Can I run Laguna XS 2.1 on Nvidia DGX Spark (128GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated

Yes. Laguna XS 2.1 runs on Nvidia DGX Spark (128GB) at Q4_K_M (~22.2 GB of ~112 GB usable).

Needs ~22.2 GB Device usable ~112 GB

Runs at Q4_K_M using ~22.2 GB of ~112 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. Nvidia DGX Spark (128GB) leaves ~89.8 GB of headroom, room to step up to FP16 for higher quality.

FAQ

Can Nvidia DGX Spark (128GB) run Laguna XS 2.1?

Yes. Laguna XS 2.1 runs on Nvidia DGX Spark (128GB) at Q4_K_M (~22.2 GB of ~112 GB usable).

How much memory does Laguna XS 2.1 need?

Nvidia DGX Spark (128GB) has room to spare. 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 Linux?

Ollama for a simple setup; vLLM for the most speed. vLLM shines for multi-user serving/throughput. For a single local chat, Ollama or llama.cpp is simpler and lighter.

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.
