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 the provider publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.

Kimi K2.5 pricing by host
A host is a company that runs the model and sells it by the token — the lab that made it, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent provider. One model, several sellers, and often several prices. This model is sold by 5 different hosts. The price quoted above is the one we publish so that models stay comparable; it is not necessarily the cheapest way to buy this model. List prices as published on 2026-09-28 via OpenRouter — negotiated rates, committed-use discounts and provisioned capacity are not shown.
The price we publish is already the cheapest of the 5 hosts: SiliconFlow at $0.45 input / $2.25 output per 1M tokens. It serves a quantized int4 build, which is not the same product as the full-precision model. The dearest, Venice, charges 1.5x the cheapest.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| SiliconFlow (the price shown above) — int4 | $0.45 | $2.25 |
| AtlasCloud — int4 | $0.49 | $2.50 |
| Novita | $0.57 | $2.85 |
| Amazon Bedrock | $0.60 | $3.00 |
| Venice | $0.53 | $3.33 |
