Google has reportedly pushed the general availability of Gemini 3.5 Pro to July 2026, missing the June commitment that Sundar Pichai made to developers at Google I/O on May 19 when he told the audience to give the company until next month. That line drew audible groans from developers in the room who were expecting immediate access. A company spokesperson declined to comment when asked about the revised schedule, and a source familiar with the development process confirmed the July window to analytics insight.

The reported reasons for the delay are early tester feedback pointing to issues with token efficiency and long-horizon task performance. Flash, the model that shipped at I/O, consumes tokens quickly which raises costs on extended prompts and agent workflows. Google is apparently examining those issues before releasing Pro, which is supposed to be the flagship reasoning model for exactly these demanding tasks. The model has a 2-million-token context window and a Deep Think reasoning mode that is gated to the 250 dollar per month Ultra subscription tier.

Prediction markets had been pricing around 50 to 55 percent odds of a June 30 release. Those odds will now shift sharply. The miss is the second consecutive I/O commitment Google has failed to deliver on schedule and it will sharpen questions about execution at DeepMind under Demis Hassabis, who is also now dealing with the high-profile departure of John Jumper to Anthropic. The Gemini franchise remains strong but the gap between announcement and availability is becoming a pattern.
