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

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 M4 24GB run Qwen 3 14B?

Yes, MacBook Air M4 24GB can run Qwen 3 14B with a S grade (Tight fit). Expected decode speed: 9.6 tok/s.

How much VRAM does Qwen 3 14B need?

Qwen 3 14B (14B parameters) requires approximately 14.5 GB of memory with Q4_K_M quantization.

What is the best quantization for Qwen 3 14B?

The recommended quantization for Qwen 3 14B is Q4_K_M, which balances quality and memory efficiency.

What speed will Qwen 3 14B run at on MacBook Air M4 24GB?

On MacBook Air M4 24GB, Qwen 3 14B achieves approximately 9.6 tokens per second decode speed with a time-to-first-token of 20135ms using Q4_K_M quantization.

Can MacBook Air M4 24GB run Qwen 3 14B for coding?

For coding workloads, Qwen 3 14B on MacBook Air M4 24GB receives a S grade with 9.6 tok/s and 34K context.

What context window can Qwen 3 14B use on MacBook Air M4 24GB?

On MacBook Air M4 24GB, Qwen 3 14B can safely use up to 34K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.

Is unified memory on MacBook Air M4 24GB as fast as VRAM for Qwen 3 14B?

Not always. MacBook Air M4 24GB 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.
