Recent updates

  • πŸ”₯ News: 2024/8/30: The CogVLM2 paper has been published on arXiv.
  • πŸ”₯ News: 2024/7/12: We have released CogVLM2-Video online web demo, welcome to experience it.
  • πŸ”₯ News: 2024/7/8: We released the video understanding version of the CogVLM2 model, the CogVLM2-Video model. By extracting keyframes, it can interpret continuous images. The model can support videos of up to 1 minute. See more in our blog.
  • πŸ”₯ News: 2024/6/8:We release CogVLM2 TGI Weight, which is a model can be inferred in TGI. See Inference Code in here
  • πŸ”₯ News: 2024/6/5:We release GLM-4V-9B, which use the same data and training recipes as CogVLM2 but with GLM-9B as the language backbone. We removed visual experts to reduce the model size to 13B. More details at GLM-4 repo.
  • πŸ”₯ News: 2024/5/24: We have released the Int4 version model, which requires only 16GB of video memory for inference. You can also run on-the-fly int4 version by passing --quant 4.
  • πŸ”₯ News: 2024/5/20: We released the next generation model CogVLM2, which is based on llama3-8b and is equivalent (or better) to GPT-4V in most cases ! Welcome to download!

Model introduction

We launch a new generation of CogVLM2 series of models and open source two models based on Meta-Llama-3-8B-Instruct. Compared with the previous generation of CogVLM open source models, the CogVLM2 series of open source models have the following improvements:

  1. Significant improvements in many benchmarks such as TextVQA, DocVQA.
  2. Support 8K content length.
  3. Support image resolution up to 1344 * 1344.
  4. Provide an open source model version that supports both Chinese and English.

You can see the details of the CogVLM2 family of open source models in the table below:
