results measured with a matching benchmark version and protocol. Arena scores are shown separately. Missing, preliminary, and incompatible data is not treated as a controlled win. Published point-score comparisons are labeled separately when protocol details are incomplete. For text-output models, the verdict also compares token pricing and context windows.
