OCR-Reasoning Benchmark: Unveiling the True Capabilities of MLLMs in Complex Text-Rich Image Reasoning

arXiv:2505.17163v2 Announce Type: replace Abstract: Recent advancements in multimodal slow-thinking systems have demonstrated remarkable performance across various visual reasoning tasks. However, their capabilities in text-rich image reasoning tasks remain understudied due to the absence of a dedicated and systematic benchmark. To address this gap, we propose OCR-Reasoning, a novel benchmark designed to systematically assess Multimodal Large Language Models on text-rich image reasoning tasks. Specifically, OCR-Reasoning comprises 1,069 human-annotated examples spanning 6 core reasoning abilit

Why this matters
Why now

The proliferation of Multimodal Large Language Models (MLLMs) and increasing demand for sophisticated AI applications necessitates robust evaluation benchmarks to understand their true capabilities and limitations in complex real-world tasks.

Why it’s important

This benchmark addresses a crucial gap in evaluating MLLMs, moving beyond simple visual reasoning to complex text-rich image understanding, which is vital for developing reliable and capable AI systems in fields like document processing, autonomous vehicles, and accessibility.

What changes

The introduction of OCR-Reasoning provides a standardized method to systematically assess MLLMs' performance on tasks requiring both optical character recognition and advanced reasoning, pushing the boundaries of current model development and revealing areas for improvement.
