Google’s new Gemini 3 Flash AI model is built for faster output at a lower cost, and functions as well as previous powerful reasoning models, Google said in a press release on Wednesday.
According to benchmark tests, Gemini 3 Flash achieves PhD-level reasoning in the GPQA Diamond test, with a score of 90.4%, and achieved a score of 33.7% (without tools) in Humanity’s Last Exam. These are very difficult tests designed to push AI models and require expert-level knowledge. By comparison, Gemini 3 Pro achieved scores of 91.9% and 37.5%, respectively. Google said Gemini 3 Flash outperforms Gemini 2.5 Pro, which was Google’s top model when it released earlier this year, at three times the speed.

Gemini 3 Flash is available in Google AI Studio and Gemini CLI for developers. For general consumers, it’s rolling out in the Gemini app and AI Mode in Google Search. For enterprise users, Gemini 3 Flash is available in Vertex AI and Gemini Enterprise.
Google said Gemini 3 Flash can be a handy agent for customer support or in-game support, tasks that require fast responses.
“Gemini 3 Flash excels at grasping the nuance of your question to serve thoughtful, comprehensive responses that are visually digestible — pulling real-time local information and helpful links from across the web,” Google said in a blog post.
Gemini 3 Pro and nano banana, Google’s image model, are also landing in AI Mode in Search. They’ll be accessible via a dropdown menu and is only available to AI Pro and Ultra subscribers.
Gemini 3 Flash comes as Google is starting to gain a lead against ChatGPT maker OpenAI. Last month’s release of Gemini 3 reportedly pushed OpenAI into declaring a “code red.” OpenAI has since fought back with last week’s release of GPT-5.2. Anthropic also released a new version of its most powerful model, Claude Opus 4.5, in recent weeks.
