Research links longer prompts and solutions to LLM math reasoning failures

A new research paper titled "Too long; didn't solve" investigates the impact of prompt and solution length on the performance of large language models in mathematical reasoning tasks. The study, which utilizes a newly constructed adversarial dataset of expert-authored mathematics problems, found that both increased prompt length and increased solution length correlate with higher model failure rates. While a difficulty-adjusted analysis showed weak negative associations between these length variables and model separation, the primary finding emphasizes that structural length is a significant factor in the empirical difficulty of these mathematical benchmarks.

    Too long; didn't solve

    arXiv:2604.07593v2 Announce Type: replace Abstract: Mathematical benchmarks consisting of a range of mathematics problems are widely used to evaluate the reasoning abilities of large language models, yet little is known about how their structural properties influence model behavi…
