To start running evaluations on RagaAI Catalyst, you need specify the API keys to your LLM models. Follow these steps to set your API keys:

1. Navigate to Settings -> API Keys.
2. Enter your API key against the relevant supported model names by clicking "Edit"
3. Click "Save" to store the API Key(s).

### Via SDK:

Alternatively, you can also define your API keys on the SDK using the following commands:

```python
from ragaai_catalyst import RagaAICatalyst

catalyst = RagaAICatalyst(
    api_keys={"OPENAI_API_KEY": OPENAI_API_KEY} #similarly for other supported keys
)
```
