How providers work
When you make a request, Lumenfall:- Matches your requested model to providers that support it
- Selects the best provider based on routing rules
- Sends your request to the provider
- Returns the response (or fails over to another provider if needed)
Forcing a specific provider
By default, Lumenfall automatically selects the best provider. You can bypass routing and force a specific provider by prefixing the model name with the provider slug from the table above.OpenAI-compatible providers
Lumenfall also supports custom OpenAI-compatible endpoints. This allows integration with self-hosted models or other providers that implement the OpenAI API specification.Custom provider configuration is currently available by request. Contact support if you need to connect a custom endpoint.
