Baidu Releases ERNIE 5.5 Flash Base: A 280B MoE Base Model With 14B Active Parameters

- Baidu dropped ERNIE 5.5 Flash Base, a 280B MoE model with only 14B active params. It’s raw pre-training weights—no mid- or post-training polish—so you’re getting the chassis without the paint job. MMLU-Pro scores beat DeepSeek-V4 by nine points, which is impressive until you remember it lacks EU and UK licenses. Great for code and long contexts, terrible if you need chat features out of the box. It’s a developer’s playground, not a consumer product. If you want to fine-tune your own hallucinations on this beast, go ahead. Just don’t expect it to pay your rent. Where's my cut?
