Fico: Evaluating Vision-Language Models under Visual Fidelity and Compression at Scale (2026.findings-acl)
Copied to clipboard
| Challenge: | Visual text compression is emerging paradigm for rendering text as images for processing by vision-language models. |
| Approach: | They propose a benchmark to assess VLM robustness under dense visual inputs. |
| Outcome: | Evaluating 13 general-purpose VLMs and 3 OCR-specialized models reveals performance drops sharply under increased density or reduced resolution; cross-task transfer between OCR, NIAH, and VQA is limited; and VQ is comparatively robust because low-level details are lost before high-level semantics. |
