Ollama

Not in the Ollama library yet. Mainline llama.cpp (which Ollama and LM Studio build on) does not support the Dory architecture yet, so NVIDIA’s GGUF needs a llama.cpp build from PR #30306. vLLM has merged support (PR #60149).

How it’s rated

Quality 68Good quality (B) · 68 of 100: how capable the model is at F16, whatever it runs on. Match score 73/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at F16, from its editorial quality tier scaled by the quantization or precision. It’s the same on any hardware that runs this variant. Scale: A+ 85+ · A 70+ · B 55+ · C 40+ · D under 40.
Runs Runs great
How well it runs on the Apple M5 Ultra (256 GB): speed, capped by how well it fits in memory. Runs great: 30+ tokens/s (or near the image, video or decision speed target) · Runs well: 10+ tokens/s · Slow: 3+ tokens/s · Very slow: under 3 · Won’t run: doesn’t fit even with offload. A tight fit or RAM offload caps it at Runs well; heavy offload caps it at Slow.

Match score

To order lists, each result also gets a match score out of 100 from four parts. It favors the most capable model that still runs well.

Quick answers

How much memory does Nemotron Labs Dory 1.0 4B need on the M5 Ultra 256GB?

At F16 it needs about 24.4 GB. The M5 Ultra 256GB has 192 GB usable.

How fast is Nemotron Labs Dory 1.0 4B on the M5 Ultra 256GB?

About 74.8 tok/s at F16, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Nemotron Labs Dory 1.0 4B should I use on the M5 Ultra 256GB?

F16. Of the versions that fit, it is the one that runs best; when two run equally well, the check prefers the higher-rated one.

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
