```
npm install -g @anthropic-ai/claude-code
```

- Create an OpenRouter account.
- Generate an API key (
`sk-or-v1-...`

). - Add credits if you're using paid models.

Add the following environment variables to your `~/.zshrc`

or `~/.bashrc`

:

```
export OPENROUTER_API_KEY="sk-or-v1-..."

export ANTHROPIC_BASE_URL="https://openrouter.ai/api"
export ANTHROPIC_AUTH_TOKEN="$OPENROUTER_API_KEY"
export ANTHROPIC_API_KEY=""
```

Restart your terminal after saving the changes.

```
export ANTHROPIC_DEFAULT_HAIKU_MODEL="deepseek/deepseek-v4-flash"
export ANTHROPIC_DEFAULT_SONNET_MODEL="deepseek/deepseek-v4-flash"
export ANTHROPIC_DEFAULT_OPUS_MODEL="deepseek/deepseek-v4-flash"
```

(Optional) Configure Claude Code sub-agents to use the same model:

```
export CLAUDE_CODE_SUBAGENT_MODEL="deepseek/deepseek-v4-flash"
```

If you've previously logged into Claude Code using Anthropic, run:

```
/logout
```

Then restart Claude Code to avoid authentication conflicts.

Start Claude Code:

```
claude
```

Inside Claude Code, run:

```
/status
```

Verify that:

**Anthropic Base URL** is`https://openrouter.ai/api`

**Auth Token** is`ANTHROPIC_AUTH_TOKEN`

Finally, send a prompt and open the **OpenRouter Activity** dashboard to confirm the request is being processed by:

```
deepseek/deepseek-v4-flash
```
