Finetuned 1.5B Qwen hits GPT-4o-level bash generation with 400k synthetic examples, fully open-sourced

A hobby project finetuned a 1.5B Qwen model on 400k synthetic examples to generate bash commands at near GPT-4o level, using a mostly automated training pipeline. The author has open-sourced everything: the full synthetic dataset (dirac-run/ec-training-data on Hugging Face), GGUF models at 1.5B and 0.6B sizes, and a companion CLI tool on GitHub, inviting anyone to train on or reuse the data. It shows how far small models can be pushed on vertical tasks with synthetic data.
