Google Launches “Gemini 3 Deep Think Mode” — AI Reasoning Reaches New Heights
Google has officially rolled out its most advanced artificial intelligence feature, “Gemini 3 Deep Think Mode”, for all Google AI Ultra subscribers. This new mode is being hailed as a significant leap in the AI space, as it is specifically designed to solve complex problems in mathematics, science, and logic. The company claims that this feature can “think” and “reason” like a human, enabling it to handle complex queries and professional tasks in a multi-dimensional manner.
AI Thinking Transformed by Parallel Reasoning
Deep Think Mode is based on Google’s new Gemini 3 Pro model, which offers the ability to explore “multiple hypotheses” simultaneously. This means that the AI analyzes any question or data not in a single way, but from multiple directions at once.
Google has tested this feature across several international benchmarks. Reports indicate that Gemini 3 Deep Think scored 41.0% in the Humanities Last Exam (without tools) and 45.1% on the ARC-AGI-2 test (with code execution). Both results are considered leading performances in the industry. Previously, Gemini 2.5’s “Deep Think” variants had achieved gold-standard performance in prestigious competitions like the International Mathematical Olympiad and the International Collegiate Programming Contest.
Key Features of the ‘Deep Think’ Mode
Google states that this mode is now smarter and multimodal. This means it can analyze not just text but also images, PDFs, charts, and videos. Whether it’s a research document, a data report, or a complex scientific problem, the mode examines it from multiple angles to produce results.
Importantly, the AI processes each step in parallel threads—making it faster and more intelligent than traditional “step-by-step thinking” models.
How to Access ‘Deep Think Mode’
Currently, this feature is available only to users on the Google AI Ultra Plan ($250 per month). Accessing it requires a few simple steps in the Gemini app:
- Open the app.
- Select the “Deep Think” mode in the prompt bar.
- From the model dropdown, choose “Thinking” and “Gemini 3 Pro.”
- Submit your query.
Once the AI completes its analysis, the user receives a notification. The feature is not yet available to Pro Plan users, but it is expected to roll out gradually to more users in the coming months.
Clash with OpenAI: Who Leads?
The AI race between Google and OpenAI has become even more intriguing. By launching Deep Think Mode, Google directly challenges OpenAI’s o1 model.
OpenAI’s “o1” model focuses on step-by-step reasoning, whereas Google’s new “Gemini 3 Deep Think” works on parallel reasoning—simultaneously considering multiple possible answers to reach the best result. Benchmarks suggest that Gemini 3 has outperformed “o1” in tough tasks like ARC-AGI-2. OpenAI’s next version, “o3,” has not yet been released publicly.
Google CEO Sundar Pichai described the feature as “the strongest reasoning capability in AI” and stated that “it represents the biggest step towards human-like thinking in AI.”
Gemini 3 Launched in November 2025
Google’s Gemini 3 model was launched in November 2025. Since then, several major upgrades have been added, including:
- Larger context window (ability to process more data at once)
- Smooth natural language responses (human-like replies)
- Safety and content control features
- Improved planning algorithms
These improvements have made Gemini 3 a premium AI tool for research, data analysis, structured writing, and report generation. The “Deep Think” feature is considered the model’s highest-performance reasoning branch.
Global Impact
In the rapidly growing global tech market, the launch of Deep Think Mode is significant. Content creators, tech bloggers, and data analysts can benefit greatly from this feature. For instance, it can analyze entire market data for budget smartphones, tech trends, or gadget performance in a single prompt.
The education sector is also likely to see increased adoption—especially in STEM (Science, Technology, Engineering, Mathematics) education.
The Next Phase in the AI Race
Experts believe that “Deep Think” is not just a feature but a revolutionary shift in AI’s reasoning style. AI is now beginning to understand not just instructions but also the intent behind them.
In the coming months, Google plans to add smart services under the Ultra Plan, including Veo 3.1 video generation model and Gemini Agent, enabling AI to not only provide answers but also autonomously complete tasks.
Final Word
The rollout of this feature has been completed, and early user reviews suggest that the mode feels more “human-like” and “logical” than ever before. Google’s move demonstrates once again that it is pushing AI beyond chatbots toward human-like reasoning and learning. The coming months promise an even more exciting race, raising the question—“Who will become the world’s smartest AI?”
