1st promptCold start — includes initialization
>Solve: If a train travels at 60 mph for 2.5 hours, how far does it go?
Let me work through this step by step.

Given information:
  - Speed = 60 mph (miles per hour)
  - Time  = 2.5 hours

Formula: Distance = Speed x Time

Calculation:
  Distance = 60 mph x 2.5 h
           = 150 miles

The train travels 150 miles.

Double-check: at 60 mph the train covers 60 miles each hour. In half an hour it covers 30 miles. So in 2.5 hours: 60 + 60 + 30 = 150 miles. Confirmed.
2nd promptWarm — model ready, no init overhead
>What if the train stops for 20 minutes halfway?
The stop doesn't change the total distance covered while moving, but it affects total trip time.

Breakdown:
  - First half: 1.25 hours at 60 mph = 75 miles
  - Stop: 20 minutes (no distance)
  - Second half: 1.25 hours at 60 mph = 75 miles

Total distance: 150 miles (same)
Total time: 2.5 h + 0.33 h = 2.83 hours
Average speed: 150 / 2.83 = 53 mph

The distance stays the same but average speed drops to 53 mph because of the stop.
Estimated: 15.3 tok/s decode · 12.7s TTFT (warm) · 38 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 MacBook Pro M4 Max 96GB run Llama 3.1 70B?

Yes, MacBook Pro M4 Max 96GB can run Llama 3.1 70B with a A grade (Tight fit). Expected decode speed: 15.3 tok/s.

How much VRAM does Llama 3.1 70B need?

Llama 3.1 70B (70B parameters) requires approximately 58.9 GB of memory with Q4_K_M quantization.

What is the best quantization for Llama 3.1 70B?

The recommended quantization for Llama 3.1 70B is Q4_K_M, which balances quality and memory efficiency.

What speed will Llama 3.1 70B run at on MacBook Pro M4 Max 96GB?

On MacBook Pro M4 Max 96GB, Llama 3.1 70B achieves approximately 15.3 tokens per second decode speed with a time-to-first-token of 12657ms using Q4_K_M quantization.

Can MacBook Pro M4 Max 96GB run Llama 3.1 70B for coding?

For coding workloads, Llama 3.1 70B on MacBook Pro M4 Max 96GB receives a A grade with 15.3 tok/s and 50K context.

What context window can Llama 3.1 70B use on MacBook Pro M4 Max 96GB?

On MacBook Pro M4 Max 96GB, Llama 3.1 70B can safely use up to 50K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.

Is unified memory on MacBook Pro M4 Max 96GB as fast as VRAM for Llama 3.1 70B?

Not always. MacBook Pro M4 Max 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.
