Can the DGX Spark (GB10) run OTel-2.0-LLM-31B-IT-QLoRA?
Yes. OTel-2.0-LLM-31B-IT-QLoRA fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 19.8 GB needed), running at an estimated 8.7 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 18 GB | 19.8 GB | Fits easily | ~8.7 tok/s |
| Q5_K_M | 22 GB | 23.8 GB | Fits easily | ~7.1 tok/s |
| Q8_0 | 33 GB | 34.8 GB | Fits easily | ~4.8 tok/s |
| FP16 | 63 GB | 64.8 GB | Fits easily | ~2.5 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the DGX Spark (GB10)'s 273.2 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.
