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.

Inference speed
Estimated decode speed (tokens/sec) for Mistral Nemo 12B at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~168 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, MacBook Pro M3 24GB can run Mistral Nemo 12B with a B grade (Runs well). Expected decode speed: 10.0 tok/s.
Mistral Nemo 12B (12B parameters) requires approximately 13.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Mistral Nemo 12B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 24GB, Mistral Nemo 12B achieves approximately 10.0 tokens per second decode speed with a time-to-first-token of 19386ms using Q4_K_M quantization.
For coding workloads, Mistral Nemo 12B on MacBook Pro M3 24GB receives a B grade with 10.0 tok/s and 42K context.
On MacBook Pro M3 24GB, Mistral Nemo 12B can safely use up to 42K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 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.
