Read from: the kind of page each cell was taken off

Read from is the row naming the sort of document a statement was taken off. The entries in this record divide between plan tables written for buyers and technical documents written for engineers, and the two carry very different weight. As of 2026-09-12.

Inclusion rule. Every generator entry in this record, with the page type its own source line names. Only pages published by the vendor itself qualify; reviews and coverage do not. Order. Alphabetical by generator name.

1A plan table and a system card are not the same evidence

Five entries here rest on a page whose job is to sell a subscription. A feature appears in a list, or it does not, and the reader infers the rest. Nothing on such a page was written to state a position about marking, and the inference carries exactly as much weight as an omission from a summary usually does.

Four entries rest on the opposite kind of document: a system card, a service card, a research publication, a reference for callers. Those pages exist to describe behaviour precisely, and their sentences can be quoted without inferring anything. The record keeps both, marks which is which, and never promotes a plan omission into a published statement.

2One vendor was read twice, and the second reading is the finding

The single entry with two page types is the one whose model weights are published as well as hosted. The API reference describes an optional flag that puts a corner mark on a rendered video. The repository, where anybody can take the weights and run them without touching that API, was read for anything asking a downstream operator to mark output, and the cell records that nothing of the kind was found.

That pair matters for a provider duty far more than either reading does alone. A flag in a hosted interface reaches whoever calls the interface. Weights that have left the building reach whoever downloaded them, and the marking question follows the weights rather than the flag.

3Why the page type stays on the record instead of being levelled out

It would be neater to drop this row and let every statement look alike. It would also be misleading: the reason several cells in the machine-readable column read as not documented is that a pricing page had no reason to mention a manifest, not that the vendor considered the question and declined.

Keeping the page type visible lets a reader discount the cells that deserve discounting without this record doing the discounting for them. The same discipline puts the address and the reading date under every entry, so a page rewritten since can be held against what it said at the time.
