Google has reportedly delayed the release of Gemini 3.5 Pro, the company’s flagship artificial intelligence model, as internal work continues on improving its performance. According to Bloomberg, the launch is running months behind schedule.

The report says Google has been spending more time refining the model’s capabilities, with a particular focus on coding. That suggests the company is aiming to strengthen Gemini’s output in one of the most closely watched areas of competition in the AI market.

A delay for a major Google AI release highlights the pressure facing large technology companies as they race to deliver more powerful and reliable models. Performance gains are important, but so is meeting internal targets for quality before a product is broadly introduced.

Gemini remains central to Alphabet’s wider AI strategy, making any shift in timing notable for the industry. If the reported delay reflects a push for better coding results and stronger overall capabilities, it underscores how difficult it is to move cutting-edge AI systems from development to launch.
