Core Features

Inference and Fine-Tuning

MLX-VLM provides tools for inference and fine-tuning of Vision Language Models, allowing users to apply these models to various tasks.

Source: README
Speculative Decoding

This feature speeds up generation by drafting several candidate tokens with a small 'drafter' model and verifying them in a single target forward pass, supporting drafter families like DFlash and Gemma 4 MTP.

Source: README
Multi-Modal Generation

MLX-VLM supports generating outputs that combine different modalities, such as images, text, and audio, enhancing the versatility of the models.

Source: README
Chat UI with Gradio

The package includes a chat interface using Gradio, making it easier for users to interact with the models.

Source: README
Python Script Support

MLX-VLM can be integrated into Python scripts, providing flexibility for developers to use the package in various applications.
