201.1 Work IQ vs Auto: two different switches
Work IQ decides whose world Copilot reads: on uses your mail, files, chats, and meetings; off uses the web and what you attach. The model menu decides how hard it thinks: Auto picks a model for each request, or you choose a deeper option for hard work.

- Auto, Quick response, Think deeper.
- GPT or Claude.
- Work IQ.

- Open the model menu.
- More.
- Highlighted model.
Do this today: On one hard task, set Work IQ on purpose, then run it once on Auto and once on a deeper option. Keep the better one and note why.
