MPT-30B-Instruct needs ~48.0 GB but MacBook Pro M4 16GB only has 11.5 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 48.0 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, MPT-30B-Instruct requires more memory than MacBook Pro M4 16GB provides.
MPT-30B-Instruct (30B parameters) requires approximately 48.0 GB of memory with Q5_K_M quantization.
The recommended quantization for MPT-30B-Instruct is Q5_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 16GB, MPT-30B-Instruct achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q5_K_M quantization.
For coding workloads, MPT-30B-Instruct on MacBook Pro M4 16GB receives a F grade with 2.0 tok/s and 4K context.
On MacBook Pro M4 16GB, MPT-30B-Instruct can safely use up to 4K tokens of context. The model's official context limit is 8K, 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 Pro M4 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.
