Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.8.8

Ollama Version (if applicable)

No response

Operating System

Ubuntu 24.04

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

Create a new chat. Ask "What is your favorite color?". Get a response, e.g. "Blue". Edit the response to say something else, e.g. "Yellow". Ask "What color did you name just now?". Correct response "Yellow".

Actual Behavior

Create a new chat. Ask "What is your favorite color?". Get a response, e.g. "Blue". Edit the response to say something else, e.g. "Yellow". Ask "What color did you name just now?". Wrong response "Blue".

Steps to Reproduce

  1. Create a new chat
  2. Ask a question
  3. Edit the answer to something different
  4. Ask something else, referring to the modified answer

Result: Get a response referring the original answer before it was edited.

Additional Information

I was upgrading directly from 6.x to 0.8.5, when I first noticed the bug. Updated and checked every version since then, and the bug is consistent. I even set up a completely fresh v0.8.8 instance to verify this.

From the logs, it's clear that it's not an issue with the inferencing provider. Open-webui actually sends the wrong (i.e. unedited) chat history. I edited the LLM response from "Cerulean." to "Yellow."
