Market position
On blended price ($2.4871 per 1M tokens at 30% input, 70% output) it is cheaper than 68% of models in the Mid-range price tier: 37th cheapest of 113. Across every price tier it is cheaper than 35% of priced text models in the catalogue: 197th cheapest of 303. Its Arena ELO of 1445 ranks 44th of the 160 models that carry one, tied with 2 others, above 72% of them. With an Arena score of 1445, Kimi K2.5 clears OptimNow's Standard working quality threshold: Standard (Arena 1420+), used for meeting summary, invoice processing and call summary. Each threshold is a distance below the best ranked model, which scores 1530 on Arena scores as of 8 Nov 2026.
Licence, size and capabilities
Kimi K2.5 is open weights, which is not the same as open source: the weights are published, but under Modified MIT, a licence that restricts some uses. Read it before self-hosting commercially. Its published size is 1T parameters. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 262K context window once costs $0.1394 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 5 different hosts. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
Cheapest host: AtlasCloud at $0.49 input / $2.50 output per 1M tokens, 24% below the price we quote on the blended price (30% input, 70% output). It serves a quantized int4 build, which is not the same product as the full-precision model. A support ticket workload at 100K requests a month costs $198.50 there against $246.05 at the price we quote, a difference of $47.55 a month. The dearest, Venice, charges 1.3x the cheapest.

Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where Moonshot publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.
