Google’s next major Gemini AI upgrade has reportedly been pushed back.
According to a report from Bloomberg, Gemini 3.5 Pro – Google’s next flagship AI model – is now running months behind schedule after failing to meet internal performance targets. In particular, it struggled in coding tasks.
Reuters says Google had originally planned to launch the model in June. CEO Sundar Pichai announced that timeline during Google I/O in May.
The reported delay comes at a time when competition between AI companies is intensifying. Google, OpenAI and Anthropic are all racing to deliver more capable models while keeping costs under control for businesses and developers.
According to Bloomberg, Google updated the data used to train Gemini 3.5 Pro late last month in an effort to improve its performance. However, citing current and former employees, the report claims the results still fell short of the company’s expectations. As a result, some engineers and AI researchers are concerned about how the model compares with rival systems.
The timing is notable given the rapid pace of AI launches over the past few months. OpenAI recently released GPT-5.6, following a short delay related to US government national security reviews. Meanwhile, Anthropic temporarily restricted access to its latest models after export control measures before restoring availability with additional safeguards.
For now, there’s no revised launch date for Gemini 3.5 Pro. But if the report is accurate, Google seems willing to delay its next flagship model rather than release it before it meets the company’s own performance goals. This is particularly significant as competition in AI continues to accelerate.
