New default model and effort
- Sonnet 5.5 is now the default model.
- GPT-6.1 Sol and GPT-6 Luna replace GPT-5.6 Sol and Luna in the model picker.
- The effort setting now defaults to Medium. It’s also now an inline Low / Medium / High row in the model menu, not a submenu, so it fits in the PowerPoint add-in.
Fixes
- A thinking block you’ve opened stays open while the response streams.
- Fixed requests that could fail straight after signing in.
