Our take
Written Sep 2, 2026KAT-Coder-Pro V2 is Kwaipilot's proprietary coding model built for long-context code tasks, handling up to 262,144 tokens in a single request. It is available through three providers at identical rates, though no benchmark scores have been measured yet.
Pick this when you need a quarter-million tokens of context for code repositories or long documents, and want predictable costs across providers. Use it for budget-predictable coding tasks where you can choose your host. Skip it if you need measured quality data, open weights, or faster throughput than 14 tokens per second.
The case for it
- Identical pricing across all three tracked providers removes cost-comparison friction.
- 262,144-token request limit fits substantial codebases and long documents.
The case against it
- No benchmark scores in our data, so the 'Pro' coding claim is unverified.
- Throughput is modest: 14 tokens per second at the fastest provider, 11 at another.
- Proprietary weights with no open licence; you cannot self-host or inspect the model.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.

Across the 3 listings we hold: 2 say they do not train on prompts, 0 say they do and 1 does not say. 0 appear in the zero-retention registry we check; the rest are unknown to us.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- No independent board has scored it, so we hold no quality figures at all.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 1 of 3 listings does not say whether it trains on prompts.
- We don't hold a list price for this model yet — the gap is ours, not the lab's.
- We hold no batch or off-peak rate for any of its listings.
