Google has upgraded its Deep Research tool with the experimental Gemini 2.5 Pro model, promising major improvements in how users access and process complex information.

Deep Research acts as an AI research assistant capable of scanning hundreds of websites, evaluating content, and producing multi-page reports complete with citations and even podcast-style summaries.

Previously powered by Gemini 2.0 Flash, the new iteration significantly enhances reasoning, planning, and reporting capabilities. Human evaluators in Google's testing preferred Deep Research's outputs over those generated by OpenAI's equivalent by a ratio greater than 2 to 1.

Users also noted clearer analytical thinking and better synthesis of information across sources.

The Gemini 2.5 Pro upgrade is available now to Gemini Advanced subscribers across web, Android, and iOS platforms.

For those using the free version, the Gemini 2.0 Flash model remains accessible in over 150 countries, continuing Google's push to offer powerful research tools to a wide user base.
