Kimi K3.1 Pro is amongst the leading models in intelligence and reasonably priced when comparing to other models of similar price. It's also slower than average and very verbose. The model supports text and image input, outputs text, and has a 1M tokens context window.

Kimi K3.1 Pro scores 55 on the Artificial Analysis Intelligence Index, placing it well above average among comparable models (median: 27). When evaluating the Intelligence Index, it generated 150M tokens, which is very verbose in comparison to the median of 87M.

Pricing for Kimi K3.1 Pro is $2.00 per 1M input tokens (moderately priced, median: $2.00) and $10.00 per 1M output tokens (moderately priced, median: $10.00). On average, it costs $2.11 per task to evaluate Kimi K3.1 Pro on the Intelligence Index.

At 77 tokens per second, Kimi K3.1 Pro is slower than average (81).

Metrics are compared against models of the same class:

- Non-reasoning models → compared only with other non-reasoning models

- Reasoning models → compared across both reasoning and non-reasoning

- Open weights models → compared only with other open weights models of the same size class:

- Tiny: ≤4B parameters

- Small: 4B–40B parameters

- Medium: 40B–150B parameters

- Large: >150B parameters

- Proprietary models → compared across proprietary and open weights models of the same price range, using a blended 3:1 input/output price ratio:

- <$0.15 per 1M tokens

- $0.15–$1 per 1M tokens

- >$1 per 1M tokens
