+# CogVLM2-Video
+[中文版本README](README_zh.md)
+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](https://github.com/OpenGVLab/Ask-Anything), [VideoChatGPT-Bench](https://github.com/mbzuai-oryx/Video-ChatGPT)
+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.

+## Evaluation details
+We follow the previous works to evaluate the performance of our model. In different benchmarks, we craft task-specific
+prompts for each benchmark:
+``` python
+# For MVBench
+prompt = f"Carefully watch the video and pay attention to the cause and sequence of events, the detail and movement of objects, and the action and pose of persons. Based on your observations, select the best option that accurately addresses the question.\n " + f"{prompt.replace('Short Answer.', '')}\n" + "Short Answer:"
+# For VideoChatGPT-Bench
+prompt = f"Carefully watch the video and pay attention to the cause and sequence of events, the detail and movement of objects, and the action and pose of persons. Based on your observations, comprehensively answer the following question. Your answer should be long and cover all the related aspects\n " + f"{prompt.replace('Short Answer.', '')}\n" + "Answer:"
+# For Zero-shot VideoQA
+prompt = f"The input consists of a sequence of key frames from a video. Answer the question comprehensively including all the possible verbs and nouns that can discribe the events, followed by significant events, characters, or objects that appear throughout the frames.\n " + f"{prompt.replace('Short Answer.', '')}\n" + "Answer:"
+```
+For evaluation codes, please refer to
+the [evaluation script](https://github.com/magic-research/PLLaVA/blob/main/README.md) in PLLaVA.
+## Using This Model
+This repository is a `chat` version model and it support single-round chat.
+You can quickly install the Python package dependencies and run model inference in
+our [github](https://github.com/THUDM/CogVLM2/tree/main/video_demo).
