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 Air M4 24GB can run Phi-4 Mini Reasoning 4B with a S grade (Runs well). Expected decode speed: 36.9 tok/s.
Phi-4 Mini Reasoning 4B (3.799999952316284B parameters) requires approximately 7.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Phi-4 Mini Reasoning 4B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Air M4 24GB, Phi-4 Mini Reasoning 4B achieves approximately 36.9 tokens per second decode speed with a time-to-first-token of 5252ms using Q4_K_M quantization.
For coding workloads, Phi-4 Mini Reasoning 4B on MacBook Air M4 24GB receives a S grade with 36.9 tok/s and 125K context.
On MacBook Air M4 24GB, Phi-4 Mini Reasoning 4B can safely use up to 125K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
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.
