Internvl2 5 78B MPO
Overview :
InternVL2.5-MPO is a series of multimodal large language models based on InternVL2.5 and Mixed Preference Optimization (MPO). It excels in multimodal tasks by integrating the recently incrementally pre-trained InternViT with various pre-trained large language models (LLMs) such as InternLM 2.5 and Qwen 2.5, utilizing a randomly initialized MLP projector. This model series has been trained on the multimodal reasoning preference dataset MMPR, which contains approximately 3 million samples, enhancing the model's reasoning capabilities and answer quality through an effective data construction process and mixed preference optimization techniques.
Target Users :
The target audience includes researchers, developers, and enterprises, suitable for scenarios that require multimodal understanding and generation, such as smart assistants, content creation, image and video analysis, etc. The model's high performance and flexibility make it an ideal choice for handling complex multimodal tasks.
Use Cases
As a smart assistant, understand user-uploaded images or videos and engage in conversation
In content creation, generate descriptive text or stories based on images
For image and video analysis, provide detailed analytical reports and insights
Features
Supports multimodal data processing, including images and videos
Employs mixed preference optimization techniques to enhance model performance
