πΉ True Single-GPU Extreme Speed β‘οΈ No need to rely on traditional workarounds like KV-cache, quantization, sparse/linear attention, or TinyVAE. Helios hits an end-to-end 19.5 FPS on a single H100!
Training is also highly accessible: an 80GB VRAM can fit four 14B models.
πΉ Solving Long-Video "Drift" from the Core π₯ Tired of visual drift and repetitive loops? We ditched traditional hacks (like error banks, self-forcing, or keyframe sampling).
Instead, our innovative training strategy simulates & eliminates drift directly, keeping minute-long videos incredibly coherent with stunning quality. β¨
πΉ 3 Model Variants for Full Coverage π οΈ With a unified architecture natively supporting T2V, I2V, and V2V, we are open-sourcing 3 flavors:
1οΈβ£ Base: Single-stage denoising for extreme high-fidelity. 2οΈβ£ Mid: Pyramid denoising + CFG-Zero for the perfect balance of quality & throughput. 3οΈβ£ Distilled: Adversarial Distillation (DMD) for ultra-fast, few-step generation.
πΉ Day-0 Ecosystem Ready π We wanted deployment to be a breeze from the second we launched. Helios drops with comprehensive Day-0 hardware and framework support:
