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, Mac mini M2 24GB can run Pixtral 12B with a A grade (Runs well). Expected decode speed: 8.9 tok/s.
Pixtral 12B (12B parameters) requires approximately 13.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Pixtral 12B is Q4_K_M, which balances quality and memory efficiency.
On Mac mini M2 24GB, Pixtral 12B achieves approximately 8.9 tokens per second decode speed with a time-to-first-token of 21802ms using Q4_K_M quantization.
For coding workloads, Pixtral 12B on Mac mini M2 24GB receives a A grade with 8.9 tok/s and 42K context.
On Mac mini M2 24GB, Pixtral 12B can safely use up to 42K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Not always. Mac mini M2 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.
