 # Model architecture
-The model was trained  a ViT-B/16 Transformer architecture as an image encoder and uses a 12-layer RoBERTa as a text encoder. The text encoder was trained upon the pre-trained Japanese RoBERTa model [rinna/japanese-roberta-base](https://huggingface.co/rinna/japanese-roberta-base) with the same sentencepiece tokenizer.
