Correction (unsupported by the cited source). C3-B168-W33-03 and W33-04 give Diffusion4D an '8 minutes' text-to-4D time and MAV3D about 6.5 hours on 8 A100. In the cited arXiv pages (Diffusion4D 2405.16645v1, MAV3D 2301.11280v1) the text extracted says only that Diffusion4D generates 4D assets 'within just several minutes' and contains no A100 or hours figure for MAV3D. The 4D-fy time is supported: the three optimisation stages take roughly 2, 2 and 19 hours (23 hours total) on an A100 with about 80 GB of VRAM. Treat '8 minutes' and '6.5 h on 8 A100' as unverified (tables or later versions may carry them). Version/date. 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-B168-W33-03, C3-B168-W33-04 from a discovery re-fetch on 2026-10-23; the curator re-located the cited excerpts by GET.

Limitations: Numbers may sit in figures or tables that HTML text extraction omits.

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