1st promptCold start — includes initialization
>What is local AI inference?
Local AI inference means running an AI language model directly on your own hardware — your laptop, desktop, or server — instead of sending requests to a remote cloud API. When you run inference locally the model weights are loaded into your GPU or unified memory. Each token you generate requires reading those weights from memory, so memory bandwidth is the main bottleneck for decode speed. Key benefits of running locally: - Full privacy: your prompts never leave your machine - No per-token cost or rate limits - Works offline once the model is downloaded - Latency depends only on your hardware
2nd promptWarm — model ready, no init overhead
>How much VRAM do I need?
It depends on the model size and quantization level. A rough rule of thumb: Model size Q4 (4-bit) Q8 (8-bit) FP16 7B params ~4.3 GB ~7.5 GB ~14 GB 13B params ~7.9 GB ~13.9 GB ~26 GB 70B params ~42.7 GB ~74.9 GB ~140 GB Most people use 4-bit quantization (Q4_K_M) which gives 90-95% of full quality at a fraction of the memory. A 24 GB GPU can comfortably run most 7B-13B models.
Estimated: 4.6 tok/s decode · 42.5s TTFT (warm) · 11 tok/s prefill

What limits this setup

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.

Best improvement path

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 1.7 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions

Can MacBook Pro M2 Pro 32GB run Qwen3.5 35B A3B?

Yes, MacBook Pro M2 Pro 32GB can run Qwen3.5 35B A3B at Q3_K_S quantization (Very compromised (needs ~1.7 GB host RAM)). The recommended Q4_K_M requires 29.8 GB which exceeds available memory, but at Q3_K_S it needs only 25.6 GB. Expected decode speed: 6.4 tok/s.

How much VRAM does Qwen3.5 35B A3B need?

Qwen3.5 35B A3B (35B parameters) requires approximately 29.8 GB at Q4_K_M quantization. On MacBook Pro M2 Pro 32GB, it fits at Q3_K_S using 25.6 GB.

What is the best quantization for Qwen3.5 35B A3B?

The recommended quantization is Q4_K_M, but on MacBook Pro M2 Pro 32GB the best fitting quantization is Q3_K_S, which uses 25.6 GB.

What speed will Qwen3.5 35B A3B run at on MacBook Pro M2 Pro 32GB?

On MacBook Pro M2 Pro 32GB, Qwen3.5 35B A3B achieves approximately 6.4 tokens per second decode speed with a time-to-first-token of 30316ms using Q3_K_S quantization.

Can MacBook Pro M2 Pro 32GB run Qwen3.5 35B A3B for coding?

For coding workloads, Qwen3.5 35B A3B on MacBook Pro M2 Pro 32GB receives a F grade with 4.6 tok/s and 4K context.

What context window can Qwen3.5 35B A3B use on MacBook Pro M2 Pro 32GB?

On MacBook Pro M2 Pro 32GB, Qwen3.5 35B A3B 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.

What should I upgrade first if Qwen3.5 35B A3B feels slow on MacBook Pro M2 Pro 32GB?

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.

Is unified memory on MacBook Pro M2 Pro 32GB as fast as VRAM for Qwen3.5 35B A3B?

Not always. MacBook Pro M2 Pro 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.
