PROVIDERS
PROVIDERS is a single Chat engine over the model aggregators, in Chat — /chat?engine=providers.

What it does
Section titled “What it does”Wraps three aggregators — FreeInference, OpenRouter and TokenRouter — behind one engine, exposing hundreds of models including free tiers. Any single aggregator key turns the engine on. It also joins the fleet as a global-model family: a pick is addressed as providers::<aggregator>::<model>, so an aggregator model can be set as the global model in the top bar.
Key actions
Section titled “Key actions”- Pick an aggregator and model — from the combined catalog of hundreds of models.
- Use free tiers — many models are available at no cost.
- Set as global model — any aggregator model can drive the default-engine apps (Loop, Pipeline).
Set at least one aggregator key in .env.local, then restart the server:
FREEINFERENCE_API_KEY(FreeInference also serves/v1/modelskeyless)OPENROUTER_API_KEYTOKENROUTER_API_KEY(plusTOKENROUTER_URL)
Any one key is enough to enable the engine; add more to widen the catalog.
- FreeInference exposes its model list without a key, so the catalog can be browsed before you commit a key.
