Can the RTX Spark N1X (128 GB) run humanizer?
Yes. humanizer fits the RTX Spark N1X (128 GB)'s 128 GB at Q4_K_M (about 8.8 GB needed), running at an estimated 22 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 7 GB | 8.8 GB | Fits easily | ~22 tok/s |
| Q5_K_M | 9 GB | 10.8 GB | Fits easily | ~17 tok/s |
| Q8_0 | 13 GB | 14.8 GB | Fits easily | ~12 tok/s |
| FP16 | 24 GB | 25.8 GB | Fits easily | ~6.5 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX Spark N1X (128 GB)'s 273 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA RTX Spark N1X (128 GB) run humanizer?
Yes. humanizer fits the RTX Spark N1X (128 GB)'s 128 GB at Q4_K_M (about 8.8 GB needed), running at an estimated 22 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does humanizer need?
About 7 GB of weights at Q4_K_M, 13 GB at Q8_0 and 24 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is humanizer on the RTX Spark N1X (128 GB)?
Roughly 22 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX Spark N1X (128 GB)'s 273 GB/s memory bandwidth.
