ERNIE 4.5
ERNIE 4.5 is Baidu’s Apache-licensed family of language and vision-language models. This page groups its dense and sparse text checkpoints with separately labeled multimodal variants. The largest vision-language checkpoint uses 424B total parameters and 47B active parameters, with 128K context. Heterogeneous expert routing supports cross-modal learning, while smaller models offer lower serving costs. The June 30 weight release follows earlier hosted availability; checkpoint-specific modality and size differences must be preserved.
