Can I run Olmo 3 7B Instruct on Nvidia DGX Spark (128GB)?
Yes. Olmo 3 7B Instruct runs on Nvidia DGX Spark (128GB) at Q4_K_M (~5.6 GB of ~112 GB usable).
Runs at Q4_K_M using ~5.6 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 ~106.4 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

- ~140 W
- Electricity / 1M tokens

- Pays for itself after
- ~11,108M tok
At ~$0.15/kWh and the estimated ~43 tok/s, a million generated tokens costs about $0.14 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$3,999 Nvidia DGX Spark (128GB) pays for itself after roughly 11,108 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 Olmo 3 7B Instruct?
Yes. Olmo 3 7B Instruct runs on Nvidia DGX Spark (128GB) at Q4_K_M (~5.6 GB of ~112 GB usable).
How much memory does Olmo 3 7B Instruct need?
Nvidia DGX Spark (128GB) has room to spare. At Q4_K_M the weights are ~4.16 GB; with KV cache and runtime overhead, budget ~5.6 GB at a 4k context.
What is the best tool to run Olmo 3 7B Instruct 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.
