上述论文有12篇被机器学习三大顶会接收: ICML、ICLR、NeurIPS,当然这些论文成果不仅停留在paper上，很多成果已被OpenAI ，Apple，stability.ai采用
Vidu核心技术建立在以上顶级基础研究之上
其核心技术U-ViT架构由团队于2022年9月提出，早于Sora采用的DiT架构，是全球首个个Diffusion与Transformer融合的架构
Vidu核心团队成员来自清华大学人工智能研究院，此外汇集了来自阿里、腾讯、字节等知名科技公司的顶尖人才
自从ChatGPT推出以后，OpenAI成为了全球人工智能发展的风向标，GPT3.5，GPT4，sora 三个里程碑影响了无数初创公司，OpenAI也变成了最神秘的人工智能公司，一举一动都受到各方关注，现在vidu的出现刷屏国内外各大媒体平台，一举打破了OpenAI神秘性
