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 Qwen3.5 9B with a C grade (Runs well). Expected decode speed: 14.5 tok/s.
Qwen3.5 9B (9B parameters) requires approximately 10.0 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen3.5 9B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Air M4 24GB, Qwen3.5 9B achieves approximately 14.5 tokens per second decode speed with a time-to-first-token of 13371ms using Q4_K_M quantization.
For coding workloads, Qwen3.5 9B on MacBook Air M4 24GB receives a C grade with 14.5 tok/s and 126K context.
On MacBook Air M4 24GB, Qwen3.5 9B can safely use up to 126K tokens of context. The model's official context limit is —, 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.
