UniBench - Meta's Vision-Language Model (VLM) Evaluation Framework

What is UniBench

UniBench is a vision-language model (VLM) evaluation framework launched by Meta FAIR, providing comprehensive evaluation of vision-language models (VLMs). UniBench includes over 50 benchmarks, covering multi-dimensional capabilities such as object recognition, spatial understanding, and reasoning. Meta FAIR also launched a "self-taught evaluator" that is trained using synthetic data, reducing reliance on manual annotation, and its performance surpasses commonly used model reviewers such as GPT-4.

Main Features of UniBench
