Can I run Laguna XS 2.1 on Apple M5 (32GB)?
No. Laguna XS 2.1 needs ~22.2 GB even at Q4_K_M, but Apple M5 (32GB) only has ~21 GB usable.
Needs ~22.2 GB even at Q4_K_M, but only ~21 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 1.2 GB: Laguna XS 2.1 needs roughly 22.2 GB at Q4_K_M and Apple M5 (32GB) leaves only about 21 GB usable for a model. The lightest tracked hardware that runs Laguna XS 2.1 is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Laguna XS 2.1 on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can Apple M5 (32GB) run Laguna XS 2.1?
No. Laguna XS 2.1 needs ~22.2 GB even at Q4_K_M, but Apple M5 (32GB) only has ~21 GB usable.
How much memory does Laguna XS 2.1 need?
Apple M5 (32GB) does not have enough memory. At Q4_K_M the weights are ~20 GB; with KV cache and runtime overhead, budget ~22.2 GB at a 4k context. It is a Mixture-of-Experts model (33.4B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Laguna XS 2.1 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.
