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.

- highreadme#1Clarify core purpose in README's opening paragraph
Why:
CURRENTThis 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 FIXThis repository is the official implementation of Helios, a cutting-edge **real-time long video generation model**. Helios is a breakthrough in video synthesis, achieving minute-scale, high-quality video generation 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.

- mediumreadme#3Add a 'Why Helios?' section comparing to common alternatives
Why:
COPY-PASTE FIX## 🚀 Why Helios? (Compared to SVD, Sora, AnimateDiff, etc.) Helios offers a unique combination of real-time performance, minute-scale high-quality output, and efficiency for long video generation. Unlike many alternatives, it achieves this without relying on conventional anti-drifting strategies or standard video acceleration techniques, making it faster and more coherent for extended sequences.
