```

### LiteLLM YAML Config

```yaml
model_list:
  - model_name: llama-3.2-3b
    litellm_params:
      model: bytez/meta-llama/Llama-3.2-3B-Instruct
      api_key: "env:BYTEZ_KEY"
```

## Usage Examples

## Notes

Bytez provides serverless access to open-weight models published on Hugging Face. Use the Hugging Face model ID (e.g., `meta-llama/Llama-3.2-3B-Instruct`) as the model name in requests. Models cold-start on first request; subsequent requests to the same model are faster. Get an API key at bytez.com. Tool use and embeddings are not supported.
