Baidu’s illustration of ERNIE Evolve, its automated AI research system.

Baidu unveiled ERNIE Evolve, an AI system that runs its own experiments to improve AI code. Baidu says it sped up its in-development ERNIE-5.5-Flash model by 33.7% on GPUs and more than sixfold on Kunlunxin chips. All figures are Baidu’s own.

Baidu has built an AI system that runs its own experiments to improve AI code, and says it has already sped up its next model, the company said on Monday . The system, ERNIE Evolve, picks what to research, edits code and runs tests. It keeps only changes that pass separate checks the AI cannot see.

Baidu used it on ERNIE-5.5-Flash, a model still in development. On P800 chips from Kunlunxin, the Baidu chip unit eyeing an IPO , it says the model now generates text more than six times faster. On GPUs already tuned by engineers, it raised throughput by 33.7% in about three days.

The Kunlunxin figure needs context.…
