LLM algorithm implementation accuracy varies by specification format, study finds

A new study published on arXiv investigates how different formats for specifying algorithms impact the accuracy of machine learning implementations generated by large language models (LLMs). The research compared prose, LaTeX pseudocode, PDF-extracted pseudocode, Markdown, YAML-like, JSON-like, and Python code stubs across five machine learning tasks and three models. Results indicated that LaTeX algorithm-style pseudocode, YAML-like specifications, and ordinary prose showed the largest format effects under core-information settings, while GPT-5.4 mini demonstrated no format differences in matched comparisons under complete information.
