Today is June 30. Gemini 3.5 Pro is not here.
At Google I/O on May 19, Sundar Pichai introduced the model and, when asked about general availability, said: “Give us until next month.” The audience reaction was muted — Google’s track record with launch dates in 2026 was already shaky.
What we know
Gemini 3.5 Pro remains in limited Vertex AI enterprise preview. Google cites early tester feedback as the reason for the delay — specifically, excessive token consumption during extended agentic tasks and long-horizon performance issues.
On Polymarket, the market for “Next Google Gemini Pro Model released by June 30” closed at 97 percent on No Release. $229,697 in total trading volume. The traders knew.
The talent context
The delay hits Google at the worst possible moment. Between June 18 and 24, four senior researchers left the Gemini team — Noam Shazeer to OpenAI, John Jumper, Jonas Adler, and Alexander Pritzel to Anthropic. These aren’t random departures. These are the architects behind Gemini’s core capabilities.
What comes next
Google is now saying July. Expected specs include a 2-million-token context window, Deep Think reasoning mode (gated to Ultra subscribers at $250/month), and frontier multimodal capabilities.
But July is also when GPT-5.6 Sol is expected to go broadly available. Google will need to deliver something genuinely impressive to avoid being seen as slipping to third place. The next few weeks will determine whether Gemini 3.5 Pro can shift the narrative — or whether the talent exodus has left marks too deep to paper over.
