parsing_auto()

Automatically select an appropriate parser based on detected file types

Automatically select an appropriate parser based on detected file types. Documents with unrecognizable formats won’t be processed and will generate an error in the ai.vectorizer_errors table.

Parser selection

The parser selection examines file extensions and content types:

• PDF files, images, Office documents (DOCX, XLSX, etc.): Uses Docling
• EPUB and MOBI (e-book formats): Uses PyMuPDF
• Text formats (TXT, MD, etc.): No parser used (content read directly)

Samples

Use automatic parser selection

SELECT ai.create_vectorizer(
    'documents'::regclass,
    loading => ai.loading_uri('file_path'),
    parsing => ai.parsing_auto(),
    embedding => ai.embedding_openai('text-embedding-3-small', 768)
);

Arguments

This function takes no parameters.

Returns

A JSON configuration object for use in create_vectorizer().
