Problem Description

Filters that have been set to "global" started to behave weirdly after the reent 0.6.11 update. Non-global filters don't have this issue. The trigger seems to be the moment when front-end fetches the model list from the backend. This is how the problem can be reproduced:

Plugin Code

"""
title: Example Filter
author: open-webui
author_url: https://github.com/open-webui
funding_url: https://github.com/open-webui
version: 0.1
"""


class Filter:

    def __init__(self):
        print("GLOBAL FILTER __init__ CALLED.")

Maybe this function caused the problem, and the /api/models is very slow now.
