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.
| Model quality | 33.5 / 45 | |
|---|---|---|
| Memory fit | 23.0 / 25 | |
| Speed | 6.3 / 15 | |
| Memory use | 15.0 / 15 | |

Quick answers
How much memory does FLUX.1 [dev] need on the NVIDIA RTX 2000 Ada Generation 16GB?
At NF4 it needs about 14.4 GB. The NVIDIA RTX 2000 Ada Generation 16GB has 16.0 GB usable.
How long does FLUX.1 [dev] take on the NVIDIA RTX 2000 Ada Generation 16GB?
About 56 s per image at NF4 and default settings, an estimate scaled from a reference timing by this hardware’s compute speed.
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.
