Two 2B releases, opposite disclosure
Cosmos Predict 2.5 states 32.54 GB of GPU VRAM on Ampere, Hopper or Blackwell. Stable Video Diffusion states about 180s on an A100 80GB card and no memory figure. Both are 2B releases. As of 2026-09-22.

| Hardware, as each vendor states it | 32.54 GB of GPU VRAM | About 180s on an A100 80GB card |
| The detail published beside it | Ampere, Hopper and Blackwell named as supported | A timing on a named card; no memory floor stated |
| Resolution, from the same pages | 720P | 576x1024 |
| Length, from the same pages | A 5-second clip | 25 frames, 4sec or less |
Inclusion rule. Two families whose published values in this column lead to opposite decisions. A pair that happens to agree is not listed, because agreement is already visible on the column summary. Order. The column itself first, then its detail, then the columns that qualify it.
1The pair disproves the arithmetic
Two billion parameters in half precision is roughly four gigabytes of weights. One of these cards says the run needs over thirty-two, and the other declines to say. Neither matches the arithmetic.
Anyone estimating a requirement from a count would be wrong by a factor of eight on the row that publishes a figure, and would have nothing to check against on the other.
2A timing and a floor serve different readers
For a team costing a render farm, 180s on an A100 is the more valuable number. For somebody with one desktop card it is unusable, and the 32.54 GB figure is exactly what they need.
The register keeps both in the hardware column because both are what the vendor published there, and marks which kind of statement each one is.
3Precision is not the same as scope
Two decimal places on a memory figure is the most precise value in the register, and it still describes one configuration: 720P, 16FPS, five seconds.
The SVD card describes its output fully too, at 576x1024 and 25 frames. The difference between the rows is not documentation effort in general; it is this one column.
