Kimi 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.

Kimi K3 は OpenAI 互換の Chat Completions API を提供します。任意の OpenAI SDK を EmpirioLabs API キーで https://api.empiriolabs.ai/v1 に向け、モデル ID kimi-k3 を使ってください。 EmpirioLabs ダッシュボードで API キーを取得してください。

| パラメータ | タイプ | デフォルト | 範囲 / 値 | 説明 |
|---|---|---|---|---|
| max_tokens | number | 32768 | 1 から 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.
EmpirioLabs では Kimi K3 は従量課金です: Input $3.00 per 1M prompt tokens; Output $15.00 per 1M generated tokens; Web search $0.015 per call when invoked。このページのライブ料金表は常に API の請求額と一致します。
Kimi K3 は 1M トークンのコンテキストウィンドウに対応しています(1回の応答あたり最大 131,072 出力トークン)。
はい。Kimi K3 は OpenAI 互換の Chat Completions API を提供しているため、既存の OpenAI SDK は base_url を https://api.empiriolabs.ai/v1 に向けてモデル ID を kimi-k3 に設定するだけで動作します。
はい。EmpirioLabs プレイグラウンドでは API と同じパラメーターで Kimi K3 をブラウザ上で実行できるので、コードを書く前にプロンプトを試せます。
EmpirioLabs アカウントを作成し、ダッシュボードの API Keysでキーを生成してください。課金は従量制クレジットなので、実行したリクエストの分だけ支払います。
