Summary
This research article examines the limitations of large reasoning models (LRMs) - fine-tuned LLMs designed for step-by-step reasoning. While LRMs perform well on existing benchmarks like NLGraph, the study reveals they fail catastrophically when reasoning problems exceed modest complexity. The researchers developed a new dataset called Deep Reasoning Dataset (DeepRD) to test scalable complexity and found that LRM performance drops abruptly at sufficient complexity levels and doesn't generalize. The analysis shows most real-world reasoning problems fall within LRMs' success range, but the long tails of complex problems expose significant failure potential, highlighting both near-term utility and the need for new methods that can generalize beyond training distribution complexity.
Key quotes
· 4 pulledLRM performance on graph and reasoning benchmarks such as NLGraph seem extraordinary, with some even claiming they are capable of generalized reasoning and innovation in reasoning-intensive fields such as mathematics, physics, medicine, and law.
We find that the performance of LRMs drop abruptly at sufficient complexity and do not generalize.
We find the majority of real-world examples fall inside the LRMs' success regime, yet the long tails expose substantial failure potential.
Our analysis highlights the near-term utility of LRMs while underscoring the need for new methods that generalize beyond the complexity of examples in the training distribution.
