# OCR-based PDF loader This implements [Zerox](https://github.com/getomni-ai/zerox) PDF document loader. Zerox utilizes simple but very powerful (even though slower and more costly) approach to parsing PDF documents: it converts PDF to series of images and passes it to a vision model requesting the contents in markdown. It is especially suitable for complex PDFs that are not parsed well by other alternatives. ## Example use: ```python from langchain_community.document_loaders.pdf import ZeroxPDFLoader os.environ["OPENAI_API_KEY"] = "" ## your-api-key model = "gpt-4o-mini" ## openai model pdf_url = "https://assets.ctfassets.net/f1df9zr7wr1a/soP1fjvG1Wu66HJhu3FBS/034d6ca48edb119ae77dec5ce01a8612/OpenAI_Sacra_Teardown.pdf" loader = ZeroxPDFLoader(file_path=pdf_url, model=model) docs = loader.load() ``` The Zerox library supports wide range of provides/models. See Zerox documentation for details. - **Dependencies:** `zerox` - **Twitter handle:** @martintriska1 If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, ccurme, vbarda, hwchase17. --------- Co-authored-by: Erick Friis <erickfriis@gmail.com>
