# Adding a New API Provider
|
|
|
|
This guide will walk you through the process of adding a new API provider to Llama Stack.
|
|
|
|
|
|
- Begin by reviewing the [core concepts](../concepts/index.md) of Llama Stack and choose the API your provider belongs to (Inference, Safety, VectorIO, etc.)
|
|
- Determine the provider type ({repopath}`Remote::llama_stack/providers/remote` or {repopath}`Inline::llama_stack/providers/inline`). Remote providers make requests to external services, while inline providers execute implementation locally.
|
|
- Add your provider to the appropriate {repopath}`Registry::llama_stack/providers/registry/`. Specify pip dependencies necessary.
|
|
- Update any distribution {repopath}`Templates::llama_stack/templates/` build.yaml and run.yaml files if they should include your provider by default. Run {repopath}`llama_stack/scripts/distro_codegen.py` if necessary. Note that `distro_codegen.py` will fail if the new provider causes any distribution template to attempt to import provider-specific dependencies. This usually means the distribution's `get_distribution_template()` code path should only import any necessary Config or model alias definitions from each provider and not the provider's actual implementation.

## Testing the Provider
|
|
|
|
### 1. Integration Testing
|
|
- Create integration tests that use real provider instances and configurations
|
|
- For remote services, test actual API interactions
|
|
- Avoid mocking at the provider level since adapter layers tend to be thin
|
|
- Reference examples in {repopath}`tests/api`
|
|
|
|
### 2. Unit Testing (Optional)
|
|
- Add unit tests for provider-specific functionality
|
|
- See examples in {repopath}`llama_stack/providers/tests/inference/test_text_inference.py`
|
|
|
|
### 3. End-to-End Testing
|
|
1. Start a Llama Stack server with your new provider
|
|
2. Test using client requests
|
|
3. Verify compatibility with existing client scripts in the [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main) repository
|
|
4. Document which scripts are compatible with your provider
