Provider<TChatOptions extends ChatModelOptions, TEmbeddingsOptions extends EmbeddingsModelOptions, TMediaOptions extends MediaGenerationModelOptions> class abstract

Provides a unified interface for accessing all major LLM, chat, and embedding providers in dartantic_ai.

The interface ensures all providers are accessible without importing provider-specific packages. All configuration (API keys, base URLs, models) is handled via the provider interface.

This interface is used to create a provider instance, which can be used to create a chat model or an embeddings model.

The provider interface is used to create a provider instance, which can be used to create a chat model or an embeddings model.
