Model details

Model type: LLaVA is an open-source chatbot trained by fine-tuning LLaMA/Vicuna on GPT-generated multimodal instruction-following data. It is an auto-regressive language model, based on the transformer architecture.

Model date: LLaVA-LLaMA-2-7B-Chat-LoRA-Preview was trained in July 2023.

Intended use

Primary intended uses: The primary use of LLaVA is research on large multimodal models and chatbots.

Primary intended users: The primary intended users of the model are researchers and hobbyists in computer vision, natural language processing, machine learning, and artificial intelligence.

Training dataset

• 558K filtered image-text pairs from LAION/CC/SBU, captioned by BLIP.
• 80K GPT-generated multimodal instruction-following data.

Evaluation dataset

A preliminary evaluation of the model quality is conducted by creating a set of 90 visual reasoning questions from 30 unique images randomly sampled from COCO val 2014 and each is associated with three types of questions: conversational, detailed description, and complex reasoning. We utilize GPT-4 to judge the model outputs. We also evaluate our model on the ScienceQA dataset. Our synergy with GPT-4 sets a new state-of-the-art on the dataset. See https://llava-vl.github.io/ for more details.

Usage

usage is as follows

from transformers import LlavaProcessor, LlavaForCausalLM
from PIL import Image
import requests
import torch

processor = LlavaProcessor.from_pretrained(PATH_TO_CONVERTED_WEIGHTS)

url = "https://llava-vl.github.io/static/images/view.jpg"
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
prompt = "How can you best describe this image?"

inputs = processor(text=prompt, images=image, return_tensors="pt").to("cuda",
