ERNIE 4.5 VL 424B A47B combines image understanding with a heterogeneous mixture-of-experts architecture. The open model accepts text and images, activates 47 of 424 billion parameters, and uses 54 layers with a 131,072-token context.

Baidu documents thinking and non-thinking modes for its vision-language post-training. Apache 2.0 applies to the published weights. The exact profile identifier ends in PT. In the model card, PT denotes the PyTorch format, not a pretraining or base model. That distinction keeps the suffix from being mistaken for a different model variant.
