New benchmark reveals bias and reasoning gaps in advanced AI math proof evaluation

By PulseAugur Editorial · [1 sources] ·

A new benchmark called QEDBench has been introduced to evaluate the alignment gap in automated assessment of university-level mathematical proofs. The benchmark reveals that several advanced LLMs, including Claude Opus 4.5, DeepSeek-V3, Qwen 2.5 Max, and Llama 4 Maverick, exhibit a positive bias in their scoring. Additionally, the research highlights a significant performance degradation in discrete mathematical domains for models like GPT-5 Pro and Claude Sonnet 4.5, despite Gemini 3.0 Pro achieving state-of-the-art results.

    QEDBENCH: Quantifying the Alignment Gap in Automated Evaluation of University-Level Mathematical Proofs

    arXiv:2602.20629v3 Announce Type: replace Abstract: As Large Language Models (LLMs) saturate elementary benchmarks, the research frontier has shifted from generation to the reliability of automated evaluation. We demonstrate that standard "LLM-as-a-Judge" protocols suffer from a …
