Multimodal Kimi model with 1M context and always-on reasoning for coding, 3D creation, financial research, and agentic work
Kimi K3.1 Pro by moonshotai is offered by 19 providers on this page. Public prices are shown for 15 of them. Its official list price is $2.00 per 1M input tokens and $10.00 per 1M output tokens. Prices vary about 2.1× across the providers that host it. It also has 4 covered by a paid subscription; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
Artificial Analysis rates it 55.1 on the Intelligence Index. Against its lowest blended price of $4.00 per 1M, that is roughly 14 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 77 tokens per second, with 2.89s to the first token. Running one task of the Artificial Analysis suite costs about $2.1145, which reflects how many tokens its reasoning consumes rather than the unit price alone.
The context window is 1,048,576 tokens at the reference host, but hosts report different limits, from 1,000,000 to 1,048,576, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, and Video.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.
