Google AI Mode adds 2.5 Pro & Deep Search for subscribers, agentic AI calling for all

Following the announcement at I/O 2025 in May, Google is rolling out Deep Search to AI Mode, as well as letting subscribers access 2.5 Pro. Free users will get access to AI calling in Google Search.

Google AI Pro and AI Ultra members in the US can now access Gemini 2.5 Pro in AI Mode for more complex “Reasoning, math & code” queries. There will be a new model picker to switch between the “Default” model, which is a custom version in the Gemini 2 family that’s meant for “fast, all-around assistance on most questions.” 

The previously-announced Deep Search, which uses Gemini 2.5 Pro, is also rolling out to US subscribers. Available first on desktop web, you can ask more sophisticated queries and get back longer, more detailed responses after a few minutes.

Behind-the-scenes, Google will issue “hundreds of searches” and reason “across disparate pieces of information” to generate a “comprehensive, fully-cited report.” Deep Search can also ask for more details before starting the research process.

Paying AI Mode customers will be the first to get access, with Google seeing Gemini 2.5 Pro and Deep Search as frontier capabilities that do have costs to them. The goal is to bring it to as many people as possible. 

Make sure you have the existing AI Mode experiment in Labs enabled to get these features as they roll out this week. Like the Gemini app, AI Ultra subscribers will see the highest usage limits. As for broader intentional availability, Google today says:

Meanwhile, Google is launching agentic capabilities that let Search call businesses to get pricing and availability details on your behalf. This is rolling out now in the US.

You then answer a questionnaire on Google Search:

It’s powered by both Gemini models and Duplex technology. This was previously tested in Labs as “Ask for me,” and is now rolling out to all Search users in the US, with higher limits for AI Pro and AI Ultra subscribers.
