HOW TO READ THIS REPORT

Action plan is what to do next — copy-pasteable changes prioritized by impact. Category visibility is the real GEO test: when a user asks an AI a brand-free question that should surface PKU-YuanGroup/Helios, does the AI actually recommend you — or your competitors? Objective checks verify the metadata signals AI engines weight first. Self-mention check detects whether AI even knows you exist by name.

OVERALL DIRECTION
  • highreadme#1
    Clarify the README's opening statement to emphasize its research/developer focus and specific niche

    Why:

    CURRENT
    This repository is the official implementation of Helios, which is a breakthrough video generation model that achieves minute-scale, high-quality video synthesis at **19.5 FPS on a single H100 GPU** (about 10 FPS on a single Ascend NPU) —without relying on conventional long video anti-drifting strategies or standard video acceleration techniques.
    COPY-PASTE FIX
    This repository presents Helios, a breakthrough *research model* for real-time, minute-scale long video generation. Designed for AI researchers and machine learning engineers, Helios achieves high-quality video synthesis at **19.5 FPS on a single H100 GPU** (about 10 FPS on a single Ascend NPU) —without relying on conventional long video anti-drifting strategies or standard video acceleration techniques.
  • mediumcomparison#2
    Add a 'Comparison to Alternatives' section in the README

    Why:

    COPY-PASTE FIX
    ## 💡 Comparison to Alternatives

Unlike general video editing software (e.g., FFmpeg, OBS Studio) or game engines (e.g., Unreal Engine, Unity), Helios is a dedicated *generative AI model* focused on real-time, minute-scale video synthesis. Compared to consumer-oriented text-to-video platforms (e.g., RunwayML Gen-2, Pika Labs), Helios offers a research-grade, open-source implementation with unparalleled efficiency and quality for long video generation, specifically designed for developers and researchers seeking to push the boundaries of real-time generative video.
  • mediumabout#3
    Expand the repository's 'About' description

    Why:

    CURRENT
    Helios: Real Real-Time Long Video Generation Model
    COPY-PASTE FIX
    Helios is a cutting-edge research model for real-time, minute-scale long video generation, achieving high-quality synthesis without conventional anti-drifting or acceleration techniques. Ideal for AI researchers and ML engineers.
