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: 60.4 tok/s decode · 3.2s TTFT (warm) · 151 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.

Yes, MacBook Pro M3 Max 48GB can run Samantha 7B with a B grade (Runs well). Expected decode speed: 60.4 tok/s.

How much VRAM does Samantha 7B need?

Samantha 7B (7B parameters) requires approximately 12.3 GB of memory with Q4_K_M quantization.

What is the best quantization for Samantha 7B?

The recommended quantization for Samantha 7B is Q4_K_M, which balances quality and memory efficiency.

What speed will Samantha 7B run at on MacBook Pro M3 Max 48GB?

On MacBook Pro M3 Max 48GB, Samantha 7B achieves approximately 60.4 tokens per second decode speed with a time-to-first-token of 3204ms using Q4_K_M quantization.

Can MacBook Pro M3 Max 48GB run Samantha 7B for coding?

For coding workloads, Samantha 7B on MacBook Pro M3 Max 48GB receives a B grade with 60.4 tok/s and 4K context.

What context window can Samantha 7B use on MacBook Pro M3 Max 48GB?

On MacBook Pro M3 Max 48GB, Samantha 7B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.

Is unified memory on MacBook Pro M3 Max 48GB as fast as VRAM for Samantha 7B?

Not always. MacBook Pro M3 Max 48GB 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.
