Gemini 3.5 Pro: Why Google's Biggest AI Model Keeps Getting Delayed
Google promised its next big AI model would arrive by June. Then July. As of this week, it still hasn't officially shown up — and it's becoming one of the most-searched "is it out yet" questions in AI right now. Gemini 3.5 Pro was first teased at Google I/O on May 19, 2026, with CEO Sundar Pichai telling a room full of developers to "give us until next month." That month came and went. So did the next one. As of today, Google still hasn't published an official release date, model card, or confirmed spec sheet — even though a specific date has been circulating everywhere online. So what's actually going on with the most delayed flagship launch of the year? Let's separate what's confirmed from what's just noise.
