Baidu launches ERNIE 5.1, slashes training cost
Baidu says ERNIE 5.1 inherits ERNIE 5.0’s foundation while shrinking total parameters to about one-third, active parameters to about one-half, and pre-training compute to roughly 6% of comparable models. It says the model improves agentic tasks, search, reasoning, and creative writing, with strong results on Arena Search.
The story here is efficiency as much as capability: Baidu is arguing that ERNIE 5.1 reaches near-frontier performance with dramatically lower training cost. The release highlights a claimed 6% pre-training cost versus comparable models, better agentic and reasoning performance, stronger world-knowledge and creative-writing results, and a 4th-place global, 1st-place Chinese showing on Arena Search.
