Built for model choice
Keep your application interface consistent while your team evaluates and uses supported models from multiple providers.
One integration
Use a consistent API layer instead of maintaining separate application integrations for every supported model provider.

Change the selected model at the API layer when your use case, cost target, latency needs, or provider availability changes.
Developer-first
Designed around familiar API concepts, clear documentation, and straightforward model identifiers.
