A new study published on arXiv investigates the effectiveness of code comments in improving the performance of large language models (LLMs) during code generation. Researchers found that comments from successful code solutions significantly boost recipient models' performance, increasing their pass@1 rate by an average of 17.2%. Conversely, comments describing failed solutions or those written for different problems do not provide reliable gains and can even decrease performance. The study suggests that the benefit of comments stems from their ability to convey correct solution content, rather than just their presence. AI
IMPACT Code generation models may improve significantly by incorporating comments that provide correct solution content.
