Can I run LFM2 700M on Nvidia DGX Spark (128GB)?
Yes. LFM2 700M runs on Nvidia DGX Spark (128GB) at Q4_K_M (~1.9 GB of ~112 GB usable).
Runs at Q4_K_M using ~1.9 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 ~110.1 GB of headroom, room to step up to FP16 for higher quality.

Which quant fits
Running cost · estimate
- Power draw
- ~140 W
- Electricity / 1M tokens
- ~$0.03
- Pays for itself after
- ~8,509M tok
At ~$0.15/kWh and the estimated ~193 tok/s, a million generated tokens costs about $0.03 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$3,999 Nvidia DGX Spark (128GB) pays for itself after roughly 8,509 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 Nvidia DGX Spark (128GB) run LFM2 700M?
Yes. LFM2 700M runs on Nvidia DGX Spark (128GB) at Q4_K_M (~1.9 GB of ~112 GB usable).
How much memory does LFM2 700M need?
Nvidia DGX Spark (128GB) has room to spare. At Q4_K_M the weights are ~0.92 GB; with KV cache and runtime overhead, budget ~1.9 GB at a 4k context.
What is the best tool to run LFM2 700M 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.
