## Model inference features

### Model capabilities

| Feature | Description |
| - | - |
| [Thinking models](https://platform.kimi.ai/docs/guide/use-thinking-models.md) | Use reasoning for complex tasks, multi-step tool calls, and agent workflows, while preserving reasoning content correctly across conversation turns. |
| ↳ [Reasoning effort](https://platform.kimi.ai/docs/guide/use-reasoning-effort.md) | Adjust reasoning depth, latency, and token usage with the levels supported by each model. |
| [Multi-turn conversations](https://platform.kimi.ai/docs/guide/engage-in-multi-turn-conversations-using-kimi-api.md) | Maintain message history and control context length with a stateless API. |
| [Streaming output](https://platform.kimi.ai/docs/guide/utilize-the-streaming-output-feature-of-kimi-api.md) | Receive incremental responses over SSE to reduce time to first token and process output as it arrives. |

| [Partial Mode](https://platform.kimi.ai/docs/guide/use-partial-mode-feature-of-kimi-api.md) | Continue a given assistant prefix, fix the opening of a response, or resume truncated output. |
| [Context caching](https://platform.kimi.ai/docs/guide/context-caching.md) | Reuse repeated request prefixes and reduce input costs with a 5m or 1h cache TTL. |

### API formats

| Feature | Description |
| - | - |
| [Chat Completions API](https://platform.kimi.ai/docs/api/chat.md) | Use the OpenAI-compatible format for conversations, structured output, and tool calling. |
| [Responses API](https://platform.kimi.ai/docs/api/responses.md) | Use the OpenAI Responses-compatible format to generate text or JSON and call function tools or server-side web search. |
| [Messages API](https://platform.kimi.ai/docs/api/messages.md) | Call Kimi with the Anthropic Messages-compatible format through tools such as the Anthropic SDK and Claude Code. |

### Tool calling

| Feature | Description |
| - | - |
| [Custom tool calling](https://platform.kimi.ai/docs/guide/use-kimi-api-to-complete-tool-calls.md) | Define function tools, execute model-requested calls in your application, and return the results to the model. |
| ↳ [Tool choice](https://platform.kimi.ai/docs/guide/use-tool-choice.md) | Use `tool_choice` to let the model select tools automatically, require a call, or disable tool use. |
| ↳ [Dynamic tool loading](https://platform.kimi.ai/docs/guide/use-dynamic-tool-loading.md) | Append tool definitions on demand to reduce token usage and preserve prefix caching. |
| ↳ [Kimi K3 tool calling best practices](https://platform.kimi.ai/docs/guide/kimi-k3-tool-calling-best-practice.md) | Design tool workflows with dynamic loading, `tool_choice`, and reasoning effort. |
| [Official tools](https://platform.kimi.ai/docs/guide/use-official-tools.md) | Configure and call official Kimi Open Platform tools through the Chat Completions API. |
| [Web search](https://platform.kimi.ai/docs/guide/best-practices-for-web-search.md) | Choose a search API, control costs, and improve queries and parameters for your scenario. |
| ↳ [Web Search Basic](https://platform.kimi.ai/docs/api/tools-search.md) | Get structured search results such as page titles, summaries, sites, and URLs through a standalone endpoint. |
| ↳ [Web Search Pro](https://platform.kimi.ai/docs/api/tools-search-pro.md) | Get relevance-ranked content chunks and restrict results by site and time range. |
| [URL Fetch](https://platform.kimi.ai/docs/api/tools-fetch.md) | Fetch the title and Markdown body of a specified web page. |
