Multimodal LLMs struggle to read calendar screenshots, new benchmark reveals

A new benchmark, VCCB (Visual Calendar Comprehension Benchmark), has been developed to test how well multimodal large language models can interpret calendar screenshots. Initial results show a significant gap between human performance (around 99%) and even top-tier hosted models (80-85%), with local models and smaller LLMs like Claude Haiku performing much lower (38-58%). The creator is seeking community contributions to run the benchmark with various local models and quantization levels to better understand the impact of quantization on this specific task. AI

IMPACT Highlights a specific capability gap in current multimodal LLMs, potentially guiding future development for agents and visual understanding tasks.
