# Google Gemini 3.5 Pro targets July 17 launch after architectural rebuild

> Google's next flagship model, Gemini 3.5 Pro, is reportedly targeting general availability today, capping a bumpy path to release. The model was announced at I/O on May 19 for a June launch, but Google scrapped the original version after it hit structural problems, including recursive tool-calling failures, and rebuilt it on a new pretraining foundation. Leaked details point to an ambitious spec sheet: a 2-million-token context window, a Deep Think reasoning layer, and support for autonomous, multi-step workflows. Google has not published a model card, pricing, or even an official confirmation, so the specifics remain unverified for now. The delay is itself informative. Frontier models are now complex enough that agentic behaviors like tool use can break in ways that force a full redo, and labs are increasingly willing to slip timelines rather than ship something unreliable. If the rumored context window holds, it would push Gemini toward workloads, like reasoning over entire codebases or document sets, where memory, not raw smarts, is the bottleneck.
