105 more models in the catalog do not fit this default profile, or ranked below the first 40 that do.

Example: Runs fully in unified memory on your Apple M1 Max at Q5_K_M, 8K context, about 11–14 tok/s. Weights 18.8 GB plus 0.57 GB of KV cache — 19.9 GB of 24.0 GB usable. Up to 64K context still fits. Weights shown in the verdict use GiB (the same 1024³ counting as GPU memory).
