Can I run Granite 4.1 30B on Apple M4 (24GB)?
No. Granite 4.1 30B needs ~19.1 GB even at Q4_K_M, but Apple M4 (24GB) only has ~16 GB usable.
Needs ~19.1 GB even at Q4_K_M, but only ~16 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 3.1 GB: Granite 4.1 30B needs roughly 19.1 GB at Q4_K_M and Apple M4 (24GB) leaves only about 16 GB usable for a model. The lightest tracked hardware that runs Granite 4.1 30B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Granite 4.1 30B on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can Apple M4 (24GB) run Granite 4.1 30B?
No. Granite 4.1 30B needs ~19.1 GB even at Q4_K_M, but Apple M4 (24GB) only has ~16 GB usable.
How much memory does Granite 4.1 30B need?
Apple M4 (24GB) does not have enough memory. At Q4_K_M the weights are ~17 GB; with KV cache and runtime overhead, budget ~19.1 GB at a 4k context.
What is the best tool to run Granite 4.1 30B on macOS?
LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
