What Consumer Hardware Actually Does
Twenty-nine local-model labs over three months on hardware anyone could buy — 12 GB NVIDIA cards and a dual Intel Arc Pro B70 machine. What a 30B mixture-of-experts model really runs at, why a 120B is serviceable on consumer cards, the one flag worth 7× on a 70B, and a LoRA fine-tune that trained on an Intel GPU and re-served itself in six seconds. Plus the context cliff, the memory constraint that actually binds (it isn't VRAM), and the head-to-head where local output outscored frontier cloud. Retractions, unresolved contradictions and traps included — among them a server that silently truncates your prompt and reports success.
