Researchers have developed AstroVLBench, a new benchmark designed to systematically evaluate vision-language models (VLMs) on observational astronomy tasks. The benchmark includes over 4,100 instances across five different astronomical data modalities. Evaluations of six leading models revealed significant performance variations depending on the data type, with Gemini 3 Pro showing the most consistent capability, though all models underperformed specialized methods.
