The full dataset comprises 2.11 million English and 346,000 Chinese image-caption entities, each released in both "easy" and "hard" difficulty variants that control how much of the caption text remains visible. **VCR_en_easy** specifically refers to the English-language, easy-difficulty configuration, where a larger fraction of each masked word's pixels remains visible, making the restoration task comparatively more tractable than the hard variant. Crucially, because the caption text is split across small, disconnected pixel fragments rather than presented as clean OCR-able text, a model cannot solve VCR by extracting text and then reasoning purely in the language domain — it must fuse the sparse visual pixel hints with the surrounding image content and any available textual context to reconstruct the full caption correctly. The paper's central finding is that current vision-language models significantly lag behind human performance on this task, and that directly fine-tuning models on VCR-Wiki does not meaningfully close the gap, pointing to a deeper limitation in how current VLMs integrate text-in-image and free-form visual understanding. ## Benchmark Specifications | Field | Value | |---|---| | Task category | Reasoning / pixel-level vision-language text restoration | | Metric | Exact match / accuracy on the restored caption text | | Number of tasks | 2.11M English entities (VCR-Wiki total); VCR_en_easy is the English, easy-difficulty split | | Saturation | Low — current VLMs significantly lag human performance, even after fine-tuning | | Created by | Tianyu Zhang, Suyuchen Wang, Lu Li, Ge Zhang, Perouz Taslakian, Sai Rajeswar, Jie Fu, Bang Liu, Yoshua Bengio (Mila – Quebec AI Institute) | | Source paper | [Zhang et al. 2025](https://arxiv.org/abs/2406.06462) (ICLR 2025) | | GitHub | [tianyu-z/VCR](https://github.com/tianyu-z/VCR) | ## How VCR_en_easy Is Scored A model is shown the partially-masked image and asked to output the full, exact original caption text; scoring is based on exact-match or near-exact string accuracy between the model's restored caption and the ground-truth original caption, typically also reported with a more lenient edit-distance-based partial-credit metric to distinguish near-misses from wholesale failures. ## State-of-the-Art Results > Current vision-language models significantly lag behind human performance on VCR-Wiki tasks, including the easy-difficulty splits.

What is VCR_en_easy?

VCR_en_easy is the English, easy-difficulty split of the VCR-Wiki benchmark, testing whether vision-language models can restore partially occluded text in images using pixel-level and contextual cues.

What does a good VCR_en_easy score look like?

Current vision-language models significantly lag behind human performance even on the easier difficulty split, so accuracy approaching human-level restoration represents strong, currently rare performance.

Who created VCR-Wiki?

VCR-Wiki was created by Tianyu Zhang, Suyuchen Wang, and collaborators including Yoshua Bengio at Mila – Quebec AI Institute, accepted at ICLR 2025.
