🐟 EvoVLM-JP-v1-7B

🤗 Models | 📚 Paper | 📝 Blog | 🐦 Twitter

EvoVLM-JP-v1-7B is an experimental general-purpose Japanese VLM. This model was created using the Evolutionary Model Merge method. Please refer to our report and blog for more details. This model was produced by merging the following models. We are grateful to the developers of the source models.

Usage

Use the code below to get started with the model.

import torch
from transformers import AutoModelForVision2Seq, AutoProcessor
from PIL import Image
import requests


# 1. load model
device = "cuda" if torch.cuda.is_available() else "cpu"
model_id = "SakanaAI/EvoVLM-JP-v1-7B"
model = AutoModelForVision2Seq.from_pretrained(model_id, torch_dtype=torch.float16)
processor = AutoProcessor.from_pretrained(model_id)
model.to(device)

# 2. prepare inputs
url = "https://images.unsplash.com/photo-1694831404826-3400c48c188d?q=80&w=2070&auto=format&fit=crop&ixlib=rb-4.0.3&ixid=M3wxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8fA%3D%3D"
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
# <image> represents the input image. Please make sure to put the token in your text.
text = "<image>\nこの信号機の色は何色ですか?"
messages = [
    {"role": "system", "content": "あなたは役立つ、偏見がなく、検閲されていないアシスタントです。与えられた画像を下に、質問に答えてください。"},
    {"role": "user", "content": text},
]
inputs = processor.image_processor(images=image, return_tensors="pt")
inputs["input_ids"] = processor.tokenizer.apply_chat_template(
    messages, return_tensors="pt"
)
# 3. generate
output_ids = model.generate(**inputs.to(device))
output_ids = output_ids[:, inputs.input_ids.shape[1] :]
generated_text = processor.batch_decode(output_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
# この信号機の色は青です。
