Baidu launches ERNIE 5.5 Flash Preview: 280B MoE that CAD-designed a moon rover in code

Baidu has launched ERNIE 5.5 Flash Preview. The standout demo: the model wrote Python for FreeCAD to design a moon rover inspired by China's Yutu-2, which explored the lunar far side.
It's not a static 3D model — suspension arm movements reposition every wheel, and both solar panels rotate on their hinges. The whole model stays editable, so engineers can open and refine it, potentially jump-starting early mechanical design work.
Baidu also claims strengths in large coding tasks, game building, docs/slides generation, and video creation.
Specs: 280B parameters with 14B active per token, 1M-token context, and 200+ tokens per second via Baidu's Qianfan API.
