This package use GeneralAgent lib to interact with OpenAI API.

1. 使用 PyMuPDF 库，对 PDF 进行解析出所有非文本区域，并做好标记，比如:

2. 使用视觉大模型（如 GPT-4o）进行解析，得到 markdown 文件。

See examples/attention_is_all_you_need/output.md for PDF examples/attention_is_all_you_need.pdf.

pip install gptpdf

from gptpdf import parse_pdf
api_key = 'Your OpenAI API Key'
content, image_paths = parse_pdf(pdf_path, api_key=api_key)
print(content)

See more in test/test.py

parse_pdf(pdf_path, output_dir='./', api_key=None, base_url=None, model='gpt-4o', verbose=False)

parse pdf file to markdown file, and return markdown content and all image paths.

• pdf_path: pdf file path

• output_dir: output directory. store all images and markdown file

• api_key: OpenAI API Key (optional). If not provided, Use OPENAI_API_KEY environment variable.

• base_url: OpenAI Base URL. (optional). If not provided, Use OPENAI_BASE_URL environment variable.

• model: OpenAI Vison LLM Model, default is 'gpt-4o'. You also can use qwen-vl-max

• verbose: verbose mode
