This repository contains KC-MMBench, a new benchmark dataset meticulously tailored for real-world short-video scenarios, as presented in the paper "Kwai Keye-VL Technical Report". Constructed from Kuaishou short video data, KC-MMBench comprises 6 distinct datasets designed to evaluate the performance of Vision-Language Models (VLMs) like Kwai Keye-VL-8B, Qwen2.5-VL, and InternVL in comprehending dynamic, information-dense short-form videos.

For the associated code, detailed documentation, and evaluation scripts, please refer to the official Kwai Keye-VL GitHub repository.

If you want to use KC-MMbench, please download with:

git clone https://huggingface.co/datasets/Kwai-Keye/KC-MMbench

Usage

This section provides a quick guide on how to interact with models using the keye-vl-utils library, which is essential for processing and integrating visual language information with Keye Series Models like Kwai Keye-VL-8B.

Install keye-vl-utils

First, install the necessary utility library:

pip install keye-vl-utils

Keye-VL Inference Example

Here's an example of performing inference with a Kwai Keye-VL model, demonstrating how to prepare inputs for both image and video scenarios.

from transformers import AutoModel, AutoProcessor
from keye_vl_utils import process_vision_info

# default: Load the model on the available device(s)
model_path = "Kwai-Keye/Keye-VL-8B-Preview"

model = AutoModel.from_pretrained(
    model_path, torch_dtype="auto", device_map="auto", attn_implementation="flash_attention_2", trust_remote_code=True,
).to('cuda')

# Example messages demonstrating various input types (image, video)
messages = [
    # Image Input Examples
    [{"role": "user", "content": [{"type": "image", "image": "file:///path/to/your/image.jpg"}, {"type": "text", "text": "Describe this image."}]}],
    [{"role": "user", "content": [{"type": "image", "image": "http://path/to/your/image.jpg"}, {"type": "text", "text": "Describe this image."}]}],
    [{"role": "user", "content": [{"type": "image", "image": "data:image;base64,/9j/..."}, {"type": "text", "text": "Describe this image."}]}],
    
    # Video Input Examples (most relevant for KC-MMBench)
    [{"role": "user", "content": [{"type": "video", "video": "file:///path/to/video1.mp4"}, {"type": "text", "text": "Describe this video."}]}],
    [{"role": "user", "content": [{"type": "video", "video": ["file:///path/to/extracted_frame1.jpg", "file:///path/to/extracted_frame2.jpg", "file:///path/to/extracted_frame3.jpg"],}, {"type": "text", "text": "Describe this video."},],}],
    [{"role": "user", "content": [{"type": "video", "video": "file:///path/to/video1.mp4", "fps": 2.0, "resized_height": 280, "resized_width": 280}, {"type": "text", "text": "Describe this video."}]}],
]

processor = AutoProcessor.from_pretrained(model_path)
# Note: model loaded above already
text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
images, videos, video_kwargs = process_vision_info(messages, return_video_kwargs=True)
inputs = processor(text=text, images=images, videos=videos, padding=True, return_tensors="pt", **video_kwargs).to("cuda")
generated_ids = model.generate(**inputs)
print(generated_ids)
