Baidu Wenxin released ERNIE 5.5 Flash Preview, open source weights before November 25

According to IT Home, Baidu's Wenxin large model has released ERNIE 5.5 Flash Preview, which is the first post-training version based on the previously released Base model. This model has a total of 280 billion parameters, with 14 billion active parameters, and supports 1 million contexts. The official claims it performs excellently in programming, 3D modeling, knowledge work, content creation, and more.

ERNIE 5.5 Flash Preview balances intelligence level and inference efficiency, achieving competitive scores in multiple benchmark tests while maintaining a fast decoding speed. The model API has been launched on the Qianfan platform, and the weights will be open-sourced before November 25.

Baidu stated that this model is an intermediate version in the post-training process. Although it has achieved competitive performance among models of the same size, there may still be some capability deficiencies due to insufficient training. Post-training is still ongoing and will be optimized in the subsequent official version.
