Zyphra 把 EEG 模型输入从固定5秒扩展到0.5-30秒,还开源了 Apache 2.0,搞脑电研究的可以直接上手。
Zyphra 于 2026 年 7 月 16 日发布 ZUNA1.1,采用 Apache 2.0 许可。该 380M 参数 masked diffusion autoencoder 能处理 0.5 至 30 秒的可变长度脑电图输入,而上一代 ZUNA1 仅支持固定 5 秒。模型支持任意通道布局下的重构、去噪和上采样,NMSE 指标保持不变或有所改善。
Zyphra Releases ZUNA1.1: An Apache 2.0 EEG Foundation Model With Variable-Length Inputs From 0.5 To 30 Seconds
Zyphra released ZUNA1.1 on July 16, 2026, under the Apache 2.0 license. The 380M masked diffusion autoencoder reconstructs, denoises, and upsamples scalp-EEG across arbitrary channel layouts. It accepts variable-length inputs from 0.5 to 30 seconds, against ZUNA1's fixed five seconds. Reported NMSE holds or improves while the input range widens.
