Internvl2 5 1B MPO
Overview :
InternVL2_5-1B-MPO is a multimodal large language model (MLLM) built on InternVL2.5 and Mixed Preference Optimization (MPO), showcasing superior overall performance. This model integrates incrementally pre-trained InternViT with various pre-trained large language models (LLMs), including InternLM 2.5 and Qwen 2.5, utilizing a randomly initialized MLP projector. InternVL2.5-MPO retains the ‘ViT-MLP-LLM’ paradigm from InternVL 2.5 and its predecessors while introducing support for multiple images and video data. The model excels in multimodal tasks, capable of handling a variety of visual-language tasks including image captioning and visual question answering.
Target Users :
The target audience includes researchers, developers, and enterprises, particularly those that need to process and comprehend vast amounts of visual and language data. The advanced multimodal capabilities of InternVL2_5-1B-MPO make it an ideal choice in the fields of image recognition, natural language processing, and machine learning.
Use Cases
Generate detailed descriptions for a set of images using InternVL2_5-1B-MPO.
Extract key information from video frames to create a summary of the video content.
Answer specific questions based on image content in visual question answering tasks.
Features
Supports input and processing of multiple images and video data.
Utilizes 'ViT-MLP-LLM' architecture to effectively integrate visual and language information.
Integrates incrementally pre-trained InternViT with multiple pre-trained LLMs to enhance model performance.
Employs dynamic resolution strategies to handle image patches of 448×448 pixels.
Incorporates pixel recomposition operations to reduce the number of visual tokens for increased efficiency.
Uses Mixed Preference Optimization (MPO) that combines preference loss, quality loss, and generation loss to optimize model responses.
How to Use
1. Install the necessary libraries, such as torch and transformers.
2. Load the model from Hugging Face: `model = AutoModel.from_pretrained('OpenGVLab/InternVL2_5-1B-MPO')`.
3. Prepare the input data; if it is an image, ensure proper preprocessing, such as resizing and normalization.
4. Use the tokenizer to convert the text into a format that the model can understand.
5. Input the processed images and text into the model for inference.
6. Perform post-processing based on the model output to obtain the final results.
7. For multiple images or video data, consolidate multiple image patches or frames and provide additional contextual information during input.
