Story

Analyst tracking puts Gemini 3.5 Pro inside a GA window of roughly this week, with a confirmed 2-million-token context (double Gemini 3.5 Flash's 1M and the largest in any production frontier model), a Deep Think mode reserved for the $250/month Ultra tier, and multimodal support. (Google) Treat the date as an estimate, it's analyst tracking not a Google announcement, but the 2M-context tier is well-corroborated. Worth watching this week. Though remember the context-rot finding above: 2M of window is not 2M of usable reasoning. Bigger context raises the ceiling, it doesn't fix the rot.
