# LLaVA-JP Model Card
## Model detail
**Model type:**
LLaVA-JP is a vision-language model that can converse about input images.<br>
This model was trained by fine-tuning [llm-jp/llm-jp-1.3b-v1.0](https://huggingface.co/llm-jp/llm-jp-1.3b-v1.0) using [LLaVA](https://llava-vl.github.io/) method.
**Training:**
This model was initially trained with the Vision Projector using [LLaVA-CC3M-Pretrain-595K-JA](https://huggingface.co/datasets/toshi456/LLaVA-CC3M-Pretrain-595K-JA) and STAIR Captions. <br>
In the second phase, it was fine-tuned with LLaVA-Instruct-150K-JA and Japanese Visual Genome.
