Why high: one template-boundary shift from a group whose members all declare the same family.
Kwaipilot: KAT-Coder-Pro V2 is Kwaipilot's model. Its measured tokenizer sits with the Qwen group, which is evidence that it builds on the Qwen tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against Kwaipilot's authorship of the model itself.
| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Counted cleanly, and no other model in the catalogue counts the same way | tk_e60ca14a |
| How its API is set up | A combination of settings no other listing in the catalogue uses | api_f460bcfd |
| How much it can read and write | Reads up to 262,144 tokens at once, writes up to 144,000 | its own listing |
| Who served our requests | AtlasCloud | we measured it, 21 August 2026 |

We sent Kwaipilot: KAT-Coder-Pro V2 fifty short pieces of text and recorded what each one cost it in tokens. The bars below are those costs. Two models built on the same tokenizer produce the same bars; a model built on a different one produces a different set, which is what makes this a fingerprint.
Overhead subtracted: 19 prompt tokens.
KAT-Coder-Pro V2 is the latest high-performance model in KwaiKAT’s KAT-Coder series, designed for complex enterprise-grade software engineering and SaaS integration. It builds on the agentic coding strengths of earlier versions,...

* Kwaipilot: KAT-Coder-Pro V2 no longer appears in the OpenRouter catalogue, first absent from the snapshot of 5 October 2026. The record stays because the measurements above were real when they were taken and this address has been published.
