### Model Configuration

* **Main Model** (`ANTHROPIC_MODEL`): Primary code generation and complex tasks
* **Haiku Model** (`ANTHROPIC_DEFAULT_HAIKU_MODEL`): Background tasks, quick responses

### Single Model Configuration

Set both variables to the same model, or use `/model haiku` command after startup.
