📄 Description

Changelog Entry

Description

These are very minimal changes to test docling for experimental purposes, not ready to be released yet. The goal is just to highlight what could be done for integrating docling for contributors who would have time for further testing and implementation. I will not have enough time in the coming days or weeks to build further, please do feel free to build upon this.

Approach 1 : using langchain_docling as in the first commit of this PR. I made it work but it used the CPU and not the GPU, leading to unreasonable processing times (a few minutes) for hundreds of pages PDFs. Proposed improvements:
- find how to use GPU when available
- warn for processing times for long documents in case of CPU only and/or fallback to default engine
- handle full offline mode by integrating models into the library, see https://github.com/DS4SD/docling/issues/326
Approach 2 : using docker image as Docling team has been recently active in docling-serve (see https://github.com/DS4SD/docling-serve/pkgs/container/docling-serve) and we can probably expect soon a docling docker image as for Apache Tika. Then Ctrl+F of Tika usage in Open WebUI repo and replicate the logic for Docling. Here also to pay attention to CPU/GPU considerations.

Both approaches could possibly be implemented so that the user can choose between both options depending on their needs.
