Bug Report

Installation Method

Conda environment with Open WebUI (main branch, v0.4.8).
Issue is reproducible in Docker as well.

Environment

  • Open WebUI Version: v0.4.8 (main branch, 2024-12-07)
  • Operating System: macOS 15.2
  • Browser (if applicable): Chrome 120.0

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on the latest version of Open WebUI.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

The application should remain responsive while processing a request to the /completions endpoint with ENABLE_RAG_HYBRID_SEARCH enabled.

Actual Behavior:

The application freezes during the execution of the /completions endpoint when ENABLE_RAG_HYBRID_SEARCH is enabled.

  • The UI becomes unresponsive and no further interactions can be made.
  • Once the /completions request completes, the app becomes functional again.

Description

Bug Summary:
When ENABLE_RAG_HYBRID_SEARCH is turned on and the reranking model BAAI/bge-reranker-v2-m3 is used, calling the /completions endpoint causes the application to freeze until the request finishes processing. This issue is consistent and reproducible.

Reproduction Details

Steps to Reproduce:

  1. Install Open WebUI using Conda or Docker.
  2. Enable ENABLE_RAG_HYBRID_SEARCH in the settings.
  3. Set the reranking model to BAAI/bge-reranker-v2-m3.
  4. Trigger a request to the /completions endpoint (e.g., perform a query using HybridSearch).
  5. Observe that:
    • The application freezes during the request execution.
    • No interactions can be performed until the /completions endpoint finishes processing.
  6. After the request completes, the app returns to normal.

Logs and Screenshots

Browser Console Logs:
N/A (no relevant logs).

Docker Container Logs:
N/A (no relevant logs).

Screenshots/Screen Recordings (if applicable):
N/A

Additional Information

  • The issue consistently occurs during /completions calls with HybridSearch enabled.
  • The reranking model in use is BAAI/bge-reranker-v2-m3.
  • CPU or memory usage appears normal during the freeze.
  • This behavior happens both in Conda and Docker installations.

Note

Please let me know if further testing or logs are required to resolve this issue. Thank you for maintaining Open WebUI!

What Embedding Model did you set? For information, I use the BAAI/bge-reranker-v2-m3 in hybrid search without problems. It just takes a while to get the answer, but CPU work is high at the time and the UI is responsive. (I also have top-k at 15)

I use BAAI/bge-reranker-v2-m3, also.
