On a 128 GB Mac, 12 catalog models run fully on the GPU at an 8,192-token context. The most capable is Qwen3-235B-A22B-Instruct-2507 at UD-Q2_K_XL (needs ~93.1 GiB). Pick a smaller model or a lower quant for more headroom.
Figures assume a 128 GB unified-memory Mac (one pool shared by CPU and GPU), judged at an 8,192-token context. Speeds depend on the specific chip — see the GPU pages.

Derived live from the fit engine + catalog at an 8,192-token context. "Fits in" is the modelled VRAM the sweet-spot quant needs (weights + KV cache + overhead). Speed depends on your specific card — check a GPU page or the calculator.
