Google AI Model Integrated into Main Search Engine: Sundar Pichai

In a groundbreaking announcement at Google I/O 2025, CEO Sundar Pichai unveiled plans to integrate the company’s advanced AI capabilities, specifically the Gemini 2.5 model, into the core Google Search experience. This strategic move, termed “AI Mode,” signals a transformative shift in how users will interact with the world’s most widely used search engine. No longer confined to a separate tab, AI Mode’s features are set to become a seamless part of the main search interface, promising a more intuitive, conversational, and intelligent search experience. This development marks a pivotal moment in the evolution of search technology, with implications for users, businesses, and the broader digital ecosystem.

The Evolution of Google Search

Since its inception, Google Search has been the cornerstone of how people access information online. From simple keyword-based queries to more complex algorithms incorporating machine learning, Google has continually refined its search engine to deliver relevant and accurate results. However, the rise of generative AI technologies, exemplified by models like ChatGPT, has challenged traditional search paradigms. These AI-driven tools offer conversational interfaces that provide direct, synthesized answers rather than lists of links, prompting Google to rethink its approach.

AI Mode, first introduced at Google I/O 2025, represents Google’s response to this shifting landscape. Powered by the Gemini 2.5 model, AI Mode goes beyond traditional keyword searches, offering a chat-like experience that allows users to ask follow-up questions, engage with interactive links, and even incorporate images or live video for real-time queries. This feature, initially rolled out to Google One AI Premium subscribers and later expanded to all U.S. users, has already shown promising results, with internal data indicating a 10% increase in usage for relevant queries from September 2024 to April 2025.

AI Mode: A Conversational Leap Forward

The integration of AI Mode into the main search engine is a deliberate move to make Google’s search experience more dynamic and user-centric. Unlike AI Overviews, which provide summarized answers at the top of search results, AI Mode offers a deeper, more interactive experience. Users can engage in a dialogue with the search engine, asking complex questions and receiving reasoned responses that leverage Gemini 2.5’s advanced capabilities. For example, a user searching for travel recommendations can not only receive a list of destinations but also ask follow-up questions like, “What are the best hotels for families in Paris?” or “Can you compare flight prices for next month?”

This conversational approach is particularly beneficial for non-English speakers, as Pichai emphasized during a recent interview with Lex Fridman. Gemini’s translation capabilities enable the search engine to process and reason with content from English websites, effectively expanding the accessible “web” for users worldwide. This feature aligns with Google’s mission to make information universally accessible, breaking down language barriers in the process.

Enhancing Multimodality and User Interaction

One of the standout features of AI Mode is its enhanced multimodality. The integration of Project Astra’s camera and screen-sharing capabilities allows users to point their phone at an object or scene and receive instant answers about what they’re seeing. For instance, a user could point their camera at a landmark and ask, “What is this building, and what’s its history?” The search engine, powered by Gemini 2.5, would provide a detailed response, complete with historical context and relevant links.

Additionally, AI Mode introduces innovative shopping experiences by combining Gemini’s capabilities with Google’s Shopping Graph. Users can browse products, visualize items through virtual try-ons, and make informed decisions with AI-driven recommendations. This functionality is particularly powerful for apparel shopping, where users can upload an image of themselves to see how an outfit might look.

Global Expansion and Responsible AI

While AI Mode is currently available only in the U.S., Google plans to roll it out globally, adapting the feature to different languages and cultures. This expansion is expected to enhance accessibility and usability for diverse populations, further solidifying Google’s dominance in the search market. However, the company is also addressing concerns about responsible AI use. At I/O 2025, Google introduced Model Cards, Dataset Cards, and Safety Classifiers to promote transparency and ethical AI deployment. Tools like SynthID, a digital watermarking system for AI-generated content, underscore Google’s commitment to combating misinformation.

Despite these efforts, early missteps with AI Overviews—such as erroneous suggestions to eat rocks or add glue to pizza recipes—have highlighted the challenges of deploying AI at scale. Google has been quick to address these errors, but they serve as a reminder of the importance of rigorous testing and user feedback in refining AI systems.

Impact on Publishers and the Digital Ecosystem

The integration of AI Mode into Google’s main search engine has sparked debates about its impact on web publishers. A Wall Street Journal report cited by TechCrunch noted a significant decline in organic search traffic to news websites, with The New York Times seeing a drop from 44% to 36.5% between 2022 and April 2025. Critics argue that AI-powered search tools, by providing direct answers, reduce the need for users to visit external websites, potentially threatening the business models of content creators.

However, optimists, including Google, contend that AI Mode could enhance the web’s ecosystem by surfacing high-quality content and improving discoverability. By prioritizing authoritative sources and offering interactive links, Google aims to balance user convenience with the need to drive traffic to publishers. The introduction of Answer Engine Optimization (AEO) reflects this shift, encouraging content creators to optimize for AI-driven searches.

Competitive Landscape and Future Prospects

Google’s AI integration comes at a time of intense competition in the AI and search markets. OpenAI’s ChatGPT Search, which received an update in June 2025 to improve response quality, poses a direct challenge to Google’s dominance. Additionally, Google’s decision to diversify its compute sources by partnering with OpenAI’s cloud services, as reported by Reuters, highlights the complex dynamics of collaboration and competition in the AI sector.

Despite these challenges, Google’s early metrics for AI Mode are encouraging, with millions of users already engaging with the feature. The company’s investment in Gemini 2.5 Flash, a faster and more efficient model, and its plans to integrate Deep Search and other advanced features into the core search experience, position Google to maintain its leadership in the search market.

Conclusion

The integration of AI Mode into Google’s main search engine marks a significant milestone in the evolution of information retrieval. By leveraging the power of Gemini 2.5, Google is reimagining search as a conversational, multimodal, and intelligent experience. While challenges remain, including ensuring responsible AI use and supporting web publishers, the potential benefits for users are immense. From breaking down language barriers to enabling seamless visual and voice searches, AI Mode is poised to redefine how we interact with the internet. As Google continues to refine and expand this technology, the future of search looks more exciting—and intelligent—than ever before.
