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: 16.4 tok/s decode · 11.8s TTFT (warm) · 41 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 Air M2 16GB run Solar 7B?
Yes, MacBook Air M2 16GB can run Solar 7B with a B grade (Tight fit). Expected decode speed: 15.2 tok/s.
How much VRAM does Solar 7B need?
Solar 7B (7B parameters) requires approximately 9.8 GB of memory with Q4_K_M quantization.
What is the best quantization for Solar 7B?
The recommended quantization for Solar 7B is Q4_K_M, which balances quality and memory efficiency.
What speed will Solar 7B run at on MacBook Air M2 16GB?
On MacBook Air M2 16GB, Solar 7B achieves approximately 15.2 tokens per second decode speed with a time-to-first-token of 12718ms using Q4_K_M quantization.
Can MacBook Air M2 16GB run Solar 7B for coding?
For coding workloads, Solar 7B on MacBook Air M2 16GB receives a B grade with 15.2 tok/s and 8K context.
What context window can Solar 7B use on MacBook Air M2 16GB?
On MacBook Air M2 16GB, Solar 7B 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 MacBook Air M2 16GB as fast as VRAM for Solar 7B?
Not always. MacBook Air M2 16GB 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.
