Baidu has released ERNIE 5.5 Flash Preview, which it describes as the first post-trained model built on ERNIE 5.5 Flash Base. The company says the model has 280 billion total parameters with 14 billion active and a 1 million-token context, and is aimed at coding, 3D modeling, knowledge work, and content creation. The API is available on Baidu's Qianfan platform, and Baidu says the weights will be open-sourced under Apache 2.0 soon. It also notes that this is an intermediate checkpoint and that post-training is still ongoing.
