title: Claude Code
|
|
---
|
|
|
|
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 `qwen3-coder`, `gpt-oss:20b`, or other models.

|
## 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
|
|
|
|
Claude Code connects to Ollama using the Anthropic-compatible API.
|
|
|
|
1. Set the environment variables:
|
|
|
|
```shell
|
|
export ANTHROPIC_AUTH_TOKEN=ollama
|
|
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 claude --model gpt-oss:20b
|
|
```
|
|
|
|
**Note:** Claude Code requires a large context window. We recommend at least 32K tokens. See the [context length documentation](/context-length) for how to adjust context length in Ollama.
|
|
|
|
## Connecting to ollama.com
|
|
|
|
1. Create an [API key](https://ollama.com/settings/keys) on ollama.com
|
|
2. Set the environment variables:
|
|
|
|
```shell
|
|
export ANTHROPIC_BASE_URL=https://ollama.com
|
|
export ANTHROPIC_API_KEY=<your-api-key>
|
|
```
|
|
|
|
3. Run Claude Code with a cloud model:
|
|
|
|
```shell
|
|
claude --model glm-4.7:cloud
|
|
```
|
|
|
|
## Recommended Models
|
|
|
|
### Cloud models
|
|
- `glm-4.7:cloud` - High-performance cloud model
|
|
- `minimax-m2.1:cloud` - Fast cloud model
|
|
- `qwen3-coder:480b` - Large coding model
|
|
|
|
### Local models
|
|
- `qwen3-coder` - Excellent for coding tasks
|
|
- `gpt-oss:20b` - Strong general-purpose model
|
|
- `gpt-oss:120b` - Larger general-purpose model for more complex tasks |
