Kimi K3 API pricing
The Kimi K3 API pricing uses a token-based model, with usage billed per 1M tokens (1,000,000 tokens) for both input and output processing, enabling clear and predictable cost control.
| Model | Unit | Input Price (Cache Hit) | Input Price (Cache Miss) | Output Price | Context Window |
|---|---|---|---|---|---|
| kimi-k3 | 1M tokens | $0.30 | $3.00 | $15.00 | 1,048,576 tokens |
Kimi K3 is Kimi's flagship model for long-horizon coding and end-to-end knowledge work. It always reasons, with reasoning effort set through the top-level reasoning_effort field. The model supports automatic context caching, tool calls, JSON mode, structured outputs, and a full 1M-token context window in a single request.
How Kimi K3 API billing works
Kimi K3 API uses a token-based pricing model for each request, where every interaction with the model consumes tokens that are billed according to their type. Within this model, tokens are generally categorized into three types: input tokens, cached input tokens, and output tokens.
Input tokens
Input tokens represent everything sent to the model, including:
User prompts
System instructions
Conversation history or context These tokens determine how much context the model needs to process before generating a response. With a 1M-token context window, Kimi K3 can take in entire codebases, long documents, and extended multi-turn histories in one request.
Cached input tokens
Cached input tokens occur when previously processed context is reused.
If the same or similar context is reused, it is billed at $0.30 per 1M tokens instead of $3.00, a 90% reduction
This significantly improves efficiency for repetitive workflows
It is especially useful in long-context applications and multi-turn interactions, where large shared context is sent repeatedly
Output tokens
Output tokens are generated by the model in response to a request. They represent the actual AI-generated content, such as:
Text responses
Code generation
Structured outputs Because output generation requires additional computation, it is typically priced higher than input tokens.
Conclusion
Kimi K3 offers flexible pricing for everyday users and developers alike: membership plans for the full Kimi experience, and a token-based API with automatic context caching that cuts input costs by 90%. Choose the path that fits your workflow, and start with Kimi K3 today.
