The instruction-tuned release of Quartz Micro Preview Base — the same ~1B-parameter mixture-of-experts model, trained completely from scratch on a single consumer GPU, now given a full-parameter supervised fine-tune so it follows instructions instead of just completing text. This is a preview, not a finished product. It is small on every axis by design, and its evaluation below is reported honestly, including where it still falls short — that's this project's standing practice, not a disclaimer added after the fact. - Full-parameter SFT, not LoRA — the base model has zero instruction-following behavior, so a light adapter touch isn't the right tool; every parameter was updated.…
