Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 92.1 GB, but this setup only exposes 11.5 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, Mixtral 8x22B requires more memory than MacBook Air M2 16GB provides.
Mixtral 8x22B (141B parameters) requires approximately 92.1 GB of memory with Q4_K_M quantization.
The recommended quantization for Mixtral 8x22B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Air M2 16GB, Mixtral 8x22B achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
For coding workloads, Mixtral 8x22B on MacBook Air M2 16GB receives a F grade with 2.0 tok/s and 4K context.
On MacBook Air M2 16GB, Mixtral 8x22B can safely use up to 4K tokens of context. The model's official context limit is 66K, but available memory constrains the safe maximum.

Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
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.
