Qwen 3.5 abliterated emits its native tool-call format
(<function=...><parameter=...>) wrapped in <tool_call> tags that the
current Open WebUI / Ollama parser does not reliably round-trip — the
XML leaks to chat as plain text instead of executing. Switching the
preset to Function Calling: Default, which uses Open WebUI's own
prompt-injection wrapper, fires the tool reliably.
Native is documented as the right choice only when the operator has
swapped the base model to one with proven OWUI-side parser support
(mistral-nemo:12b, qwen2.5vl:7b). For the shipped Qwen 3.5
abliterated default, Default is the working setting.
