Yes — the Mac mini M4 Pro 64GB (64 GB LPDDR5X) can run gemma-4-26B-A4B-it. At Q4 with the default 8K context it needs ≈ 15.62 GB VRAM (weights 13.86 GB + KV cache 0.76 GB + 1 GB runtime overhead), which fits within 64 GB. Decode at Q4/8K: ≈ 45.7 tok/s (estimated, batch 1). FP16 (≈ 52.16 GB) also fits, at ≈ 12.6 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
