Offload
40%
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 1.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, MacBook Air M4 24GB can run Baichuan M2 32B Q4 K M at Q2_K quantization (Very compromised (needs ~1.5 GB host RAM)). The recommended Q4_K_M requires 26.8 GB which exceeds available memory, but at Q2_K it needs only 19.7 GB. Expected decode speed: 8.6 tok/s.
Baichuan M2 32B Q4 K M (32B parameters) requires approximately 26.8 GB at Q4_K_M quantization. On MacBook Air M4 24GB, it fits at Q2_K using 19.7 GB.
The recommended quantization is Q4_K_M, but on MacBook Air M4 24GB the best fitting quantization is Q2_K, which uses 19.7 GB.
On MacBook Air M4 24GB, Baichuan M2 32B Q4 K M achieves approximately 8.6 tokens per second decode speed with a time-to-first-token of 22510ms using Q2_K quantization.
For coding workloads, Baichuan M2 32B Q4 K M on MacBook Air M4 24GB receives a F grade with 4.5 tok/s and 4K context.
On MacBook Air M4 24GB, Baichuan M2 32B Q4 K M can safely use up to 6K tokens of context at Q2_K 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 Air M4 24GB 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.
