Description

Summary:

• This new feature introduces a comprehensive guide for processing multiple file formats using the Grok API. The notebook demonstrates how to extract, analyze, and compare information from PDFs, Word documents, and text files. It includes functionalities such as text extraction, summarization, Q&A, structured data extraction, metadata analysis, and file comparison.

Why this change matters:

• Grok AI currently lacks a dedicated file or PDF ingestion example. This addition enables users to process PDFs and other files seamlessly for RAG/Grok pipelines, filling a gap in the cookbook and improving usability for real-world document workflows.

Hi @avixai @Omar-V2

I've updated the PR to include a proper Summary and Description for better context on the changes. The new content clearly explains the file/PDF processing notebook and why it matters.

Please review the update at your convenience — it’s ready to merge if everything looks good. Thanks for your time!
