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: 8.0 tok/s decode · 24.2s TTFT (warm) · 20 tok/s prefill
What limits this setup
This setup is broadly balanced for this model.
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
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Frequently asked questions
Can MacBook Pro M4 32GB run Qwen3.5 27B?
Yes, MacBook Pro M4 32GB can run Qwen3.5 27B with a C grade (Runs with offload (needs ~0.7 GB host RAM)). Expected decode speed: 8.0 tok/s.
How much VRAM does Qwen3.5 27B need?
Qwen3.5 27B (27B parameters) requires approximately 24.0 GB of memory with Q4_K_M quantization.
What is the best quantization for Qwen3.5 27B?
The recommended quantization for Qwen3.5 27B is Q4_K_M, which balances quality and memory efficiency.
What speed will Qwen3.5 27B run at on MacBook Pro M4 32GB?
On MacBook Pro M4 32GB, Qwen3.5 27B achieves approximately 8.0 tokens per second decode speed with a time-to-first-token of 24194ms using Q4_K_M quantization.
Can MacBook Pro M4 32GB run Qwen3.5 27B for coding?
For coding workloads, Qwen3.5 27B on MacBook Pro M4 32GB receives a C grade with 8.0 tok/s and 11K context.
What context window can Qwen3.5 27B use on MacBook Pro M4 32GB?
On MacBook Pro M4 32GB, Qwen3.5 27B can safely use up to 11K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
What should I upgrade first if Qwen3.5 27B feels slow on MacBook Pro M4 32GB?
Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Is unified memory on MacBook Pro M4 32GB as fast as VRAM for Qwen3.5 27B?
Not always. MacBook Pro M4 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.
