Show HN: Qwen3-4B with the AI writing tics trained out

A small open model called Qwen3-4B has been fine-tuned on a MacBook Air to remove common AI writing tics such as em dashes, "not X, but Y" constructions, and lists of three, operating without a system prompt. The model's performance is evaluated on 40 held-out prompts, with details provided on the training rounds and instructions for running it.
