Nunchux AI 发布 VC-Attention 以加速视频扩散 Transformer

Nunchux AI 开发了 VC-Attention,这是一种新颖的、无需训练的低比特注意力核,旨在加速视频扩散 Transformer。这项创新解决了两个关键瓶颈:值量化误差和缓慢的 softmax 计算。通过实施 V-Smooth 等技术来管理值异常值,以及使用 ExpCast-FP8 进行高效的对数域指数运算,VC-Attention 显著加速了视频生成模型中的注意力机制。 AI

影响 该核可以显著减少视频生成模型的训练和推理时间,从而可能降低计算成本并提高可访问性。

    Nunchux AI 推出 VC-Attention:一种无需训练的低比特注意力核,可加速视频扩散 Transformer

    <p>Nunchux AI has released VC-Attention, a training-free low-bit attention kernel built for video Diffusion Transformers (DiTs). It targets 2 problems at once: value quantization error and a slow softmax stage. Why Attention is the Video Bottleneck Video DiTs flatten a clip into …
