HunyuanVideo: what the repository publishes

HunyuanVideo publishes weights for a model of over 13 billion parameters under a licence the vendor wrote itself rather than a standard permissive one. The repository states 60GB of peak GPU memory at its larger setting, measured on a single 80G card. As of 2026-09-12.

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.

1A vendor-written licence is a different thing from Apache 2.0

Nine of the 15 families in this register carry a licence whose text is standard and whose terms a reader has cleared once and for all. This one carries a licence named after the company that wrote it, which means the terms have to be read rather than assumed.

This register records the licence name and does not summarise its terms. A one-line paraphrase of a bespoke licence is exactly the kind of helpfulness that turns into somebody relying on a wrong reading, and the licence file is one click from the row.

2The memory figures are stated per setting, which is unusually clear

Sixty gigabytes at the larger resolution and frame count, forty-five at the smaller. Most repositories publish one number or none; publishing two with the settings attached lets a reader work out which side of a hardware boundary their intended output falls on.

Both figures sit well above anything a desktop card offers, so this family is a rented-server proposition rather than a local one on the published evidence.

3What the register does not carry for this family

No hosted service in this register names this model on a priced page, so there is no seconds rate to set against the hardware. That leaves the cost comparison open in one direction: the hardware cost is knowable and the alternative is not.

The row will appear if a service starts naming it. Until then the family sits in this register as published weights with no commercial counterpart to compare against.

4The same field, across every family

Inclusion rule. Families whose vendor has published weights openly. A family whose repository does not state this particular field keeps its row, marked hollow. Order. Alphabetical by family name.

5Open weights, hosted

Instead of local hardware for “HunyuanVideo”, SceneMixer runs hosted models; its guides describe the result:

Typically 60–120 seconds, always 9:16 vertical, ending on a hook. SceneMixer's episode outlines are generated with that pacing, and setting a project to 9:16 makes every segment vertical (the default is 16:9).

Doubao Seed 2.1 Pro is the family’s full-size tier at 100% of the base text rate, twice the default. Same three jobs — reading, writing, storyboards — with more headroom on long, crowded episodes: it holds the storyboard’s strict format more reliably and keeps track of many characters and locations in one pass.
