V-Star

V-Star is a benchmark for understanding images combined with text. The official description says: "V* - visual agent benchmark evaluating visual search and grounding capabilities". Below we describe in simple words what benchmarks of this type generally examine.

V-Star measures understanding images combined with text. In detail, it checks:

• answering questions about images (figures, photos, charts, memes)
• reading text inside images and connecting it to the question
• visual reasoning such as counting, locating and comparing objects
• combining what is seen with general knowledge

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Official methodology note: V* - visual agent benchmark evaluating visual search and grounding capabilities.
