On November 11, Baidu released ERNIE 5.5 Flash Preview, the first post-trained model built on its ERNIE 5.5 Flash Base. It has 280B total parameters with 14B active and a 1M-token context. Baidu pitches it for coding (including long-horizon tasks and game development in Unreal Engine, Unity, and Godot), 3D modeling, knowledge work, and content creation. Every showcased piece was completed inside an agent harness. The API is available now on Baidu's Qianfan platform. Baidu says the weights will be open-sourced under Apache 2.0 soon. Baidu calls it an intermediate checkpoint, and post-training is still ongoing before the official release. No pricing was stated on the announcement page. Source: Baidu ERNIE release page.
