Google's Gemini AI app has reached a significant milestone, surpassing 400 million monthly active users, as announced by CEO Sundar Pichai on May 20, 2025.

Pichai highlighted that this growth marks a new phase in the AI platform shift, where extensive research is being applied to real-world scenarios for users globally.

The platform has seen a remarkable increase in developer engagement, with over seven million developers now building with Gemini, a fivefold increase from the previous year.

In addition to user growth, Google is set to release Gemini 2.5 for Search in the U.S., which will enhance the search experience with improved AI functionalities, including a new reasoning mode called Deep Think.

Google is also enhancing its Search features to provide more conversational experiences that leverage generative AI.

To further boost Gemini's appeal and performance, Josh Woodward, who previously led the successful NotebookLM app, has taken over its leadership.

The competitive landscape is heating up, with Meta entering the AI chatbot space, claiming over a billion monthly active users across their platforms.

This surge in competition is driven by the increasing popularity of ChatGPT, which poses a challenge to Google's Search business and underscores the need for a strong competitor in the AI chatbot market.

Gemini's growth is particularly notable as it approaches the user scale of OpenAI's ChatGPT, which had approximately 600 million monthly active users as of March 2025.

Google's broader AI initiatives now reach over 1.5 billion users monthly, showcasing the company's strategy to integrate AI features across its platforms.

The monthly token processing across Google's products and APIs has skyrocketed from 9.7 trillion to over 480 trillion, reflecting a 50-fold increase from last year.

Starting May 20, 2025, Google will roll out an all-new AI Mode for an end-to-end AI Search experience, allowing users to input longer and more complex queries.
