Can I run SmolLM2 360M on Apple M5 (32GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~452 tok/s est.

Yes. SmolLM2 360M runs on Apple M5 (32GB) at Q4_K_M (~1.2 GB of ~21 GB usable).

Needs ~1.2 GB Device usable ~21 GB

Runs at Q4_K_M using ~1.2 GB of ~21 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M5 (32GB) leaves ~19.8 GB of headroom, room to step up to FP16 for higher quality.

FAQ

Can Apple M5 (32GB) run SmolLM2 360M?

Yes. SmolLM2 360M runs on Apple M5 (32GB) at Q4_K_M (~1.2 GB of ~21 GB usable).

How much memory does SmolLM2 360M need?

Apple M5 (32GB) has room to spare. At Q4_K_M the weights are ~0.271 GB; with KV cache and runtime overhead, budget ~1.2 GB at a 4k context.

What is the best tool to run SmolLM2 360M 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.
