Hardware requirements and grades
Thumper checks each buyer's computer against the requirements you set and shows the result on your listing. Leave video memory empty and every buyer sees Not graded.

How the grade is worked out
Grades use video memory and the graphics backends you list (CUDA, ROCm, Metal, Vulkan, DirectML). Up to 90% of the card is “with headroom”, up to 100% fits, and more than that runs slower by borrowing the computer's memory.
Minimum sets the grade; recommended is shown next to it. Video memory is at least 1 GB and at most 500 GB.
Fixing Not graded
Open your repository's Settings › Hardware requirements and add the numbers from your readme or model card, not a guess. If you don't know a value, leave it empty and buyers see “not stated”.
Saving takes effect for buyers right away. No new version is needed.
