Gemini 3 launches: Everything new, how to try them

Google has officially launched Gemini 3, its newest and most advanced AI model — and the company is calling it its "most intelligent" system yet. The model rolled out across Google products on day one, marking the first time a new Gemini release has gone live in Search at launch.

Gemini 3 represents what Google execs describe as the next major step in their push toward more capable, more context-aware AI. In a note sharing the launch, the company stated that the model incorporates deeper reasoning, stronger multimodal understanding, and enhanced awareness of user intent compared to earlier versions.

What’s new in Gemini 3?

The headline upgrade is reasoning. Google says Gemini 3 is built to understand nuance, break down complex problems, and "grasp depth and context" in ways its predecessors couldn’t. In benchmarking tests, Gemini 3 Pro took the top spot on the LMArena leaderboard with a 1501 Elo score, outperforming both Grok and Gemini 2.5 Pro.

The model also demonstrates significant improvements in academic-style reasoning. On Humanity’s Last Exam, Gemini 3 Pro hit 37.5 percent without any external tools, and on GPQA Diamond, it reached 91.9 percent. It also posted state-of-the-art scores across math and multimodal tasks, including video understanding and factual accuracy.

A new enhanced mode called Gemini 3 Deep Think pushes those capabilities even further. Deep Think improves scores on nearly every benchmark, including a jump to 41 percent on Humanity’s Last Exam and 45.1 percent on the ARC-AGI-2 challenge. It’s designed for the most challenging, long-horizon reasoning tasks.

Where can you use Gemini 3?

Gemini 3 is already live across the Google ecosystem. That includes:

• AI Mode in Search, with more dynamic, generative interfaces and complex reasoning support. (Currently available for Google AI Pro and Ultra subscribers.)

• The Gemini app is getting a redesign, including the My Stuff folder and improved shopping experiences.

• Gemini for developers, available now in AI Studio, Vertex AI, Gemini CLI, and Google’s new agentic development platform Antigravity.

• Gemini Agent, an upgraded system that can complete multi-step tasks like inbox organization, appointment management, and more.

How to try Gemini 3 right now

If you want hands-on time with Gemini 3 immediately, there are a few pathways:

• Use AI Mode in Search (Google AI Pro or Ultra subscription required).

• Open the Gemini app, where Gemini 3 is the default model starting today for most users globally.

• Developers can experiment with AI Studio or Vertex AI, gaining full access to Gemini 3 Pro.

• Enterprise customers can deploy it through Vertex AI and Gemini Enterprise.

Deep Think, the highest-end version, will be rolled out in the coming weeks following additional safety evaluations.
