Google Enhances Search with Advanced AI Model Gemini 2.5 Pro

In July 2025, Google introduced significant enhancements to its Search platform by integrating the advanced Gemini 2.5 Pro model into AI Mode. This integration brings two notable features: Deep Search and AI-powered local business calling, initially available to AI Pro and AI Ultra subscribers in the United States.

The Gemini 2.5 Pro model represents Google's most sophisticated large language model to date, designed to handle complex reasoning, coding, and mathematical problem-solving tasks. Within AI Mode, subscribers can select this model to receive more detailed and accurate responses to intricate queries. Robby Stein, Vice President of Product at Google Search, highlighted the model's capabilities, stating that it "excels at advanced reasoning, math, and coding questions, helping you with your complex queries with links to learn more."

Deep Search leverages the Gemini 2.5 Pro model to perform comprehensive research tasks. It issues numerous searches, analyzes information across various sources, and generates detailed, fully-cited reports. This feature is particularly useful for in-depth research related to jobs, hobbies, studies, or significant life decisions like purchasing a new house or conducting financial analysis. Stein noted that Deep Search "helps you save hours by issuing hundreds of searches, reasoning across disparate pieces of information and crafting a comprehensive, fully-cited report in minutes."

In addition to Deep Search, Google has introduced an AI-powered calling feature that allows users to have Google contact local businesses on their behalf to inquire about pricing and availability. For example, when searching for services like "pet groomers near me," users can select the "Have AI check pricing" option. Google's AI then calls the businesses, gathers the necessary information, and presents it to the user in a summarized format. This functionality is powered by Google's existing Duplex technology, which enables natural-sounding AI interactions over the phone.

These enhancements are currently rolling out in the United States for Google AI Pro and AI Ultra subscribers. The AI-powered calling feature is available to all Search users in the U.S., with higher usage limits for Pro and Ultra subscribers. Businesses have the option to manage these AI interactions through their Google Business Profile settings, maintaining control over their engagement with the AI system.

The integration of advanced AI models like Gemini 2.5 Pro into everyday tools such as Google Search signifies a shift towards more proactive and intelligent digital assistants. Features like Deep Search and AI-powered calling can significantly reduce the time and effort required for users to gather information and make informed decisions. However, this also raises questions about data privacy, the accuracy of AI-generated information, and the potential impact on businesses that rely on direct customer interactions.

Google has been at the forefront of AI research and development, with initiatives like the Gemini series of language models and the Duplex technology. The Gemini models are designed to handle complex reasoning and problem-solving tasks, while Duplex focuses on enabling natural-sounding AI interactions over the phone. These technologies reflect Google's commitment to enhancing user experiences through AI integration.

The introduction of these AI features could influence various sectors, including local businesses, by altering how consumers seek and interact with service providers. For instance, the AI-powered calling feature may reduce the number of direct customer calls, impacting businesses that rely on such interactions. Additionally, these advancements may affect the competitive landscape among AI service providers and search engines.

Google's integration of AI into its services is not unprecedented. The company has previously introduced AI capabilities like Google Assistant and Duplex. However, the current enhancements represent a more profound integration of AI into the core search experience, offering more proactive and comprehensive assistance to users.

In conclusion, Google's integration of the Gemini 2.5 Pro model into its Search platform marks a significant advancement in AI-driven user assistance. While these features offer enhanced convenience and efficiency, they also prompt important discussions about privacy, accuracy, and the evolving relationship between consumers and businesses in the digital age.
