# Response Modes

> Choose how the AI assistant processes your requests for optimal speed and accuracy.

Omnifact offers different **Response Modes** to give you control over how the AI assistant handles your queries. Whether you need a quick answer, a comprehensive analysis using all available tools, or a strict lookup from your internal documents, you can select the mode that best fits your current task.

## Available Modes

There are three response modes available in the chat interface:

### Auto Mode (Default)

This is the most powerful mode and is selected by default. In **Auto** mode, the AI "thinks" more about your request and autonomously decides which tools to use.

* **Capabilities:** Can [search the web](/en/platform/core-features/chats/web-search-browsing), retrieve documents from your [Knowledge Base](/en/platform/core-features/spaces/knowledge-base-retrieval), [generate images](/en/platform/core-features/chats/image-generation), and fetch URLs.
* **Best for:** Complex questions, research, tasks requiring up-to-date information from the web, or when you're unsure which mode to use.

### Quick Response

**Quick Response** is designed for speed. The AI answers directly from its internal training data without using any extra tools (like web search or document retrieval).

* **Capabilities:** Fast text generation only. No web search or Knowledge Base access.
* **Best for:** General knowledge questions, brainstorming, drafting emails, or when you need an immediate answer without waiting for tool processing.

### Simple Lookup

**Simple Lookup** focuses exclusively on your internal data. It forces the AI to answer *only* using the information found in the Space's Knowledge Base without any web search or other tools.

* **Capabilities:** Retrieves information strictly from uploaded documents. No web search or other tools.
* **Best for:** Answering specific questions about company policies, technical specifications, or any query where you want to avoid "hallucinations" or outside information.
* **Note:** This mode is only available in Spaces that have a Knowledge Base with documents uploaded.

## Switching Modes

You can change the response mode at any time before sending a message. The selected mode applies to the next message you send.

<Tip>
  You can even switch modes for a previous message! On any AI response, look for the **Response Mode** dropdown to regenerate the answer using a different mode. This is great for comparing how different modes handle the same question.
