Where it stands
Still moving The best reported result is still improving on 1 of 2 tracked benchmarks.
4 papers in 2023–24 and 113 in 2025–26 (at ICML, NeurIPS, ICLR, CVPR and AAAI); its share of the topic grew, from 1.9% to 5.2%.
Open questions the data points to
- MMBench (score): best went from 64.3 (up to 2024) to 75.7 in 2025 — HiRes-LLaVA: Restoring Fragmentation Input in High-Resolution Large Vision-Language Models (CVPR 2025 · 5 citations)
- GQA (accuracy) is new: first reported in 2025–26 by 4 papers.
How this is decided
A benchmark is tracked when at least four papers of this approach report their own method on the same dataset and metric in at least two different years. Its record is the best number reported up to 2024 compared with the best reported in 2025–26: still improving means at least 1% better, flat means at most 0.2% better with at least two papers from 2025–26 trying. Numbers on a different scale from the rest (a fraction among percentages) and far outliers are left out. Results come from different papers with different setups, so they are signals, not head-to-head comparisons. The share of papers is counted at ICML, NeurIPS, ICLR, CVPR and AAAI.
