Gemini 3, which could be Google's best large language model, could begin rolling out in the next few days or hours, as the model has been spotted on AI Studio.

Google clearly has high hopes for Gemini 3 in the coding domain. Along with the new model, the company has released Google Antigravity, a new agentic development platform that will likely compete with fast-growing startup Cursor, which sells its own AI-powered integrated development environment (IDE).

After more than a month of rumors and feverish speculation — including Polymarket wagering on the release date — Google today unveiled Gemini 3, its newest proprietary frontier model family and the company’s most comprehensive AI release since the Gemini line debuted in 2023.

Google launches Antigravity, an AI driven IDE built on agent workflows, offering multi model support and automated coding capabilities.

On Tuesday, Google finally launched Gemini 3, which the company claims is the "best model in the world for multimodal understanding and our most powerful agentic and vibe coding model yet." The claim is supported by benchmark data, crowd-sourced Arena results, and more advanced use cases that the chatbot has not previously been able to tackle.

Gemini 3 excels at coding, agentic workflows, and complex zero-shot tasks, while Antigravity shifts AI-assisted coding from agents embedded within tools to an AI agent as the primary interface, Google said.

Google’s Gemini 3 Pro model card has leaked, revealing strong performance in academic reasoning, math, code, and video-based AI tests. The benchmarks show Gemini 3 Pro beating GPT-5.1 and Claude 4.5 in several key areas.
