VLMEvalKit: An Open-Source ToolKit for Evaluating Large Multi-Modality Models

摘要

We present VLMEvalKit: an open-source toolkit for evaluating large multi-modality models based on PyTorch. The toolkit aims to provide a user-friendly and comprehensive framework for researchers and developers to evaluate existing multi-modality models and publish reproducible evaluation results. In VLMEvalKit, we implement over 70 different large multi-modality models, including both proprietary APIs and open-source models, as well as more than 20 different multi-modal benchmarks. By implementing a single interface, new models can be easily added to the toolkit, while the toolkit automatically handles the remaining workloads, including data preparation, distributed inference, prediction post-processing, and metric calculation. Although the toolkit is currently mainly used for evaluating large vision-language models, its design is compatible with future updates that incorporate additional modalities, such as audio and video. Based on the evaluation results obtained with the toolkit, we host a comprehensive leaderboard (https://huggingface.co/spaces/opencompass/open_vlm_leaderboard) to track the progress of multi-modality learning research. The toolkit is released on GitHub (https://github.com/open-compass/VLMEvalKit) and is actively maintained.
