Phi-3-Vision VLM Model for Apple MLX: An All-in-One Port

This project brings the powerful phi-3-vision VLM to Apple's MLX framework, offering a comprehensive solution for various text and image processing tasks. With a focus on simplicity and efficiency, this implementation offers a straightforward and minimalistic integration of the VLM model. It seamlessly incorporates essential functionalities such as generating quantized model weights, optimizing KV cache quantization during inference, facilitating LoRA/QLoRA training, and conducting model benchmarking, all encapsulated within a single file for convenient access and usage.

Key Features

• Su-scaled RoPE: Implements Su-scaled Rotary Position Embeddings to manage sequences of up to 128K tokens.
• Model Quantization: Reduce model size for faster loading and deployment (2.3GB quantized vs 8.5GB original).
• KV Cache Quantization: Optimize inference for processing long contexts with minimal overhead (5.3s quantized vs 5.1s original).
• LoRA Training: Easily customize the model for specific tasks or datasets using LoRA.
• Benchmarking: Quickly assess model performance on any dataset (WIP).

Usage

prompt = "<|user|>\n<|image_1|>\nWhat is shown in this image?<|end|>\n<|assistant|>\n"
images = [Image.open(requests.get("https://assets-c4akfrf5b4d3f4b7.z01.azurefd.net/assets/2024/04/BMDataViz_661fb89f3845e.png" , stream=True).raw)]

Image Captioning

model, processor = load()
generate(model, processor, prompt, images)
