I Spent 10x Longer Debugging AI Code Than Writing It — Here's What Changed

Short summary

AI-generated code debugging often takes 10x longer than generation due to confident-but-wrong outputs, since LLMs lack context about your specific environment and error-handling conventions. The author debugged a pagination function for 45 minutes that took only 30 seconds to generate, revealing subtle logical errors and hallucinated API calls. Adopting test-first development, incremental requests, manual dependency verification, and consistent model versions reduced debugging overhead from 10x to 2-3x generation time.

• •AI-generated code debugging takes roughly 10x longer than generation because LLMs lack environmental context and write with unwarranted confidence
• •Concrete example: pagination function took 30 seconds to generate but 45 minutes to debug due to infinite loops and missing error handling
• •Four-step workflow (test-first development, incremental requests, manual API verification, consistent model versions) reduces debugging overhead from 10x to 2-3x

Generated with AI, which can make mistakes.
