Our Verdict
tool1 wins
Google AI Mode wins because it offers significantly cheaper query costs (10x less than ChatGPT Search for equivalent depth), deeper integration with Google's vast search index, and superior long-form research capabilities. For users who need thorough, well-sourced answers with real-time web data, AI Mode provides a more comprehensive and cost-effective search experience.
Google's launch of AI Mode in Search represents the most significant change to how we search the web since the search engine itself was created. Powered by Gemini 3.5 Flash, AI Mode offers deep research capabilities that go far beyond traditional search results. Meanwhile, ChatGPT Search with GPT-5.5 Instant provides a conversational approach to finding information. This comparison puts both AI search tools through extensive testing across accuracy, speed, cost efficiency, real-time information retrieval, long-form research capabilities, and integration with their respective ecosystems to determine which AI search experience delivers better results for different types of queries.

Google AI Mode is currently available through Search Labs at no additional cost. Google has not announced pricing, but the significantly lower query costs compared to ChatGPT Search suggest it will remain free or very affordable when it rolls out broadly.
ChatGPT Search is excellent for conversational research and synthesis but struggles with the breadth of Google's index. For fact-finding, local searches, and broad queries, Google remains superior. For analysis, recommendations, and creative exploration, ChatGPT Search often delivers better results.
Google AI Mode's deep research feature is superior for academic work. It can search multiple sources, synthesise findings, and track citations more effectively than ChatGPT Search, which has more limited research capabilities.
Google AI Mode may display ads within responses, leveraging Google's ad ecosystem. ChatGPT Search is ad-free but its paid model means costs are passed on through subscription fees or per-query charges.
