Star-Light-9698 · reddit · 2026-11-11
Google's Gemini model picker now uses functional names — Quick answers (3.5 Flash-Lite), All-around help (3.8 Flash), Detailed research (3.1 Pro), Most complex work (4 Carbon) and Code & analysis (4 Argon). The poster suspects 4 Carbon is an unannounced, cheaper swap-in model, and notes all modes now default to NB 2.1, with NB2, Pro and Lite no longer selectable.
