Google Delays Gemini 3.5 Pro to July, Missing Its Own June Promise

One-liner: Gemini 3.5 Pro, which Sundar Pichai promised at I/O with a "give us until next month," has missed its June general availability window and is now expected in July 2026.

Key Facts

• Announced at Google I/O on May 19, 2026; Pichai told the live audience "give us until next month" — drawing audible groans — but no GA date has since been confirmed
• Currently in limited Vertex AI enterprise preview only; no public API access
• Planned specs: 2M-token context window, Deep Think reasoning mode, frontier multimodal capabilities
• Prediction-market odds for a June 30 release have collapsed to below 18%

Why It Matters

Gemini 3.5 Pro is Google's head-to-head answer to Claude Fable 5 and the anticipated GPT-5.6 — both already launched or imminent. A month's delay keeps Google's top model off the enterprise procurement shortlist during a window when competitors are actively closing deals. It also adds to a pattern of high-profile Google AI announcement-to-delivery gaps that enterprise buyers are starting to factor into vendor evaluations.
