  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.6.2

Ollama Version (if applicable)

Operating System

Debian

Browser (if applicable)

Chrome

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have listed steps to reproduce the bug in detail.

Expected Behavior

I have encountered an issue with Mistral OCR's PDF parsing functionality when used within the knowledge base component. When processing the same PDF document:

  1. Mistral OCR in knowledge base: Produces incomplete extraction, significantly shorter than expected
  2. Tika with the same document: Successfully extracts the complete content
  3. Mistral Chat with the same document: Successfully parses the PDF without truncation issues

This suggests the issue may be specific to how Mistral OCR is implemented within the knowledge base integration.

Technical details:

Is there a known limitation in how Open WebUI implements the Mistral API for knowledge base document processing? Are there configuration parameters that need adjustment to enable complete document parsing?

Actual Behavior

Mistral OCR in knowledge base: Produces incomplete extraction, significantly shorter than expected

Steps to Reproduce

  1. Set Document, Content Extraction Engine to Mistral OCR
  2. Go to Workspace, Knowledge base, open any knowledge base
  3. Upload the pdf and check the parsed document
