Google has released its new Gemini 3 artificial intelligence model, saying its reasoning abilities significantly outclass its previous models.
Gemini 3 is now available as a preview in Google Search and Google’s enterprise products for subscribers in the United States. Google’s previous major release, Gemini 2.5, was rolled out in March.
“We’re introducing Gemini 3, our most intelligent model, that combines all of Gemini’s capabilities together so you can bring any idea to life,” said CEO of Google and parent company Alphabet Sundar Pichai.
“It’s state-of-the-art in reasoning, built to grasp depth and nuance — whether it’s perceiving the subtle clues in a creative idea, or peeling apart the overlapping layers of a difficult problem. Gemini 3 is also much better at figuring out the context and intent behind your request, so you get what you need with less prompting.”
Gemini 3 includes Gemini 3 Pro, its standard model, and will soon feature Gemini 3 Deep Think, an “enhanced reasoning mode”. Deep Think is now available to safety testers before being rolled out to paying subscribers.
In Google Search’s AI Mode, Gemini 3 can create visual layouts with interactive tools, Google said. It will soon be available to all U.S. users.
Gemini 3 Pro scored 37.5% on Humanity’s Last Exam, a reasoning and knowledge test for AI models. Gemini 2.5 had scored 21.6%, while competitor OpenAI’s GPT-5.1 model scored 26.5%.
It also surpasses previous Gemini models in coding, per Google, having outscored Gemini 2.5 by 21.6 percentage points on the Terminal-Bench 2.0 test of autonomous computer use.
According to Pichai, Google’s Gemini app has more than 650 million users each month, and Google Search’s AI Overviews have 2 billion.
Alphabet said last month that its capital expenditures across 2025 would rise to US$91-93 billion, with the goal of expanding its cloud and AI businesses.
Rival OpenAI's GPT-5.1 was released last week, an upgrade to the GPT-5 models it launched in August. The rollout includes both a Thinking model for advanced reasoning tasks and an Instant model for basic queries.
Alphabet's (NASDAQ: GOOG) share price closed at $284.96, down from its previous close at $285.60. Its market capitalisation is $3.43 trillion.
