Alphabet is already a formidable force in the AI arena

In a blog post, CEO Sundar Pichai marveled at the staggering scale of the company's artificial intelligence (AI) initiatives.

Google's AI Overviews search offering already has 2 billion monthly users. Its Gemini AI assistant app has over 650 million monthly users. Over 70% of Google's cloud computing customers use its AI services. And 13 million developers are building products with its generative AI models.

"And that is just a snippet of the impact we're seeing," Pichai said.

Enter Gemini 3

Judging by the impressive specs of its newest model, Alphabet's standing in the AI race is about to improve even further.

Gemini 3 is Alphabet's most intelligent AI model. It's designed to quickly synthesize information across text, images, video, audio, and code.

Gemini 3 offers state-of-the-art reasoning that's better at understanding the context around a user's request with less prompting. It significantly outperforms Alphabet's previous models on every benchmark, such as mathematics, scientific knowledge, coding, and factual accuracy.

Alphabet's latest model is also designed to deliver responses more directly and concisely, without the clichés and flattery that have annoyed users of other leading models.

Alphabet is making these new tools available today in its search browser's AI Mode, Gemini app, and developer platforms.
