Google DeepMind is rolling out Gemini 2.5 Deep Think, which, the corporate says, is its most superior AI reasoning mannequin, in a position to reply questions by exploring and contemplating a number of concepts concurrently after which utilizing these outputs to decide on the most effective reply.
Subscribers to Google’s $250-per-month Ultra subscription will achieve entry to Gemini 2.5 Deep Assume within the Gemini app beginning Friday.
First unveiled in Might at Google I/O 2025, Gemini 2.5 Deep Assume is Google’s first publicly accessible multi-agent mannequin. These programs spawn AI a number of brokers to deal with a query in parallel, a course of that makes use of considerably extra computational assets than a single agent, however tends to end in higher solutions.
Google used a variation of Gemini 2.5 Deep Assume to score a gold medal at this yr’s Worldwide Math Olympiad (IMO).
Alongside Gemini 2.5 Deep Assume, the corporate says it’s releasing the mannequin it used on the IMO to a choose group of mathematicians and lecturers. Google says this AI mannequin “takes hours to purpose,” as a substitute of seconds or minutes like most consumer-facing AI fashions. The corporate hopes the IMO mannequin will improve analysis efforts, and goals to get suggestions on the way to enhance the multi-agent system for educational use circumstances.
Google notes that the Gemini 2.5 Deep Assume mannequin is a big enchancment over what it introduced at I/O. The corporate additionally claims to have developed “novel reinforcement studying strategies” to encourage Gemini 2.5 Deep Assume to make higher use of its reasoning paths.
“Deep Assume might help individuals deal with issues that require creativity, strategic planning and making enhancements step-by-step,” stated Google in a weblog put up shared with TechCrunch.

The corporate says Gemini 2.5 Deep Assume achieves state-of-the-art efficiency on Humanity’s Final Examination (HLE) — a difficult check measuring AI’s skill to reply 1000’s of crowdsourced questions throughout math, humanities, and science. Google claims its mannequin scored 34.8% on HLE (with out instruments), in comparison with xAI’s Grok 4, which scored 25.4%, and OpenAI’s o3, which scored 20.3%.
Google additionally says Gemini 2.5 Deep Assume outperforms AI fashions from OpenAI, xAI, and Anthropic on LiveCodeBench6, a difficult check of aggressive coding duties. Google’s mannequin scored 87.6%, whereas Grok 4 scored 79%, and OpenAI’s o3 scored 72%.
Gemini 2.5 Deep Assume routinely works with instruments akin to code execution and Google Search, and the corporate says it’s able to producing “for much longer responses” than conventional AI fashions.
In Google’s testing, the mannequin produced extra detailed and aesthetically pleasing internet growth duties in comparison with different AI fashions. The corporate claims the mannequin might support researchers and “probably speed up the trail to discovery.”
Plainly a number of main AI labs are converging across the multi-agent strategy.
Elon Musk’s xAI just lately launched a multi-agent system of its personal, Grok 4 Heavy, which it says was in a position to obtain trade main efficiency on a number of benchmarks. OpenAI researcher Noam Brown stated on a podcast that the unreleased AI mannequin the corporate used to realize a gold medal at this yr’s Worldwide Math Olympiad (IMO) was additionally a multi-agent system. In the meantime, Anthropic’s Research agent, which generates thorough analysis briefs, can be powered by a multi-agent system.
Regardless of the sturdy efficiency, plainly multi-agent programs are even costlier to serve than conventional AI fashions. Meaning tech firms might preserve these programs gated behind their most costly subscription plans, which xAI and now Google have chosen to do.
Within the coming weeks, Google says it plans to share Gemini 2.5 Deep Assume with a choose group of testers through the Gemini API. The corporate says it desires to higher perceive how builders and enterprises might use its multi-agent system.
