AI Reasoning: Harnessing Architecture Over Scale for Numerical Tasks

A new research paper explores the effectiveness of different AI system architectures for quantitative reasoning tasks, particularly in document understanding. The study found that for tasks involving numerical reasoning, the application architecture and retrieval methods were more impactful than the sheer scale of the language model. Specifically, a "Program-of-Thoughts" prompting technique significantly improved a smaller 7B parameter model, while offering minimal gains to a much larger 72B model. The research also highlighted that the quality of input data, such as the legibility of scanned documents, can drastically affect system performance, even causing a previously successful system to collapse.

    When Harness Beats Scale, and When Reading Beats Both

    We describe our system for DocSem, the document-grounded quantitative reasoning shared task at DocInsights 2026, and analyze why it succeeded on labeled data and failed on the test set. The pipeline pairs hybrid block retrieval with Program-of-Thoughts (PoT) generation executed i…
