Can I run Devstral Small on Apple M4 (24GB)?
Yes. Devstral Small runs on Apple M4 (24GB) at Q4_K_M (~15.4 GB of ~16 GB usable).
Fits at Q4_K_M (~15.4 GB of ~16 GB usable) but with little headroom. Close other apps, or drop to a 2k context to free about a gigabyte.
That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 (24GB) leaves ~0.6 GB of headroom.

At ~$0.15/kWh and the estimated ~7 tok/s, a million generated tokens costs about $0.39 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,299 Apple M4 (24GB) pays for itself after roughly 11,809 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ
Can Apple M4 (24GB) run Devstral Small?
Yes. Devstral Small runs on Apple M4 (24GB) at Q4_K_M (~15.4 GB of ~16 GB usable).
How much memory does Devstral Small need?
It is a tight fit on Apple M4 (24GB). At Q4_K_M the weights are ~13.35 GB; with KV cache and runtime overhead, budget ~15.4 GB at a 4k context.
What is the best tool to run Devstral Small 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.
