Google Releases 3 New Gemini Models, 3.5 Pro Still Not Available

Google released three new AI models on Tuesday, all built on Gemini 3.5 Flash. The new models are more token-efficient, faster and more reliable across the board. The tech giant also provided an update on the much-anticipated Gemini 3.5 Pro and what’s to come after. 

Here’s what’s new in the latest Gemini models from today’s announcement.

Gemini 3.6 Flash

Google called 3.6 Flash its “workhorse” model that’s now better at coding, knowledge work and multimodal performance. It also promises reduced token usage by up to 17%, and at a lower cost per token versus its predecessor, 3.5.

Google says it built the model based on both developer and customer feedback. A series of benchmarks shows 3.6 Flash’s gains in performance and average tokens per task compared to its predecessor. 

Gemini 3.5 Flash-Lite

Google’s fastest and most cost-effective model can deliver 350 output tokens per second and “significantly” outperforms previous generations when it comes to agentic workflows, according to the blog post.

Like 3.6 Flash, this model now supports computer use as a built-in tool to take on more agentic tasks. 

Gemini 3.5 Flash Cyber

3.5 Flash Cyber is a specialty model that prioritizes cybersecurity workflows in order to find and fix vulnerabilities. It works alongside an infrastructure agent called CodeMender to help cybersecurity teams quickly identify and patch issues.

According to a separate article from Google DeepMind, the new model is already finding and fixing bugs in Google’s internal codebases in Android, Chrome and YouTube. This model will initially be limited to governments and trusted partners, but access will expand in the future.

Gemini 3.5 Pro is still on the way

While the three latest models are the primary focus for Tuesday’s announcements, Google gave a brief update to its upcoming flagship AI model, Gemini 3.5 Pro. The model is said to currently be in testing with partners, and it plans to make it available as soon as it’s ready. How long that will take is anyone’s guess, but Google’s also already looking ahead to the next generation of AI, too.

Google says it has already begun pretraining for Gemini 4, which will be released at an undetermined date.

Both Gemini 3.6 Flash and 3.5 Flash-Lite are available starting today for developers in the Gemini API via Google AI Studio and Android Studio and the Gemini app. 3.6 Flash is also available in Google Antigravity, and 3.5 Flash-Lite is rolling out to Google Search.
