Correction (overstated range). C3-B080-W16-01 says hardware floors stated by the vendors range from about 6 GB to 24 GB. The pinned Hunyuan3D-2.1 README states 10 GB for shape generation, 21 GB for texture generation and 29 GB for shape plus texture in total; TRELLIS.2 states at least 24 GB. So the upper end of the stated range is 29 GB for Hunyuan3D-2.1's full pipeline, not 24 GB. Hunyuan3D-2 (earlier) states 6 GB for shape and 16 GB total. Version/date. Pinned commits fetched 2026-10-23.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C3-B080-W16-01 from a discovery re-fetch on 2026-10-23; the curator re-located the cited excerpts by GET.

Limitations: Vendors may update figures; low-VRAM modes exist for some releases.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
