# Configuration Reference

> Configure models, storage, installed tools, and agent access.

Open **Settings** to configure the active Larkup workspace. Changes apply to Chat, indexing, and the generated server.

## AI Models

Use **Settings → AI Models** to choose the provider and model for embeddings, chat, and vision.

The embedding model turns content and queries into vectors; changing it requires indexing existing content again. The chat model answers from retrieved context and can use a different provider than embeddings. The vision model powers video, image, and OCR tools and can also differ from the chat model.

## Storage and retrieval

Use **Settings → Storage** to choose Semantic, Lexical, or Hybrid retrieval and the storage engine. LanceDB runs from a local path, LanceDB Cloud, or S3 compatible storage; use a persistent remote mode before deploying to a serverless platform.

## General

Use **Settings → General** to name the workspace and set its theme.

Web search is configured separately under **Settings → Search & Scraping**, covered in [Web Crawl at Scale](/documentation/documentation/guide/data-loading).

## Installed tool settings

Marketplace tools add their own settings under **Settings → Installed Tools**.

## Agent tools

Use **Settings → Agent Customization** to control the prompt, tools, skills, MCP connections, and sandbox the assistant can use. See [Agent Server API](/documentation/documentation/developer/agent-runtime-api).

## Server configuration

After configuring models, storage, and tools, open **Settings → Larkup Server** to launch or deploy the API. See [Deploy Your Server](/documentation/documentation/developer/deploy).
