Offload
10%
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 1.0 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, MacBook Pro M2 Max 32GB can run Baichuan 13B with a B grade (Very compromised (needs ~1 GB host RAM)). Expected decode speed: 20.9 tok/s.
Baichuan 13B (13B parameters) requires approximately 25.9 GB of memory with Q5_K_M quantization.
The recommended quantization for Baichuan 13B is Q5_K_M, which balances quality and memory efficiency.
On MacBook Pro M2 Max 32GB, Baichuan 13B achieves approximately 20.9 tokens per second decode speed with a time-to-first-token of 9255ms using Q5_K_M quantization.
For coding workloads, Baichuan 13B on MacBook Pro M2 Max 32GB receives a B grade with 20.9 tok/s and 8K context.
On MacBook Pro M2 Max 32GB, Baichuan 13B can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.

Not always. MacBook Pro M2 Max 32GB 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.
