Has AI Started 'Truly' Thinking? The Changes Brought by Google Gemini's 'Deep Think'

Introduction: Is an Answer Given in One Second Always Correct?

The AIs we’ve been using, like ChatGPT and Gemini, have been like masters of quiz shows. They poured out answers in the blink of an eye as soon as a question was dropped. But what about the truly difficult problems in our daily lives? When solving math challenges or planning complex business strategies, we don’t speak immediately. We pause in silence, imagining various scenarios in our heads like ‘What if I do this?’ or ‘No, that way is better,’ and think deeply.

Google’s recently introduced ‘Deep Think’ in the Gemini app is a groundbreaking feature that transplants this human ‘careful deliberation process’ into AI. Deep Think in the Gemini app Now, AI has started to move beyond simply reciting known information quickly and has begun to perform deep reasoning—the logical process of drawing conclusions—by reviewing and correcting its own logic. Deep Think is available now in the Google Gemini App

Why Is This Important?

Until now, AI often made silly mistakes on problems with complex logical structures or high-difficulty math problems. Metaphorically, it was like an impatient student raising their hand and writing down an answer before even finishing the reading of the problem. However, the emergence of Deep Think means that AI is beginning to focus on the ‘depth of thought’ rather than the ‘speed of thought.’

This technology is especially highly anticipated by mathematicians and scholars who require high-level expertise. In fact, mathematicians like Michel van Garrel are already using this model to test complex mathematical conjectures that are difficult for humans to solve. Try Deep Think in the Gemini app AI’s potential as a ‘partner’ who puts their heads together with experts has opened up, moving beyond the role of a secretary who just does what they are told.

Easy Understanding: The Core Principles of Deep Think

To understand how Deep Think differs from existing AI, you only need to remember two core concepts.

1. Parallel Thinking

A simple analogy for this is a ‘brainstorming meeting.’ While existing AI created answers one sentence at a time by itself, Deep Think creates numerous ‘selves’ in its mind the moment it receives a question. Each alter ego tries different solutions simultaneously. Google’s new Deep Think feature is here — what it does and why it might not stay ultra-exclusive for long

2. Inference Time Extension

While existing AI gave answers in 0.5 seconds as soon as it received a question, Deep Think takes enough ‘thinking time’ before giving an answer. In technical terms, this is called ‘Inference Time,’ and simply put, it is deliberately increasing the physical time the AI spends calculating to derive an answer.

Shall we look at an example?

• General AI: “The answer to this problem is A.” (Immediate answer)
• Deep Think AI: “Hmm… I thought it was A at first, but after re-examining it, there’s a variable B. Considering B, C might be a better answer. I finally recommend C.” (Answer after several seconds of deliberation)

Current Status: Olympiad Gold Medalist Level Skills

To prove the performance of this feature, Google had it solve problems from the International Mathematical Olympiad (IMO), one of the world’s most rigorous intelligence test beds. Surprisingly, one version of the Deep Think model achieved gold-medal-standard results in this competition. Try Deep Think in the Gemini app AI showed top-tier skills on a stage where the smartest young mathematicians from all over the world gather to compete.

This amazing feature is based on the Gemini 2.5 model and is currently being rolled out sequentially through the Gemini app for Android. Gemini 2.5: Deep Think is now rolling out Deep Think is now available on the Gemini app for Android Gemini 3 Deep Think is Out Now: Here’s how to access it

What Happens Next?

The emergence of Deep Think shows that the global AI competition is shifting from ‘how much data has been learned’ to ‘how deeply can it think.’ Since it was first previewed at Google I/O in May 2025 and began to be fully deployed in August, this feature is likely to be expanded to more users as technical efficiency increases in the future. Gemini 2.5 Deep Think rolling out now for Google AI Ultra Deep Think is available in the Google Gemini App. How to try it.

In the future, we will more frequently encounter AI in our daily lives that goes beyond simply getting the right answer to test questions, helping with new scientific discoveries, performing complex legal reviews, and even enjoying high-level strategy games with humans.

AI’s Perspective: A Word from MindTickleBytes

Artificial intelligence has begun to take on the aspect of a ‘deeply pondering philosopher’ beyond a ‘well-spoken parrot.’ Deep Think will fundamentally change the way we treat AI as a tool. The day is not far off when we will find greater value in the process of pondering and refining logic with AI, rather than just demanding fast answers. Thinking AI, where is the end of its depth?
