Code execution boosts algorithmic reasoning in LLMs over natural language

A new research paper from arXiv explores the effectiveness of code versus natural language for algorithmic reasoning in tool-augmented language models. The study found that using executable code as an intermediate representation significantly outperforms natural-language reasoning by over 31 percentage points on a benchmark of 40 verifiable algorithmic tasks. The researchers introduced an intervention where models generate code and then simulate its execution, demonstrating that the performance gains are primarily due to reliable external execution rather than just a change in the intermediate representation.

    Is Code Better Than Language for Algorithmic Reasoning

    arXiv:2606.15589v1 Announce Type: cross Abstract: For tool-augmented language models, comparing natural-language reasoning with code-execution pipelines is difficult because the comparison changes both the intermediate representation and the execution mechanism. We separate these…
