Talking to Itself While Coding: What Makes Comments Help Code Generation?
TL;DR
Large Language Models (LLMs) benefit from natural-language comments during code generation, but not all comments are equally effective. Comments that convey correct solution content significantly improve code generation performance, while irrelevant comments can hinder it.
✦ Why It Matters
Focus on crafting relevant comments to improve code generation outcomes in your projects.
Key Takeaways
- Use comments that convey correct solution content for better code generation.
- Avoid irrelevant comments that can reduce performance.
- Leverage strong models to generate effective comments for weaker models.
- Test the impact of comments on code generation in your workflows.
How It Works
The study utilized observational analyses and controlled interventions to assess the impact of comments on code generation. By pre-filling weaker models with comments from stronger models, researchers could isolate the effect of comment content from their surface form.
This approach revealed that comments with relevant solution content significantly enhance the performance of code generation models.
