+model name, a set of capabilities, and additional options. Usually, bridges to specific providers extend this base class
+to provide a quick start for vendor-specific models and their capabilities.
 
 Capabilities are a list of strings defined by :class:`Symfony\\AI\\Platform\\Capability`, which can be used to check if a model
 supports a specific feature, like ``Capability::INPUT_AUDIO`` or ``Capability::OUTPUT_IMAGE``.
 
 Options are additional parameters that can be passed to the model, like ``temperature`` or ``max_tokens``, and are
 usually defined by the specific models and their documentation.
 
+Additionally, the component provides two more specific base classes, that are needed to trigger built-in API endpoint
+and result conversion implementations:
+
+* :class:`Symfony\\AI\\Platform\\Model\\CompletionsModel` - for models that support text completions
+* :class:`Symfony\\AI\\Platform\\Model\\EmbeddingsModel` - for models that support vector embeddings

+Platforms like `LiteLLM`_ or `OpenRouter`_ provide a unified API to access multiple models from different providers.
+Therefore, they rely on endpoint and contract design, that is inspired by OpenAI's original GPT API - an implicit
+standard in the industry. Platforms using this de facto standard can be used without the need of a dedicated bridge, by
+using built-in classes::
