Moonshot AIGeração de Texto1M contextoLançado 15 de jul. de 2026InternationalEndpoint proprietárioNovoKimi K3 is Moonshot's flagship reasoning model with a 1M token context, always-on thinking, native web search, and text, image, and video inputs.
Supports text, image, and video inputs, function calling, JSON schema structured output, and built-in web search billed at $0.015 per invoked call. Thinking is always on with a tunable reasoning_effort control (max recommended); reasoning tokens are billed as output tokens. Temperature and other sampling overrides are fixed by the model service. Multi-step function calling must replay the assistant message with its reasoning_content field intact. Explicit cache controls, batches, and fine-tuning are not supported.

| Parâmetro | Tipo | Padrão | Intervalo / valores | Descrição |
|---|---|---|---|---|
| max_tokens | number | 32768 | 1 a 1048576 | Maximum output tokens. Reasoning tokens count toward this limit. |
| stop | string | - | - | Up to 4 strings where the model will stop generating further tokens. |
| reasoning_effort | enum | max | low, medium, high, max | Kimi K3 reasoning effort. Thinking is always on. Higher effort spends more reasoning tokens before answering. Max is recommended and the default. |
| tool_web_search | boolean | false | - | Search the web for real-time information. Adds $0.015 to the request cost for each invoked web search call. |
| response_format | enum | - | - | Constrain the output to JSON. Use JSON mode for any valid JSON object, or JSON schema to force output that matches a schema you provide. |
Supports text, image, and video inputs with a 1M token context, function calling, JSON schema structured output, and built-in web search at $0.015 per invoked call. Thinking is always on; reasoning depth is tunable with the reasoning_effort control (max is recommended) and reasoning tokens are billed as output tokens. Temperature and other sampling settings are fixed by the model service. Multi-step function calling through the API must replay the assistant message with its reasoning_content field intact.
When this model invokes built-in tools inside a single request, the response carries a normalized usage.tool_usage map alongside the token counts. Tool counts are already factored into cost_usd and are surfaced for transparency.
Na EmpirioLabs, Kimi K3 é cobrado por uso: Input $3.00 per 1M prompt tokens; Output $15.00 per 1M generated tokens; Web search $0.015 per call when invoked. A tabela de tarifas ao vivo desta página sempre corresponde ao que a API cobra.
Kimi K3 suporta uma janela de contexto de 1M tokens com até 131.072 tokens de saída por resposta.
Sim. Kimi K3 atende a API Chat Completions compatível com OpenAI, então SDKs OpenAI existentes funcionam apontando base_url para https://api.empiriolabs.ai/v1 e definindo o id de modelo kimi-k3.
Sim. O playground da EmpirioLabs executa Kimi K3 no navegador com os mesmos parâmetros que a API expõe, para você testar prompts antes de escrever código.
