+description: Using LLMs from Anthropic (Claude)
+---
+
+# Anthropic (Claude)
+
+1. Create an account on [Anthropic](https://www.anthropic.com/) and get your API key from the [Anthropic Console](https://console.anthropic.com/settings/keys).
+
+2. Add the following to your `taskweaver_config.json` file:
+
+```json showLineNumbers
+{
+  "llm.api_type": "anthropic",
+  "llm.api_base": "https://api.anthropic.com/v1/messages",
+  "llm.api_key": "YOUR_API_KEY",
+  "llm.model": "claude-3-opus"
+}
+```
+
+:::tip
+`llm.model` is the model name you want to use. You can find the list of available Claude models in the [Anthropic API documentation](https://docs.anthropic.com/claude/reference/selecting-a-model).
+:::
+
+:::info
+Anthropic's Claude API doesn't have a specific `response_format` parameter like OpenAI. If you need structured output, you should instruct Claude to respond in a specific format (e.g., JSON) within your prompts.
+:::
+
+:::caution
+Anthropic doesn't provide a native embedding service. If you need embeddings, you'll need to configure a different service for that functionality.
+:::
+
+3. Start TaskWeaver and chat with TaskWeaver using Claude.
+   You can refer to the [Quick Start](../quickstart.md) for more details.
+
+Remember to replace `YOUR_API_KEY` with your actual Anthropic API key.
