Google has released Gemini 2.5 Deep Think to Google AI Ultra subscribers, a new reasoning model leveraging parallel thinking techniques to tackle complex problems. This approach allows Gemini to generate and evaluate multiple ideas simultaneously, revising and combining them to arrive at optimal solutions. Google says that Deep Think has more 'thinking time' to explore hypotheses and find creative solutions.
Deep Think excels at tasks requiring iterative development and design, such as complex coding and scientific problems. It can formulate mathematical conjectures and reason through scientific literature. Benchmark results demonstrate Deep Think's potential, achieving 84% on the MMMU multimodal reasoning test. Google also reports impressive results on the 2025 US Math Olympiad. Deep Think integrates code execution and Google Search. Google AI Ultra costs $250/month and includes early access to experimental video models, higher limits in tools, a prototype AI agent manager, and 30TB of storage.
