Input, output and cached input are the prices debited from your prepaid balance per 100,000 tokens, margin and VAT included. Context is the window as served on Frontière AI; max output is the provider's cap on max_tokens (— when it sets none we know of). Tool calling is measured with a real call per model.

How much does the Kimi API cost?
Kimi K3 costs €0.4536 per 100,000 input tokens and €2.268 per 100,000 output tokens on Frontière AI — margin and VAT included, that is the amount debited from your prepaid balance. The calculator on this page turns it into a monthly cost for your workload.
Which Kimi model has the largest context window?
Kimi K3, with 1M tokens of context as served on Frontière AI.
Is the Kimi API hosted in Europe on Frontière AI?
No. Kimi K3 is served by US providers, subject to the CLOUD Act even in an EU region: labeled fast access, never sovereign, and flagged by the API before you call.
Is there a subscription or a minimum spend?
No subscription. You top up a prepaid balance from €10 and each call is debited at the per-token price. Calls are refused once the balance reaches zero; a call already running can take it slightly below — deducted from your next top-up.
Do I need to change my code to call Kimi models?
No, if your code already uses an OpenAI SDK: point base_url at https://getfrontiereai.eu/api/v1, use a Frontière AI key and pass the model id, for example “kimi-k3”. Streaming and tool calling are relayed as-is.
How are cached input tokens billed?
Kimi K3 has a discounted rate for prompt tokens the provider serves from its cache (€0.0454 per 100k tokens on Kimi K3). The provider reports these tokens on each call and we bill them at that rate; on a model without a cache rate, every input token is billed at the input rate.
