Real-Time Long Video Generation (Fastest Variant)

Most AI video tools top out at short clips (5–10 seconds) or slow to a crawl for longer content — and they often need an expensive multi-GPU cluster to keep up. Helios-Distilled is the fastest, most efficient member of the Helios family: it turns text prompts, images, or existing videos into fluid, high-quality clips of up to ~45 seconds, generated in real time on a single GPU. Purpose-built for teams that need production-ready video at speed and scale. Built by PKU-YuanGroup.

What it does

Helios-Distilled is an AI video generation model that turns text prompts, images, or existing videos into fluid, high-quality video content. It is the fastest and most efficient version in the Helios model family, purpose-built for teams that need production-ready video output at speed and scale. Unlike most competing video AI tools that struggle with longer clips or require expensive multi-GPU infrastructure, Helios-Distilled generates up to 45 seconds of coherent, high-quality video in real time.

Problem it solves

• Long-form video at speed – Most AI video tools top out at short clips (5–10 seconds) or slow down dramatically for longer content. Helios-Distilled generates up to 45 seconds of video in real time
• Cost-effective infrastructure – Runs on a single GPU rather than expensive multi-GPU server clusters, significantly reducing compute costs
• Flexible creative input – Works from a text description alone, a starting image, or an existing video clip — fitting a wide range of creative and production workflows
• Temporal coherence – Videos remain visually consistent and coherent throughout their full length, without the common "drift" or degradation seen in longer AI-generated clips
• Production-ready deployment – Designed from the ground up to integrate into existing production pipelines and tools

Input/Output

• Input:

  • Text to Video: Describe the scene you want in plain language and Helios generates the video

    

  • Image to Video: Provide a starting image and a description of the motion or scene

  • Video to Video: Provide an existing video clip and a description to transform or extend it

• Output: A fully generated MP4 video file

  • Up to ~45 seconds in length

  • High visual quality with smooth, coherent motion throughout
