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: 24.5 tok/s decode · 7.9s TTFT (warm) · 61 tok/s prefill
What limits this setup
This setup is broadly balanced for this model.
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.

Frequently asked questions
Can Mac Studio M1 Ultra 64GB run Aya Expanse 32B?
Yes, Mac Studio M1 Ultra 64GB can run Aya Expanse 32B with a B grade (Runs well). Expected decode speed: 24.5 tok/s.
How much VRAM does Aya Expanse 32B need?
Aya Expanse 32B (32B parameters) requires approximately 29.8 GB of memory with Q4_K_M quantization.
What is the best quantization for Aya Expanse 32B?
The recommended quantization for Aya Expanse 32B is Q4_K_M, which balances quality and memory efficiency.
What speed will Aya Expanse 32B run at on Mac Studio M1 Ultra 64GB?
On Mac Studio M1 Ultra 64GB, Aya Expanse 32B achieves approximately 24.5 tokens per second decode speed with a time-to-first-token of 7898ms using Q4_K_M quantization.
Can Mac Studio M1 Ultra 64GB run Aya Expanse 32B for coding?
For coding workloads, Aya Expanse 32B on Mac Studio M1 Ultra 64GB receives a B grade with 24.5 tok/s and 8K context.
What context window can Aya Expanse 32B use on Mac Studio M1 Ultra 64GB?
On Mac Studio M1 Ultra 64GB, Aya Expanse 32B can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Is unified memory on Mac Studio M1 Ultra 64GB as fast as VRAM for Aya Expanse 32B?
Not always. Mac Studio M1 Ultra 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.
