Making AI coding assistants better, even for your weird DSLs - George Fahmy



AI Summary

Summary of the Video

  1. Presenter Background
    • George, founder of Stackpack.
    • Focus on improving developer experience in coding assistants for domain-specific languages (DSLs).
  2. Challenges with LLMs and DSLs
    • LLMs excel in writing actual code but struggle with DSLs like SQL, Terraform, and Kubernetes due to their complexity and variability.
    • Performance drops significantly with unfamiliar or less popular DSLs due to limited training data.
    • Rapid updates in DSLs (e.g., Kubernetes) further complicate LLM performance.
  3. Techniques to Improve LLM Performance with DSLs
    • Bounded Decoding: Ensures valid code generation by using finite automata based on regex, leading to 100% valid outputs.
    • Retriever-Augmented Generation (RAG): Enhances performance by using contextual information from user projects and documentation, with a focus on query expansion and proper sourcing from documentation rather than just code samples.
    • Grammar Prompting: Teaches LLM the rules of DSLs using BNF format, improving accuracy, especially for new DSLs.
    • Recovery and Retry: Incorporates static analysis to validate generated code and provide feedback for corrections.
  4. Implementation Insights
    • Combining these techniques can lead to significant performance enhancements with minimal resources, showing that smaller models can still be effective with the right structures in place.
    • Importance of continuous feedback and adaptation for LLMs to handle the dynamic nature of DSLs.
