Gemini Advanced subscribers and Google Workspace users with access to the Gemini app can now utilize Deep Research powered by Gemini 2.5 Pro Experimental, presented as the world's most capable AI model based on industry reasoning benchmarks and Chatbot Arena evaluations. This feature functions as an AI research assistant, enhancing the research process from initiation to report generation.

The core methodology for assessing the efficacy of Gemini Deep Research with 2.5 Pro is multi-faceted:

1. Model Capability Benchmark: Gemini 2.5 Pro is quantitatively asserted as the leading AI model based on its performance in "industry reasoning benchmarks" and its comparative standing in the "Chatbot Arena," indicating a competitive evaluation against other large language models across various cognitive tasks.
2. Human Preference Testing: Internal validation involved comparative testing where human "raters preferred the reports generated by Gemini Deep Research powered by 2.5 Pro over other leading deep research providers by more than a 2-to-1 margin." This statistically significant preference ratio (2:1) indicates a superior qualitative output as perceived by human evaluators when compared to established deep research platforms.
3. User-Reported Improvements: Early adopters and users have provided qualitative feedback, "reporting a noticeable improvement in analytical reasoning, information synthesis and generating even more insightful research reports." This attests to an observed enhancement in key cognitive functionalities relevant to complex research tasks, leading to more profound and actionable insights.

Functionally, Deep Research is designed to generate "detailed, easy-to-read reports" across diverse research topics, significantly reducing manual research time. A distinctive feature is "Audio Overviews," which transforms generated reports into a podcast-style conversational audio format, facilitating on-the-go consumption. Access is provided across web, Android, and iOS platforms for Gemini Advanced subscribers. Google Workspace users can access it via the web version of the Gemini app, with mobile app availability pending. Users can activate the feature by selecting "Gemini 2.5 Pro (experimental)" from a drop-down menu and engaging the "Deep Research" option in the prompt bar.
