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: 12.7 tok/s decode · 15.3s TTFT (warm) · 32 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 Mac Studio M3 Ultra 96GB run BaichuanMed OCR 72B i1?
Yes, Mac Studio M3 Ultra 96GB can run BaichuanMed OCR 72B i1 with a C grade (Tight fit). Expected decode speed: 12.7 tok/s.
How much VRAM does BaichuanMed OCR 72B i1 need?
BaichuanMed OCR 72B i1 (72B parameters) requires approximately 63.6 GB of memory with Q4_K_M quantization.
What is the best quantization for BaichuanMed OCR 72B i1?
The recommended quantization for BaichuanMed OCR 72B i1 is Q4_K_M, which balances quality and memory efficiency.
What speed will BaichuanMed OCR 72B i1 run at on Mac Studio M3 Ultra 96GB?
On Mac Studio M3 Ultra 96GB, BaichuanMed OCR 72B i1 achieves approximately 12.7 tokens per second decode speed with a time-to-first-token of 15268ms using Q4_K_M quantization.
Can Mac Studio M3 Ultra 96GB run BaichuanMed OCR 72B i1 for coding?
For coding workloads, BaichuanMed OCR 72B i1 on Mac Studio M3 Ultra 96GB receives a C grade with 12.7 tok/s and 26K context.
What context window can BaichuanMed OCR 72B i1 use on Mac Studio M3 Ultra 96GB?
On Mac Studio M3 Ultra 96GB, BaichuanMed OCR 72B i1 can safely use up to 26K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
What should I upgrade first if BaichuanMed OCR 72B i1 feels slow on Mac Studio M3 Ultra 96GB?
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 Mac Studio M3 Ultra 96GB as fast as VRAM for BaichuanMed OCR 72B i1?
Not always. Mac Studio M3 Ultra 96GB 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.
