tool_choice: required (the thing that makes Image Studio reliably fire
its tools) also blocks Open WebUI's background text-only calls — title
generation, tag suggestions, autocomplete — because the model is
forced to produce a tool call instead of text. Result: chats stay
named 'New Chat' and tag suggestions go silent.
Documented the fix in two places:
- image_studio.md: dedicated 'Set a separate Task Model (required
after install)' section explaining the cause and the fix path.
- deployment README §9: short follow-up note pointing at it so
operators don't miss it during initial setup.
The fix is purely Open WebUI configuration — no code change. Pick any
non-Image-Studio model already pulled (mistral-nemo:12b is the
obvious default) for the Task Model slot.
