ERNIE 5.5 Flash Base follow-up: weights license excludes South Korea and Europe from permitted regions (report)

Announced November 5, 2026

Verified (fact)

According to AI Times, the 'ERNIE 5.5 Flash Base' weights Baidu uploaded to Hugging Face on the 5th exclude South Korea and Europe from the list of regions where use is permitted. The model is a base model that has only completed pretraining, with an MoE architecture that activates only 14B of its 280B total parameters per token. Baidu said it scored higher than competing models from DeepSeek, Tencent, and Xiaomi in its own evaluations.

Needs fact-check (claim)

Baidu claims its own evaluations show higher performance on key benchmarks than competing models from DeepSeek, Tencent, and Xiaomi

Why it matters (interpretation)

Although the weights are public, Korean developers and companies are likely unable to use the model under the license. It shows that before adopting Chinese open-weight models, teams need to check even the regional clauses of the license.
