# Anthropic

Anthropic's Claude is currently the most suitable to use as [Cherry Agent](/docs/en-us/cherry-studio/preview/agent.md) one of the backend models, because the Agent requires an Anthropic protocol endpoint.

## Get an API Key

* Go to [Anthropic Console](https://console.anthropic.com/) Register account
* Enter `Settings → API Keys` → `Create Key`, copy the generated `sk-ant-...` Key

## Configure in Cherry Studio

* Open `Settings → Model Services`, find **Anthropic** Provider to enter the details page
* in **API key** and enter it in `sk-ant-...`
* **API URL** Default `https://api.anthropic.com`, no need to modify
* Click **Get model list**, add `claude-opus-4`、`claude-sonnet-4`、`claude-haiku-4` and other models

## Recommended usage

| Model             | Suitable scenarios                                                 |
| ----------------- | ------------------------------------------------------------------ |
| `claude-opus-4`   | Strongest reasoning / programming / complex Agent tasks            |
| `claude-sonnet-4` | General conversation and everyday Agents, the top choice for value |
| `claude-haiku-4`  | High-throughput scenarios, low-cost quick replies                  |

## Agent scenario configuration

Set this Provider in [Cherry Agent](/docs/en-us/cherry-studio/preview/agent.md) the configuration as the default model source, and you can directly obtain Anthropic protocol Agent capabilities.

{% hint style="info" %}

* Mainland China cannot directly access the Anthropic API; you need to prepare your own proxy (see [General settings → Proxy mode](/docs/en-us/pre-basic/settings/general.md))
* Users subscribed to Claude Code can also use the same key + endpoint to connect Cherry Studio
* Claude models are billed by token; please monitor usage for long contexts
  {% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cherryai.com.cn/docs/en-us/pre-basic/providers/anthropic.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
