What do Provider and Model mean in this configuration, and where will my request actually go?

A Provider is the service platform through which you access an AI model.A model vendor, cloud platform, aggregation gateway, or even a local model service may appear as a Provider in a tool. It receives requests and provides model access, often handling credentials, rate limits, or billing, but it does not necessarily train or directly run the underlying model. Check the Base URL, key issuer, and billing party to identify the actual path.
