Published video-model weights, licences and hardware notes

LongCat-Video: what the repository publishes

LongCat-Video publishes 13.6B parameters under the MIT License and states 720p output at 30fps. It states no GPU memory figure and names no card, so the one cell that decides whether the weights can be run on hardware somebody owns is empty. As of 2026-09-22.

Three questions, two of them answeredThe repository names MIT, states 13.6B parameters and states 720p at 30fps. It publishes no memory figure and names no card, so the question of whether the weights will run on hardware somebody owns cannot be answered from the repository at all.What can be settled from this repositoryWhat may I do with itMITA standard text, clearedonce and cleared for everyrelease carrying it.How big is the download13.6B parametersStated plainly, with novariant split to reconcile.Will it run on my cardNothing statedNo memory figure and nocard named, so the registerrecords none.Licence and size are cheap to publish
Fig. 1 The two cheap fields to publish are filled and the expensive one is empty, which is the most common shape of gap in this register.

The five fields this register keeps, for LongCat-Video. Read from the vendor's own repository on 2026-09-22.

Inclusion rule. The same five fields for every family here. A field the repository does not state is recorded as not stated rather than estimated from the parameter count. Order. Fixed field order, identical on every family page.

1Licence and size answered, cost unanswered

MIT and 13.6B are both one-line facts, quickly checked and quickly cleared. Neither tells a reader whether the model will load on the card in front of them, and the repository supplies nothing that does.

This is the most common shape of gap in this register, and it is worth stating as a pattern rather than as a complaint. A licence name and a parameter count are cheap to publish and interesting to announce. A memory figure requires running the thing and committing to a configuration, so it is the value most often left out.

2Minutes-long is a capability claim with no figure behind it

The repository describes the model as able to generate minutes-long videos and attaches no maximum to the phrase. The length cell therefore records that no ceiling is stated, rather than reading a number into an adjective.

The distinction matters because a ceiling is a commitment and an adjective is not. Three families here put an actual number on sixty seconds; a description of duration without a figure is a different kind of statement, and flattening the two into one column would make this register look more decided than it is.

3A 720p claim with nothing behind it in the next cell

720p at 30fps is the stated output, and nothing in the repository ties that output to a memory figure or to a card. So the resolution cell is filled and the hardware cell beside it is empty, which is the pairing a reader should treat most carefully.

An output size is the easiest value to publish and the least constraining, because it says what the code will emit rather than what emitting it costs. Read on its own it gets taken as evidence that the model is practical at that size, and this register keeps the two cells adjacent to make that harder to do.
