Use in Smart Balancers
A public model can be the destination of a Smart Balancer route or the classifier model that drives intent_classifier routing. In both cases, reference the model by catalog name (with or without the public: prefix — the platform normalises it).
As a route destination
Pick Public modelas the destination type and the catalog name as the reference. The balancer calls the public model directly when the route matches. The destination inherits the route's priority and enabled flag; no scheduler interaction is required since the public model is always available.
As the intent classifier
Set the routing mode to intent_classifier, pick public_modelas the router type, and reference the catalog name. The classifier itself runs as a public model, so no GPU budget is consumed by the routing step. A small model from the catalog (such as a GPT-OSS 20B variant) is usually the right choice — the classifier only reads the prompt and the route intents, it does not generate user-facing content.
