Google Gemini 2.5 Deep Think Launches: $250/Month AI Tier Achieves Gold Medal Math Performance

Google has launched Gemini 2.5 Deep Think, its most advanced reasoning model, exclusively for AI Ultra subscribers at $250 monthly, marking a significant leap in AI mathematical and logical reasoning capabilities.

Deep Think employs sophisticated parallel thinking techniques, enabling it to generate multiple ideas simultaneously, consider them in parallel, and arrive at optimal solutions. This approach fundamentally differs from traditional sequential AI reasoning, mimicking how human experts tackle complex problems.

The model processes multimodal inputs including text, images, and audio, making it versatile for diverse analytical tasks requiring deep contemplation and strategic reasoning.

The publicly available version achieves bronze-level performance on the 2025 International Mathematical Olympiad benchmark while operating significantly faster than its gold-medal achieving counterpart, which Google has released to a select group of mathematicians and academics for research purposes.

In comparative benchmarks including Humanity's Last Exam and LiveCodeBench, Deep Think surpassed scores from OpenAI's o3, xAI's Grok 4, and Google's own Gemini 2.5 Pro, establishing new performance standards for accessible AI reasoning models.

Google's $250 monthly subscription represents its highest-priced AI access tier, positioning Deep Think as a premium tool for professionals requiring advanced analytical capabilities. This pricing strategy reflects the substantial computational resources required for the model's parallel thinking processes.

The launch follows extensive testing with select users, incorporating feedback to optimize the balance between reasoning depth and practical usability for daily applications.

Deep Think excels in several key domains:

Iterative Development and Design, particularly in web development where complex problem-solving and multiple solution exploration prove valuable.

Scientific and Mathematical Discovery, leveraging its olympiad-level mathematical reasoning for research and analysis.

Algorithmic Development and Programming, where it demonstrates exceptional performance on challenging coding problems requiring multi-step logical reasoning.

AI Ultra members can immediately access Deep Think through the Gemini application, with Google implementing daily interaction limits to manage computational costs, though specific numerical caps remain undisclosed.

The dual-tier approach—offering both a practical daily-use version and a research-grade gold-medal version—demonstrates Google's strategy of balancing accessibility with cutting-edge capability advancement.

This launch intensifies competition in the premium AI market, particularly against OpenAI's reasoning models and Anthropic's advanced capabilities. The significant monthly cost positions Deep Think as a professional tool rather than consumer application.

Google's approach of releasing breakthrough reasoning capabilities through subscription tiers may influence how other AI companies monetize their most advanced models, potentially establishing new standards for premium AI access.

The parallel release to academic researchers suggests Google's commitment to advancing AI reasoning research while commercializing practical applications. Feedback from the mathematical and academic community will likely inform future iterations and capabilities.

Deep Think represents a significant milestone in making advanced AI reasoning accessible to professionals while maintaining research momentum through academic collaboration.
