Long context

Switchyard is NVIDIA's open-source model router. Instead of answering every request with one model, it sends each one to either a low-cost or a high-capability model, using one of its routing algorithms to decide which the request really needs. By default it picks a popular cheap model and a popular strong one; you can name your own two choices in the models parameter.

It accepts text input and returns text, and supports streaming. Switchyard is commonly used for lowering the cost of mixed workloads, sending simple requests to cheap models, and keeping strong models for the hard ones. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Each request is billed at the price of the model the router chooses for it, shown per request in your usage log. There is no fixed monthly fee. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
