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. |

| Challenge: | lack of reliable reward models for tool-use tasks has limited progress toward agentic AI . recent advances in agentic artificial intelligence are driven by tool-using capabilities of large language models. |
| Approach: | They propose a pipeline that constructs pairwise preference data using rule-based scoring and multidimensional sampling to build lightweight reward models. |
| Outcome: | The proposed model outperforms existing models on tool calling tasks with higher accuracy. |

| Challenge: | Existing benchmarks for long-form generation assess real-world queries with hard-to-verify metrics or use synthetic setups that overlook real-life intricacies. |
| Approach: | They propose a new approach that balances verifiable and real-world assessment with Target-Anchored Evaluation. |
| Outcome: | The proposed model balances real-world and verifiable assessment with Target-Anchored Evaluation (TAE) it generates queries, textual materials, and anchors based on verifier targets within real-life scenarios . |

Yinger Zhang, Shutong Jiang, Renhao Li, Jianhong Tu, Yang Su, Lianghao Deng, Xudong Guo, ChenXu Lv, Junyang Lin
| Challenge: | Existing LLM planning benchmarks emphasize local, step-level reasoning rather than global constrained optimization. |
| Approach: | They propose a benchmark for practical long-horizon agent planning that uses local constrained reasoning and global constrained optimization. |
| Outcome: | The proposed benchmarks show that even frontier agentic LLMs struggle with these problems. |
