Details

The mlx-vlm chat application is structured around a central MLXVisionChat component that manages the entire chat session. This component integrates with a Chat UI for user interaction, providing a continuous Chat Loop that processes user input. Within this loop, a Command Handler dispatches specific commands, including those for an Image Processor to handle visual inputs and a Help Displayer for user guidance. Textual and multimodal responses are generated by a Response Generator which interfaces with the VLM, and all interactions are recorded by a History Manager to maintain conversation context. This design ensures a clear separation of concerns, with the MLXVisionChat class acting as the primary coordinator for the application's core functionalities.

MLXVisionChat

Serves as the central orchestrator, encapsulating the entire chat application's state and high-level logic. It manages the VLM instance and overall chat session, acting as the main controller for the UI.
