what_fits_on_hardware — Rank which popular local LLMs fit on a given GPU or Apple Silicon Mac (at ~4-bit quantization, 8K context) — models that fit come first, biggest first, with max context each.
list_supported — List the built-in model names and hardware names this fit-checker knows (for mapping user wording to exact names).
