Apple M4 Max 128GB unified (MacBook Pro) for Local LLMs: VRAM and Model Fit
128 GB unified memory is unified memory, not discrete VRAM added to RAM: 137,438,953,472 bytes (128.00 GiB). The default system reserve is 12,884,901,888 bytes (12.00 GiB), and the net is 124,554,051,584 bytes (116.00 GiB).
Apple M4 Max 128GB unified (MacBook Pro): 128.00 GiB gross, default reserve 12.00 GiB, net calculator budget 116.00 GiB. Advertised 128 GB unified memory is treated as 128 GiB (2^30 bytes). Unified memory is a shared CPU/GPU pool; ~12 GiB default reserve covers macOS and other processes.

The reserve is a configurable calculator assumption, not a measured desktop tax. Headless systems can lower it after measuring baseline board usage.
Catalog fit at 8,192 tokens
Each row is the same automatic pick as the calculator at 8,192 tokens: the highest precision at or above 3 bits per weight that fits. A file under that floor stays available for a manual choice and is not the automatic row. Concurrent sequences = 1, FP16 KV. Fit and software support are separate. Format compatibility is not a verified run.
