Recent statements from Google DeepMind's new leadership have driven the dispersed odds for the next Gemini Pro model release, with Koray Kavukcuoglu noting in late September that Gemini 4 has entered post-training refinement and will arrive much earlier than year-end through an early output for rapid iteration. Persistent delays on the previously teased Gemini 3.5 Pro—originally eyed for June or July after internal benchmarks fell short—have shifted focus to the more ambitious next-generation large language model, creating uncertainty over whether an October preview or general availability will materialize amid ongoing safety testing and Antigravity integration. Historical release patterns and competitive pressure from rivals favor a possible late-month catalyst, though the market-implied 20.5% chance of no release by October 31 reflects the absence of confirmed timelines.
