Claude Code is Anthropic's agentic coding tool that can read, modify, and execute code in your working directory. 

Open models can be used with Claude Code through Ollama's Anthropic-compatible API, enabling you to use models such as `glm-4.7`, `qwen3-coder`, `gpt-oss`.

## Install

Install [Claude Code](https://code.claude.com/docs/en/overview):

<CodeGroup>

```shell macOS / Linux
curl -fsSL https://claude.ai/install.sh | bash
```

```powershell Windows
irm https://claude.ai/install.ps1 | iex
```

</CodeGroup>

## Usage with Ollama

### Quick setup

```shell
ollama launch claude
```

To configure without launching:

```shell
ollama launch claude --config
```

### Manual setup

Claude Code connects to Ollama using the Anthropic-compatible API.

1. Set the environment variables:

```shell
export ANTHROPIC_AUTH_TOKEN=ollama
export ANTHROPIC_API_KEY=""
export ANTHROPIC_BASE_URL=http://localhost:11434
```

2. Run Claude Code with an Ollama model:

```shell
claude --model gpt-oss:20b
```

Or run with environment variables inline:

```shell
ANTHROPIC_AUTH_TOKEN=ollama ANTHROPIC_BASE_URL=http://localhost:11434 ANTHROPIC_API_KEY="" claude --model qwen3-coder 
```

**Note:** Claude Code requires a large context window. We recommend at least 64k tokens. See the [context length documentation](/context-length) for how to adjust context length in Ollama.

## Recommended Models

- `qwen3-coder` 
- `glm-4.7`
- `gpt-oss:20b`
- `gpt-oss:120b`

Cloud models are also available at [ollama.com/search?c=cloud](https://ollama.com/search?c=cloud).
