Promises with a season attached are watchlist items. The trackers hold the follow-through.
Information agents reached AI Ultra subscribers on 12th Jun 2026, per the AI Mode tracker. Generative UI went global in AI Mode on 19th Aug 2026, with notebooks moving into Search.
Hotel booking arrived in AI Mode on 27th Aug 2026, with flight price tracking in more than 180 countries. Gemini 3.5 Flash was later joined by 3.7 and 3.8 Flash as selectable models for paid plans.
