Baidu releases ERNIE 5.1 with compressed parameters and training cost

百度发布ERNIE 5.1模型，实现参数与成本的极致压缩

Baidu released ERNIE 5.1 with total parameters reduced to about one third of the original scale, active parameters to about one half, and pretraining cost to about 6% of same-scale models; the model is available on the ERNIE platform and Baidu AI Studio.

Why it matters: HKR-H/K/R all pass: Baidu ERNIE 5.1 is a domestic flagship-model release with concrete compression and 6% pretraining-cost claims. That puts it in the must-write band.
