Google Releases Advanced AI Model for Complex Reasoning TasksGoogle has released Gemini 2.5 Deep Think, an advanced artificial intelligence model designed for complex reasoning tasks. Deep Think takes several minutes to produce answers compared to standard AI models that respond in seconds. On Humanity's Last Exam, a multi-subject assessment covering advanced topics, Deep Think achieved 34.8% accuracy versus 20-25% for competing models. Google's premium pricing restricts access compared to standard AI models that are available for free or through lower-cost subscriptions. Google has not disclosed adoption figures for AI Ultra or revenue from its AI services.
