MinHash Pitfalls: Developers Discuss Using LLMs to Review Tricky Code Bugs
giffmana · x · 2026-07-24
While rebuilding a data deduplication pipeline, a developer discovered a hidden bug in the previous version: the MinHash tokenizer mistakenly used \W instead of \W+. This caused the 5-gram features of C++ code to be filled with empty strings, meaning almost all high-level languages shared the exact same invalid features.
In response, another tech community member asked: Have you tried using an LLM to review the buggy code? He suggested that current LLMs should be quite capable of catching these subtle logic errors that are notoriously difficult for humans to spot visually.
