Google is launching three new Gemini models, but no 3.5 Pro

On Tuesday, Google DeepMind released Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber. Gemini 3.6 Flash is Google’s “workback model” that promises improved programming capabilities, cognitive work, and multimedia performance while reducing token usage by up to 17%, making it cheaper than its 3.5 Flash predecessor.

Gemini 3.5 Flash-Lite The most cost-effective model in its class, the 3.5 Flash Cyber ​​is a specialized model fine-tuned to find and fix cybersecurity vulnerabilities at an affordable price. This model will be available exclusively to governments and trusted partners as part of a limited-access pilot program, according to Google.

Google says the focus of these releases is to provide efficiency, response time, and reliability for customers building large-scale AI agents.

The launch is noteworthy not only for what Google shipped — cheaper, faster, improved models of programming, efficiency, and cybersecurity — but also for what it didn’t deliver. The update does not include the long-awaited update to Google’s flagship model, the Gemini Pro, which was last updated in February.

Gemini Pro models are generally Google’s most capable offerings for complex ideation and programming tasks, while Flash models prioritize lower cost and faster response times for production applications.
