Baidu ERNIE 5.5 Flash Preview Released: 11 Hours of C++ Work Produce a Wuxia Game

Dongcha Beating AI News Flash: Baidu has released ERNIE ERNIE 5.5 Flash Preview. This is the first post-training version of 5.5 Flash Base, open-sourced last week, with a focus on improving coding,Agent and complex task execution. The model has a total of 280000000000, with 14000000000 parameters activated per run, and supports a 1000000 Token context.

Baidu showcased a 3D wuxia game, Yunxiu Xing, developed by the model. In a task lasting 11 hours, the model used C++ to develop a game in Unreal Engine 5.8 and also integrated assets from different engine versions.

Notably, ERNIE 5.5 Flash is a text-only model and cannot see the game visuals. It turned issues found in playtest feedback, such as characters floating in the air, movement in the wrong direction, and misaligned camera angles, into executable code tests, then repeatedly made changes based on the test results. The environments and characters used off-the-shelf asset packs.

Baidu also conducted specialized training for professional software such as Blender and CAD. In the official demo, two Agent worked separately on an airport and an airplane, then unified the scene and camera and rendered an animation. The model also used Python scripts to create editable W16 engines and lunar rovers in FreeCAD, and can call external tools such as Seedance to make videos.

In the evaluations published by the company,Terminal-Bench 4.0 scored 46.5 points, ahead of the domestic models it was compared with, including Hy4、DeepSeek V4.1 Flash, but still behind leading models such as Claude Opus 5.5.API is now available on Qianfan. During the limited-time off period, per million Token tokens, peak-hour input costs about 1 yuan and output 4 yuan; off-peak prices are 0.5 yuan and 2 yuan, respectively.

Baidu also pledged to release Preview weights later under the Apache 2.0 License.
