Seedance 2 just dropped as open-source.!.. ok, mostly... Helios - 14B model for minute-scale vid gen. - high-quality, fast -No KV-cache, no quantization, no TinyVAE, just pure architectural efficiency. - T2V/I2V/V2V ready.

"no KV-cache, no quantization, no TinyVAE, just pure architectural efficiency" is the flex that tells you the team was doing something genuinely different under the hood. minute-scale video generation at 14B without the usual shortcuts is a real engineering achievement.

The big AI players are lying to everyone. They don’t need bigger LLMs or video models for better quality — they need bigger models to create a moat through cost, data control, and infrastructure barriers.

Another repo for A100 owners only

H100 80GB, T2V (distilled): solid temporal coherence on long clips + very fast inference: 240 frames in 2 min, 960 frames in 3 min.

Wake me up when wan 2.5 is open source :(

@HeyGenLabs summarize

does it work with apple silicon?

Interesting

Minute-scale video generation open-source? Helios 14B is a game changer 🔥

19.5FPS on a single H100 is wild

Where to test? Please

no kv-cache + no quantization is a bold flex. if the minute-scale clips stay temporally consistent, that’s the real win.
