My motivation was to use the smartest model available (overall, not only from Google) - I wanted to squeeze more out of Gemini 3 Pro that in Cursor. With new model releases usually there are things with outages. This are ever changing.
That said, for many tasks (summaries and data extraction) I do use Gemini 2.5 Flash, as it cheap and fast. So excited to try Gemini 3 Flash as well.
