Similar behaviour for me
@tjbck commented on GitHub (Oct 8, 2025):
@Geelhem how long is your model id?
@silentoplayz commented on GitHub (Oct 10, 2025):
I'm not sure if we want to close this issue out yet, so I'll just use this opportunity to link a related fix commit merged on the
devbranch for reference -5043e7fc8c.I will note that the linked commit only fixes the issue of being able to create models with a very long model name and model ID. Though, still, I am unable to edit, hide/show, delete, or toggle the custom workspace model with an excessively long name/ID.
@Geelhem commented on GitHub (Oct 10, 2025):
My issue was that the button to edit the models had disappeared for all models and when I was clicking on the model, I was not able to edit any model, and the screen would remain blank on the workspace tab. I have reverted to the 3.30 open Web UI version and this has solved the issue for me.

@Geelhem Within the workspace
Modelssection, the edit pencil icons are indeed gone, but clicking on the model should open up to the model's edit page. If this isn't happening for you on the latest version of Open WebUI and you believe there is a bug, try to reproduce it, check the browser console logs for any errors, and feel free to open up a fresh issue post of your own!@Geelhem commented on GitHub (Oct 12, 2025):
Clicking on the model opened the model’s chat, and there were no alternatives to edit the model

@Geelhem The way this is worded makes either of these issues seem like they may be related - https://github.com/open-webui/open-webui/issues/18127 & https://github.com/open-webui/open-webui/discussions/18135
@Geelhem commented on GitHub (Oct 13, 2025):
