Google delayed the release of its Gemini 3.5 Pro AI model from June to July to allow additional time for feedback collection and product refinement [1, 2, 3]. The company first revealed Gemini 3.5 Pro at its I/O developer conference in May 2026 [2, 3].
Some users have had limited early access to the model on Google's Antigravity platform and the AI benchmark site LMArena [2, 3]. A source cited by Business Insider said, "The company previously said it planned to roll out the new Gemini 3.5 Pro model in June. However, it is now targeting a July launch as it spends extra time gathering feedback from early testers and tweaking the model" [2].
Google incorporated lessons from its recent Flash 3.5 AI model into Gemini 3.5 Pro to improve token consumption efficiency [2, 3]. The Flash 3.5 model had drawn criticism for consuming tokens too quickly, leading to cost and efficiency issues [3]. According to the Business Insider source, "Google pushed the launch date back so it could spend more time gathering real-world use cases from early testers" [2].
The original planned release date was June 2026, but the revised target for Gemini 3.5 Pro is now July 2026 [1, 2, 3].
