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

Version v0.8.10 (latest)

Ollama Version (if applicable)

No response

Operating System

Ubutu 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

Using AIML as model provider. When I use Claude 4.6 I expect for it to give me a full reply and not to be cut off.

Actual Behavior

Answers break from Claude opus 4.5, 4.6 most of anthropic api. Model provider AIML

Steps to Reproduce

  1. Configure AIML as model provider using their web base url : https://api.aimlapi.com/v1
  2. open a chat
  3. type in to generate code
  4. breaks around lines 40-45

Logs & Screenshots

do you use a reverse proxy between yourself and open webui? if so check your timeouts and check your open webui timeout env vars as well. Cannot reproduce with vertex ai, anthropic, openrouter, litellm and azure.

https://docs.openwebui.com/reference/env-configuration#aiohttp_client_timeout

https://docs.openwebui.com/reference/https/nginx

if you did all of this, likely provider issue

Hi! I wanted to update, the problem was the provider. Switched from AIML to OpenRouter.
