Model Card

The H2OVL-Mississippi-2B is a high-performing, general-purpose vision-language model developed by H2O.ai to handle a wide range of multimodal tasks. This model, with 2 billion parameters, excels in tasks such as image captioning, visual question answering (VQA), and document understanding, while maintaining efficiency for real-world applications.

The Mississippi-2B model builds on the strong foundations of our H2O-Danube language models, now extended to integrate vision and language tasks. It competes with larger models across various benchmarks, offering a versatile and scalable solution for document AI, OCR, and multimodal reasoning.

Key Features:

2 Billion Parameters: Balance between performance and efficiency, making it suitable for document processing, OCR, VQA, and more.
Optimized for Vision-Language Tasks: Achieves high performance across a wide range of applications, including document AI, OCR, and multimodal reasoning.
Comprehensive Dataset: Trained on 17M image-text pairs, ensuring broad coverage and strong task generalization.

Usage

Install dependencies:

pip install transformers torch torchvision einops timm peft sentencepiece

If you have ampere GPUs, install flash-attention to speed up inference:

pip install flash_attn

Sample demo:

import torch
from transformers import AutoModel, AutoTokenizer


# Set up the model and tokenizer
model_path = 'h2oai/h2ovl-mississippi-2b'
model = AutoModel.from_pretrained(
    model_path,
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True).eval().cuda()
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True, use_fast=False)
generation_config = dict(max_new_tokens=1024, do_sample=True)


# pure-text conversation
question = 'Hello, who are you?'
response, history = model.chat(tokenizer, None, question, generation_config, history=None, return_history=True)
print(f'User: {question}\nAssistant: {response}')


# Example for single image
image_file = './examples/image1.jpg'
question = '<image>\nPlease describe the image in detail.'
response, history = model.chat(tokenizer, image_file, question, generation_config, history=None, return_history=True)
print(f'User: {question}\nAssistant: {response}')


# Example for multiple images - multiround conversation
image_files = ['./examples/image1.jpg', './examples/image2.jpg']
question = 'Image-1: <image>\nImage-2: <image>\nDescribe the Image-1 and Image-2 in detail.'
response, history = model.chat(tokenizer, image_files, question, generation_config, history=None, return_history=True)
print(f'User: {question}\nAssistant: {response}')

question = 'What are the similarities and differences between these two images.'
response, history = model.chat(tokenizer, image_files, question, generation_config=generation_config, history=history, return_history=True)
print(f'User: {question}\nAssistant: {response}')
