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.

I found some existing issues that might be related. Please check if any of these are duplicates or contain helpful solutions:

  1. 🟣 #18998 feat: Support Openrouter image generation
    This is the original feature request for OpenRouter image generation support, directly matching the new issue’s topic. It provides context that OpenRouter image generation has been a known area of work in Open WebUI.

  2. 🟣 #20634 issue: OpenRouter image generation Chunk too big error
    This issue reports a failure specifically when generating images through OpenRouter, which is very close to the new report. The symptom differs (Chunk too big vs a generic generation error), but both are OpenRouter image-generation breakages.
    by eniraa · bug

  3. 🟣 #23611 bug: Image generation fails with providers that don't support 'size' parameter (e.g., xAI/grok-imagine-image)
    This bug is about image generation failing because Open WebUI sends unsupported parameters to the upstream provider. The new issue also involves OpenRouter image generation failing, so this is relevant as a likely similar integration/parameter-handling problem.
