h2ovl-mississippi-800m

Model Card

The H2OVL-Mississippi-800M is a compact yet powerful vision-language model from H2O.ai, featuring 0.8 billion parameters. Despite its small size, it delivers state-of-the-art performance in text recognition, excelling in the Text Recognition segment of OCRBench and outperforming much larger models in this domain. Built upon the robust architecture of our H2O-Danube language models, the Mississippi-800M extends their capabilities by seamlessly integrating vision and language tasks.

Key Features:

• 0.8 Billion Parameters: Balance between performance and efficiency, making it suitable for OCR and document processing.
• Trained on 19 million image-text pairs, with a focus on OCR, document comprehension, and chart, figure, and table interpretation, the model is optimized for superior OCR performance.

Usage

Install dependencies:

pip install transformers torch torchvision einops timm peft sentencepiece flash_attn

Sample demo:

import torch
from transformers import AutoConfig, AutoModel, AutoTokenizer


# Set up the model and tokenizer
model_path = 'h2oai/h2ovl-mississippi-800m'
config = AutoConfig.from_pretrained(model_path, trust_remote_code=True)
config.llm_config._attn_implementation = 'flash_attention_2'
model = AutoModel.from_pretrained(
    model_path,
    torch_dtype=torch.bfloat16,
    config=config,
    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=2048, do_sample=True)

# pure-text conversation
question = 'Hello, how 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/image.jpg'
question = '<image>\nRead the text in the image.'
response, history = model.chat(tokenizer, image_file, question, generation_config, history=None, return_history=True)
print(f'User: {question}\nAssistant: {response}')
