Technical Details and Accessibility

Baidu has made the Ernie 4.5 models available under the Apache 2.0 license, allowing for both academic and commercial usage 5

5

. The company has also released ErnieKit, a development toolkit that enables developers to perform pre-training, supervised fine-tuning, and other customization techniques 5

.

The largest Ernie model features 424 billion parameters, while the MoE models have 47 billion parameters with three billion active at a time 5

5

. Baidu used advanced training methods, including heterogeneous MoE structure and techniques like intra-node expert parallelism and FP8 mixed-precision training 5
