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

Pip Install

Open WebUI Version

0.8.5

Ollama Version (if applicable)

0.16.2

Operating System

Ubuntu 22.04

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

When a tool is enabled for a chat/model and the user asks a task that requires it, Open WebUI should invoke the tool and show the tool output.

Actual Behavior

After upgrading to v0.8.4/v0.8.5:

Tools are enabled in the chat/model, but they are never invoked.
The assistant responds without calling the tool (no tool execution occurs).
Downgrading back to v0.8.3 fixes the issue immediately.

Steps to Reproduce

Install and run Open WebUI v0.8.3 (pip + systemd), confirm tool calling works (e.g., a "ping" tool).
Upgrade to v0.8.4 or v0.8.5 via pip.
Restart service.
Open a chat, enable the tool, ask a prompt that should call the tool (e.g., “Call ping tool now”).
Observe: no tool invocation happens.

Logs & Screenshots

I’m attaching:

/api/version and /_app/version.json outputs
/api/v1/tools/ output (authenticated)
systemd service unit and environment (redacted)
nginx config (redacted) and nginx logs
Open WebUI journalctl logs with GLOBAL_LOG_LEVEL=DEBUG enabled
Browser console + network logs (HAR), if needed
Ollama version/list

Additional Information

v0.8.5 introduced “frontend initialization resilience” where getTools/getModels/etc can fail without blocking the page load. This might hide tool initialization failures in the UI. (If relevant, I can provide browser Network/Console logs.)
v0.8.4 also changed tools list loading/performance behavior.
