## News 🚀🚀🚀

- `2024/12/20`: 🔥 We release the [InternVL2.5-MPO](https://internvl.github.io/blog/2024-12-20-InternVL-2.5-MPO/), which is finetuned with [Mixed Preference Optimization](https://huggingface.co/papers/2411.10442) on [MMPR-v1.1](https://huggingface.co/datasets/OpenGVLab/MMPR-v1.1). **The resulting models outperform their counterparts without MPO by an average of 2 points across all model scales on the OpenCompass leaderboard.** These models are available at [HF link](https://huggingface.co/collections/OpenGVLab/internvl25-mpo-6753fed98cd828219b12f849).
- `2024/12/17`: 🚀 [InternVL2/2.5](https://github.com/PaddlePaddle/PaddleMIX/tree/develop/paddlemix/examples/internvl2) is supported in [PaddleMIX](https://github.com/PaddlePaddle/PaddleMIX) by Paddle Team.
- `2024/12/05`: 🚀 We release the [InternVL2.5](https://huggingface.co/collections/OpenGVLab/internvl-25-673e1019b66e2218f68d7c1c), an advanced multimodal large language model (MLLM) series with parameter coverage ranging from 1B to 78B. [InternVL2_5-78B](https://huggingface.co/OpenGVLab/InternVL2_5-78B) is the first open-source MLLMs to achieve over **70%** on the **MMMU benchmark**, matching the performance of leading closed-source commercial models like GPT-4o. These models are available at [HF link](https://huggingface.co/collections/OpenGVLab/internvl-25-673e1019b66e2218f68d7c1c).
- `2024/11/14`: We introduce [MMPR](https://huggingface.co/datasets/OpenGVLab/MMPR), a high-quality, large-scale multimodal reasoning preference dataset, and [MPO](https://github.com/OpenGVLab/InternVL/tree/main/internvl_chat/shell/internvl2.0_mpo), an effective preference optimization algorithm. The resulting model, [InternVL2-8B-MPO](https://huggingface.co/OpenGVLab/InternVL2-8B-MPO), achieves an accuracy of 67.0 on MathVista. Please refer to our [paper](https://arxiv.org/abs/2411.10442), [project page](https://internvl.github.io/blog/2024-11-14-InternVL-2.0-MPO/) and [document](https://internvl.readthedocs.io/en/latest/internvl2.0/preference_optimization.html) for more details.
- `2024/10/21`: We release the Mini-InternVL series. These models achieve impressive performance with minimal size: the 4B model achieves 90% of the performance with just 5% of the model size. For more details, please check our [project page](https://github.com/OpenGVLab/InternVL/tree/main/internvl_chat/shell/mini_internvl) and [document](https://internvl.readthedocs.io/en/latest/internvl2.0/domain_adaptation.html).
- `2024/08/01`: The [Chartmimic](https://chartmimic.github.io/) team evaluated the InternVL2 series models on their benchmark. The InternVL2-26B and 76B models achieved the top two performances among open-source models, with the InternVL2 76B model surpassing GeminiProVision and exhibiting comparable results to Claude-3-opus.
- `2024/08/01`: InternVL2-Pro achieved the SOTA performance among open-source models on the [CharXiv](https://charxiv.github.io/#leaderboard) dataset, surpassing many closed-source models such as GPT-4V, Gemini 1.5 Flash, and Claude 3 Sonnet.
- `2024/07/24`: The [MLVU](https://github.com/JUNJIE99/MLVU) team evaluated InternVL-1.5 on their benchmark. The average performance on the multiple-choice task was 50.4%, while the performance on the generative tasks was 4.02. The performance on the multiple-choice task ranked #1 among all open-source MLLMs.
- `2024/07/04`: We release the [InternVL2 series](https://huggingface.co/collections/OpenGVLab/internvl-20-667d3961ab5eb12c7ed1463e). InternVL2-Pro achieved a 62.0% accuracy on the MMMU benchmark, matching the performance of leading closed-source commercial models like GPT-4o.
