    Use Cases & Benefits

    • Provides an open-source Python toolkit for evaluating large vision-language models across 80+ benchmarks and 220+ models with one-command execution.
    • Simplifies multi-modal model evaluation by automating data preparation, inference, and metric calculation, enabling reproducible and generation-based assessments.
    • Use for benchmarking new vision-language models on diverse image and video datasets to compare performance with state-of-the-art models.
    • Use for integrating multi-node distributed inference to accelerate evaluation workflows of large or complex multi-modal models.
    • Use for developing and contributing custom benchmarks or model evaluation pipelines within a unified, extensible framework.

    From the README

    A Toolkit for Evaluating Large Vision-Language Models.

    VLMEvalKit (the python package name is vlmeval) is an open-source evaluation toolkit of large vision-language models (LVLMs). It enables one-command evaluation of LVLMs on various benchmarks, without the heavy workload of data preparation under multiple repositories. In VLMEvalKit, we adopt generation-based evaluation for all LVLMs, and provide the evaluation results obtained with both exact matching and LLM-based answer extraction.
