# OpenWebUI Filter that collapses model reasoning/thinking into a
# separate section in the reply. This is specificially for the
# Artificium model, based on Llama 3.1. It outputs its thought
# processes broken by markdown horizontal rules. Usually, it outputs a
# basic thought process followed by a breakdown. GENERALLY, text below
# the last horizontal line is the final answer.
#
# Based on the Add or Delete Text Filter by anfi.
