Where it stands
Still moving The best reported result is still improving on 3 of 6 tracked benchmarks.
49 papers in 2023–24 and 48 in 2025–26 (at ICML, NeurIPS, ICLR, CVPR and AAAI); its share of the topic shrank, from 13.2% to 9.6%.
Open questions the data points to
- ImageNet-V2 (accuracy): best went from 65.13 (up to 2024) to 72.38 in 2025 — LoR-VP: Low-Rank Visual Prompting for Efficient Vision Model Adaptation (ICLR 2025 · 0 citations)
- ImageNet-A (accuracy): best went from 51.47 (up to 2024) to 60.72 in 2025 — DynaPrompt: Dynamic Test-Time Prompt Tuning (ICLR 2025 · 0 citations)
- ImageNet-R (accuracy): best went from 77.89 (up to 2024) to 79.57 in 2025 — DynaPrompt: Dynamic Test-Time Prompt Tuning (ICLR 2025 · 0 citations)
- Papers report CoOp on ImageNetV2 (accuracy) anywhere from 54.26 to 64.2: comparisons against it depend on whose number you take.
- Papers report CoOp on ImageNet-Sketch (accuracy) anywhere from 32.47 to 47.99: comparisons against it depend on whose number you take.
What looks settled
- ImageNet-Sketch (accuracy): best up to 2024 49.55, best in 2025–26 48.22 from 2 papers, at most 0.2% better, if at all.
- Domain generalization, ImageNet-A (accuracy): best up to 2024 51.64, best in 2025–26 51.97 from 2 papers, less than 1% better.
- Domain generalization, ImageNet-R (accuracy): best up to 2024 77.56, best in 2025–26 78.01 from 2 papers, less than 1% better.
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.
