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.

What limits this setup

It fits through host-memory offload, and offload is the main reason performance drops.

CPU or host-memory offload is active

About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.

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

Remove offload with more accelerator memory

Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.

Buy headroom, not only minimum fit

A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Increase host RAM if you keep offloading

This setup may need roughly 6.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions

Can MacBook Pro M2 Max 96GB run Pixtral Large 124B?

Yes, MacBook Pro M2 Max 96GB can run Pixtral Large 124B at Q3_K_S quantization (Very compromised (needs ~6.5 GB host RAM)). The recommended Q4_K_M requires 92.3 GB which exceeds available memory, but at Q3_K_S it needs only 77.4 GB. Expected decode speed: 3.2 tok/s.

How much VRAM does Pixtral Large 124B need?

Pixtral Large 124B (124B parameters) requires approximately 92.3 GB at Q4_K_M quantization. On MacBook Pro M2 Max 96GB, it fits at Q3_K_S using 77.4 GB.

What is the best quantization for Pixtral Large 124B?

The recommended quantization is Q4_K_M, but on MacBook Pro M2 Max 96GB the best fitting quantization is Q3_K_S, which uses 77.4 GB.

What speed will Pixtral Large 124B run at on MacBook Pro M2 Max 96GB?

On MacBook Pro M2 Max 96GB, Pixtral Large 124B achieves approximately 3.2 tokens per second decode speed with a time-to-first-token of 60203ms using Q3_K_S quantization.

Can MacBook Pro M2 Max 96GB run Pixtral Large 124B for coding?

For coding workloads, Pixtral Large 124B on MacBook Pro M2 Max 96GB receives a F grade with 2.2 tok/s and 4K context.

What context window can Pixtral Large 124B use on MacBook Pro M2 Max 96GB?

On MacBook Pro M2 Max 96GB, Pixtral Large 124B can safely use up to 4K tokens of context at Q3_K_S quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.

What should I upgrade first if Pixtral Large 124B feels slow on MacBook Pro M2 Max 96GB?

Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.

Is unified memory on MacBook Pro M2 Max 96GB as fast as VRAM for Pixtral Large 124B?

Not always. MacBook Pro M2 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.
