Gemini 2.5: A New Era in Reasoning AI Models
What are Reasoning AI Models?
Reasoning AI models are designed to "think before they speak." They evaluate context, process details methodically, and fact-check responses to ensure logical accuracy. These capabilities demand more computing power and higher operational costs.
Evolving beyond ‘Flash Thinking’
Google previously launched its first reasoning AI model, Gemini 2.0 Flash Thinking, in December. Marketed for its agentic capabilities, Flash Thinking was recently updated to allow file uploads and larger prompts. However, with the introduction of Gemini 2.5 Pro, Google appears to be retiring the "Thinking" label altogether.
Benchmark Leader in Science, Math, and Code
Gemini 2.5 Pro excels in academic reasoning benchmarks, scoring 86.7% on AIME 2025 (mathematics) and 84.0% on the GPQA diamond benchmark (science). On Humanity’s Last Exam, a broad test featuring thousands of questions across mathematics, science, and humanities, the model leads with a score of 18.8%.
Software Development Benchmarks
In software development benchmarks, Gemini 2.5 Pro performance is mixed. It scored 68.6% on the Aider Polyglot benchmark for code editing, outperforming most top-tier models. However, it scored 63.8% on SWE-bench Verified, placing second to Claude Sonnet 3.7 in broader programming tasks.
Creating Visually Compelling Web Apps and Agentic Code Applications
Gemini 2.5 Pro excels at creating visually compelling web apps and agentic code applications, as evidenced by its ability to create a video game from a single prompt.
Context Window and Future Plans
The model supports a context window of one million tokens, meaning it can process the equivalent of a 750,000-word prompt, or the first six Harry Potter books. Google plans to increase this threshold to two million tokens in the coming weeks.
Availability and Pricing
Gemini 2.5 Pro is currently available through the Gemini Advanced app, which requires a $20-a-month subscription, and to developers and enterprises through Google AI Studio. In the coming weeks, Gemini 2.5 Pro will be made available on Vertex AI, Google’s machine-learning platform for developers, and pricing details for different rate limits will be introduced.
Conclusion
Gemini 2.5 Pro represents a significant milestone in the development of reasoning AI models. With its enhanced capabilities and performances, it has the potential to revolutionize the way we approach tasks and applications that require complex reasoning and problem-solving.
