CogVLM2-Video
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:
-
Significant improvements in many benchmarks such as
TextVQA,DocVQA. - Support 8K content length.
- Support image resolution up to 1344 * 1344 .
- Provide an open source model version that supports both Chinese and English .
Video Understand
CogVLM2-Video achieves state-of-the-art performance on multiple video question answering tasks. The following diagram shows the performance of CogVLM2-Video on the MVBench , VideoChatGPT-Bench and Zero-shot VideoQA datasets (MSVD-QA, MSRVTT-QA, ActivityNet-QA). Where VCG- refers to the VideoChatGPTBench, ZS- refers to Zero-Shot VideoQA datasets and MV-* refers to main categories in the MVBench.
