  • I have searched for any existing and/or related discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.30

Ollama Version (if applicable)

0.12.2

Operating System

Fedora 42

Browser (if applicable)

No response

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 provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Open WebUI is able to use newer SentenceTransformer embedding models (e.g. EmbeddingGemma, KaLM etc..)

Actual Behavior

Open WebUI seems to be stuck to ST 4.1.0 which is almost 6 months old.

Steps to Reproduce

  1. install latest OI Docker version
  2. Admin settings → Settings → Documents → Embedding Model: set to any newer model (e.g. unsloth/embeddinggemma)
  3. gets the following in the log:

You are trying to use a model that was created with Sentence Transformers version 5.1.0, but you are using version 4.1.0. This might cause unexpected behavior or errors. In that case, try to update to the latest version.

  1. And no embedding works anymore (knowledge/documents etc..)

Logs & Screenshots

_load_sbert_model: 1695 - You are trying to use a model that was created with Sentence Transformers version 5.1.0, but you are using version 4.1.0. This might cause unexpected behavior or errors. In that case, try to update to the latest version.
