Baidu announced ERNIE 5.5 Flash Preview on November 11, opening Qianfan API access to a model with 280 billion total parameters, 14 billion active per token and a one-million-token context window. The official announcement describes its focus on coding and tool-driven work.
Creative workflows, with tools doing their part
The interesting part is the workflow. Baidu showcases game development, Blender and CAD scripting, and video production inside an agent harness—the system that lets a model use tools and iterate. One demonstration describes an 11-hour Unreal Engine coding task. These examples use external assets and specialist tools; they are company demonstrations, not independent proof of production reliability. The underlying model is text-only, not a native video generator.
API access now; weights planned
OpenRouter currently lists a free, rate-limited endpoint. Downloadable weights are a separate milestone: Baidu promises Apache 2.0 licensing, and its Chinese announcement targets release before November 25. That is a planned release, not confirmation that the Preview weights are already publicly downloadable.
Baidu describes this as an intermediate checkpoint, with post-training still underway. Access to the preview should not be confused with a finished production model.
Why it matters
For small teams such as SunMarc App Labs, this is a candidate for bounded game-development experiments. The useful test is whether an agent can implement a mechanic, run checks and fix failures with less supervision—not simply produce an impressive demo. We have not tested the preview.
