Google delays Gemini 3.5 Pro to July 17 for a full architecture rebuild
Google is scrapping the existing 2.5 Pro architecture after enterprise testers flagged excessive token consumption in extended agentic tasks.
Google DeepMind has pushed the release of Gemini 3.5 Pro to July 17, after missing an earlier June target that Sundar Pichai had signaled at Google I/O.
Why the delay
Google says the rebuild responds directly to enterprise tester feedback about excessive token consumption during extended agentic tasks — a costly failure mode for any team running the model in production loops.
- ▸The existing 2.5 Pro architecture is being scrapped, not patched
- ▸A full architectural rebuild is underway rather than an incremental update
- ▸The new target date is July 17, 2026
The tradeoff Google is making
Shipping late but fixing a token-efficiency problem at the architecture level is a bet that a slower, more expensive-to-run rebuild beats patching around a flaw that would otherwise resurface in every future release built on the same foundation.
