Baidu ERNIE 5.5 Flash Preview

Baidu released ERNIE 5.5 Flash Preview, a 280B-parameter mixture-of-experts model with 14B active parameters and a 1M-token context.

Baidu calls it an intermediate post-training checkpoint aimed at coding, 3D modeling, knowledge work and content creation, and warns some capabilities may lag until the final release. The API is live on Baidu's Qianfan platform; Baidu says the weights will be open-sourced under Apache 2.0 'soon', with no date.
