Is HelixWorld on Sume? No: a preview checkpoint, no hosted API
HelixWorld, Noiz AI's interactive video-and-stereo-audio model, ships as weights and a browser demo. Sume lists no id for it; these rows return sound.
No, HelixWorld is not on Sume. Noiz AI released it on 2026-10-12 as a preview checkpoint on Hugging Face with code on GitHub, and its repository mentions no hosted API, only a browser demo at helixworld.org. Sume's Video Router lists no HelixWorld id, so a request naming it would not resolve. If you need a clip with sound today, pick a catalog row that makes audio.
Facts about HelixWorld come from its GitHub page and the nocode.mba October tracker, both read 2026-10-14. Facts about Sume come from the Video Router docs page, read the same day.
What is HelixWorld, in the vendor's words?
The repository calls it a real-time interactive audio-visual world model: it generates video and spatial stereo audio together from a starting image, steered by camera movement and keyboard input. That is a different product shape from a prompt-to-clip API, where you submit once and fetch a finished file.

Which Sume rows return sound instead?
Two rows in the Video Router table state audio with no toggle: minimax-h3 and minimax-h3-max both list native stereo audio, 5 to 15 seconds, and gemini-omni-flash-1.1 lists native synced audio for 3 to 10 seconds. Each is a prompt-to-clip request, not an interactive session.
| Row | Audio | Duration |
|---|---|---|
| minimax-h3 | native stereo, no toggle | 5–15 s |
| minimax-h3-max | native stereo, no toggle | 5–15 s |
| gemini-omni-flash-1.1 | native synced, no toggle | 3–10 s |
How do I check the live catalog?
Rows change, so query the catalog before you plan around one: GET /v1/video-router/models returns each row's capabilities, and GET /v1/video-router/models/{model_id} returns one row, or 404 for an unknown id. A 404 for a HelixWorld id is the expected answer today.
