Thinking Kimi model for slower research passes, planning, and hard technical questions
Kimi K2 Thinking by moonshotai is offered by 21 providers on this page. Public prices are shown for 19 of them. Its reference price is $0.60 per 1M input tokens and $2.60 per 1M output tokens. The lowest paid channel is Vercel AI Gateway at $0.47 / $2.00 per 1M, about 1.5× below the reference price.
Artificial Analysis rates it 22 on the Intelligence Index. Against its lowest blended price of $0.853 per 1M, that is roughly 26 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 158 tokens per second, with 1.32s to the first token.
The context window is 262,144 tokens at the reference host, but hosts report different limits, from 32,768 to 262,144, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2024-08.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
