A 20-cent AI that can't write a sentence caught 13 requests our classifier missed

The author shares a counterintuitive experiment: a tiny model that can barely write a full sentence, tested for just 20 cents, caught 13 customer requests that their support classifier had missed, and raised the rate of ranking the correct source passage first from 60% to 90%. The takeaway: we may be using LLMs for the wrong jobs — many tasks don't need a fluent writer, and small specialized models can beat big ones on classification and retrieval ranking at a fraction of the cost.
