Recent updates

• 🔥 News: `2024/8/30`: The CogVLM2 paper has been published on arXiv.
• 🔥 News: `2024/7/12`: We have released CogVLM2-Video online web demo, welcome to experience it.
• 🔥 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.

• 🔥 News: `2024/6/8`:We release CogVLM2 TGI Weight,

which is a model can be inferred in TGI. See Inference Code in here

• 🔥 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.

• 🔥 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.

• 🔥 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:

Benchmark

Image Understand

Our open source models have achieved good results in many lists compared to the previous generation of CogVLM open source models. Its excellent performance can compete with some non-open source models, as shown in the table below:

| Model | Open Source | LLM Size | TextVQA | DocVQA | ChartQA | OCRbench | VCR_EASY | VCR_HARD | MMMU | MMVet | MMBench |…
