Offload
20%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 3.7 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, MacBook Pro M4 Pro 64GB can run BaichuanMed OCR 72B i1 at Q3_K_S quantization (Very compromised (needs ~3.7 GB host RAM)). The recommended Q4_K_M requires 60.2 GB which exceeds available memory, but at Q3_K_S it needs only 51.5 GB. Expected decode speed: 8.3 tok/s.
BaichuanMed OCR 72B i1 (72B parameters) requires approximately 60.2 GB at Q4_K_M quantization. On MacBook Pro M4 Pro 64GB, it fits at Q3_K_S using 51.5 GB.
The recommended quantization is Q4_K_M, but on MacBook Pro M4 Pro 64GB the best fitting quantization is Q3_K_S, which uses 51.5 GB.
On MacBook Pro M4 Pro 64GB, BaichuanMed OCR 72B i1 achieves approximately 8.3 tokens per second decode speed with a time-to-first-token of 23266ms using Q3_K_S quantization.
For coding workloads, BaichuanMed OCR 72B i1 on MacBook Pro M4 Pro 64GB receives a F grade with 5.9 tok/s and 4K context.
On MacBook Pro M4 Pro 64GB, BaichuanMed OCR 72B i1 can safely use up to 6K tokens of context at Q3_K_S quantization. The model's official context limit is —, but available memory constrains the safe maximum.
Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Not always. MacBook Pro M4 Pro 64GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
