from megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.parser.unstructured_parser import UnstructuredParser

parser = UnstructuredParser()
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md")

Use MegaParse Vision

Change the parser to MegaParseVision

from megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.parser.megaparse_vision import MegaParseVision

model = ChatOpenAI(model="gpt-4o", api_key=os.getenv("OPENAI_API_KEY"))  # type: ignore
parser = MegaParseVision(model=model)
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md")

Note: The model supported by MegaParse Vision are the multimodal ones such as claude 3.5, claude 4, gpt-4o and gpt-4.

(Optional) Use LlamaParse for Improved Results

1. Create an account on Llama Cloud and get your API key.
2. Change the parser to LlamaParser

from megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.parser.llama_parser import LlamaParser

parser = LlamaParser(api_key = os.getenv("LLAMA_CLOUD_API_KEY"))
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md") #saves the last processed doc in md format

Use as an API

There is a MakeFile for you, simply use make dev at the root of the project and you are good to go.
