Model Details

Japanese Stable VLM is a vision-language instruction-following model that enables to generate Japanese descriptions for input images and optionally input texts such as questions.

Usage

from PIL import Image
import requests

# helper function to format input prompts

Model Details

Training

This model is a vision-language instruction-following model with the LLaVA 1.5 architecture. It uses stabilityai/japanese-stablelm-instruct-gamma-7b as a language model and openai/clip-vit-large-patch14 as an image encoder. During training, the MLP projection was trained from scratch at the first stage and the language model and the MLP projection were further trained at the second stage.

Training Dataset

The training dataset includes the following public datasets:

Use and Limitations

Intended Use

This model is intended to be used by the open-source community in vision-language applications.

Limitations and bias

The training dataset may have contained offensive or inappropriate content even though we applied data filters. We recommend users exercise reasonable caution when using these models in production systems. Do not use the model for any applications that may cause harm or distress to individuals or groups.
