What changed

Baidu says ERNIE 5.5 Flash Preview is its first post-trained model built on the earlier ERNIE 5.5 Flash Base. It adds post-training for coding, game development, 3D modeling, knowledge work, and content creation while retaining a 1M-token context. Baidu says the model is still in preview.

Access and availability

Use the model through the Qianfan platform API. Baidu says API access is available now; model weights are planned for an Apache 2.0 release but were not yet available in the announcement.

What you can build

Treat this as a preview and verify outputs on your own coding or 3D workflow before relying on it for production work.

Limitations

This is explicitly a preview release, and the announcement says the weights will be open-sourced later, so local weight access was not available as of the announcement. Baidu's capability and benchmark claims are provider-reported.
