How I Made AI Worse By Trying To Make It Better



AI Summary

Summary of AI Extraction Tool Development

Introduction

  • Topic: The speaker discusses their experience of trying to build a complex PDF extraction tool and the lessons learned.

Bitter Lessons

  • Macro Bitter Lesson: Investing effort in tweaking AI models often leads to diminishing returns. Focus on improving AI models overall rather than short-term fixes.
  • Micro Bitter Lesson: Overengineering systems can lead to brittleness and inefficiency.

Key Experience

  • Attempted to create an extraction tool for PDFs with approximately 3,000 lines of code, leading to frustration and inefficiency.
  • Initially explored various AI tools (ChatGPT, Claude, Gemini, Llama) for text extraction from PDFs, but found their accuracy lacking due to insufficient prompt specificity.

Overengineered System

  • Described the complex system created, which included:
    • Multiple parsing attempts with different tools.
    • A complicated workflow with three to four AI prompts to achieve desired data extraction.
    • Issues with accuracy due to varying PDF formats leading to brittle system performance.

Second Attempt

  • Shift to AI-first approach:
    • Simplified the system significantly by leveraging AI (particularly Gemini) for extracting data directly from PDFs, resulting in only about 1,200 lines of code.
  • Achieved significant improvements:
    • Cost: 99.6% savings using Gemini compared to Llama.
    • Accuracy: Improved extraction accuracy to around 99% for unknown formats.
    • Speed: Reduced processing time significantly.

Conclusion

  • Emphasized the importance of asking whether AI is capable of performing specific tasks before embarking on complex system builds.
  • Discussed future trends in AI, such as evolving prompt engineering and the potential of AI to guide user interactions instead of the other way around.
