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

0.6.33

Ollama Version (if applicable)

No response

Operating System

Debian 12

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

Clicking the "Continue" button should result in the model continuing its previous response, not starting the answer from the beginning.

Actual Behavior

The "Continue response" button in OpenWebUI does not behave as expected when using a custom model with a knowledge base (i.e., when RAG search is performed before answering). When I click "Continue," instead of continuing the previous response, it restarts the answer from the beginning, as if responding for the first time. This issue only occurs when a RAG search is involved. If I use a model without an attached knowledge base (no RAG query), the "Continue" button works correctly and continues the previous answer.

Steps to Reproduce

Attach a knowledge base to a custom model in OpenWebUI.
Ask a question so that a RAG search is triggered before the model answers.
After receiving the initial LLM response, click the "Continue" response button.
Observe that the response restarts from the root instead of continuing.

Logs & Screenshots

In this test, i wanted to continue the code generation because it has stopped. When i clicked on continue response, instead of continuing were it left off it started generating the code block again (line 137).

Model dependent behaviour.
