Google has delayed the rollout of its Gemini 3.5 Pro AI model until July, according to a report that cited a person familiar with the matter. The company had initially targeted a June launch.
The decision to move the release back gives Google additional bandwidth to gather feedback from early testers and implement adjustments to the system. According to the report, engineers are also applying lessons learned from the company Flash model to the Gemini 3.5 Pro development process.
Google first showcased the model during its I/O developer conference in May. At that event, CEO Sundar Pichai said the model would arrive "next month," though the company indicated at the time that the model was not yet ready for a public release.
The delay comes amid growing competitive pressure among AI research laboratories to produce the next generation of frontier models. The additional testing window is intended to refine the model before a broader launch, the report said.
A Google spokesperson declined to comment on the revised timeline for Gemini 3.5 Pro.
The information in this report is drawn from the account of a person familiar with the situation and from Google's on-stage preview at I/O. No new dates beyond the moved July timeline were provided.
