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

Pip Install

Open WebUI Version

0.8.12

Ollama Version (if applicable)

No response

Operating System

Ubuntu

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

I am using models capable of multi-step reasoning and tool use (Qwen 3.5 models). My workflow involves multiple tool calls sequentially within a single turn.

When the LLM executes a sequence of tools (e.g., Tool 1 → Tool 2 → Tool n), Tool n requires the data returned by Tool 1 or Tool 2 (history of the outputs). However, when inspecting the __messages__ or __metadata__ or __tools__ arguments inside Tool n, the results/outputs of the previous tools are missing.

As far as I remember, it was possible few months ago with a previous version (or maybe im missing something).
The full history of tool calls/outputs should be available.

Actual Behavior

The full history of tool calls/outputs is not available.

Steps to Reproduce

  1. Create two tools: Tool_A (returns a string "Data from A") and Tool_B (prints the content of __messages__).
  2. Use a model (Qwen 3.5) for tool chaining
  3. Observe the reserved arguments of Tool_B.

Logs & Screenshots

None
