Product Positioning & Context

AI Executive Synthesis
A 'Real Real-Time Long Video Generation Model.'
This issue is a direct request for Helios's training data to be made publicly available. This reflects a common developer need for transparency and reproducibility in AI model development. Access to training data is crucial for researchers to understand model biases, replicate results, and potentially fine-tune models for specific use cases. For B2B SaaS, while proprietary training data can be a competitive advantage, making subsets or anonymized versions available can foster community engagement, accelerate research, and build trust. The decision to share or withhold training data has significant implications for ecosystem development and the broader adoption of the model in academic and commercial settings.

> is_amplify_history: false restrict_self_attn: false 大佬,现在的配置文件中这两个参数默认配置都是false,想请教下现在的base权重使用这两个训练策略了吗?

感谢关注!消融实验的时候用了

> 主要都是模拟推理过程吧。不加噪意味着完全干净的内容,但是模型推理出来的结果或多或少会和真实世界完全干净的内容有所差异

参考图x0 在推理过程中经过vae编码后就固定重复使用了,是一个干净的内容。反而训练的时候加噪了会和推理不一致吧?

@hyc9 Thanks for your interest! Regardless of the length of the generated video, the lengths of Helios' history context and noisy context are fixed, and the total number of tokens input to DiT is less than that of Wan, thus making it much faster.

@SHYuanBest 您好,我重启了一次stage1_init训练,8卡,batchsize=2, i2v的训练任务,把random_drop_t2v_ratio和random_drop_v2v_ratio都设置为了0。样本量比较少,一开始训练了3000step,视频的sections之间的闪烁在减弱,但是后面训练到了7000step,场景变化反而更大了,画面也开始变糊,请问这种现象是正常的吗?还是我应该直接继续做post训练呢?
下面是在3000和7000分别推理的视频

@ChirsHuanhuan Thank you for your interest! Due to policy restrictions, we cannot open-source the data. Please refer to https://github.com/PKU-YuanGroup/Helios/issues/35 and https://github.com/PKU-YuanGroup/Helios/issues/23 for more details.

1. "现在训练数据采样每次不都是从一段视频中采样连续的帧,一部分作为history 一部分作为待生成的,这样的话长视频和100多帧不是一样的吗":是的
2. “为啥长视频效果会更好呢~”:主要是为了让first frame anchor以"矫正drifting"的功能出现,而不是以"让模型copy首帧的内容"的功能出现。否则如果用短视频,就会出现和longlive、rollingforcing类似的那种运动静止的缺陷

> 我们的视频数据大多是几百帧的clips;可以的,个人感觉是长视频效果更佳。

@zkailinzhang 可以的,batchsize可以通过梯度累计调大
hotfinda • Mar 31, 2026
好的好的,感谢~我试一下

bs有点小,可以试着把`random_drop_t2v_ratio`关小,不然模型没学多少v2v任务
hotfinda • Mar 31, 2026
您好,我训练了8000step, batchsize1,lr固定5e-5
Yangxiaoda1 • Mar 31, 2026
如果训练数据是长度是1分钟的视频或者更长可以吗
SHYuanBest • Mar 31, 2026
排除代码/权重加载问题前提下,训练一开始是这样的,往后训会逐渐连贯。你这个大概训了多久?batchsize和lr分别是多少?
