A provider is a company or service that supplies something another app uses. In AI, a provider may offer access to models that can answer questions, summarize text, or help with code.
Think of it like choosing a phone company to connect your device to a network. Your app makes a request to the provider, and the provider sends back a response.
Different providers can offer different tools, rules, and costs. Before connecting one, check what information your app sends and how the provider handles it.
