Google's Gemini 2.5 Pro is making waves as an experimental AI model, showcasing significant advancements ahead of the official Google I/O 2025 launch. This model is available for developers in Google AI Studio and for Gemini Advanced users via the Gemini app.
Reasoning and Capabilities
Gemini 2.5 Pro is designed as a "thinking model," capable of reasoning through problems to deliver enhanced performance and improved accuracy. Google has been working on making AI smarter through techniques like reinforcement learning and chain-of-thought prompting, building upon previous models like Gemini 2.0 Flash Thinking. Gemini 2.5 Pro combines a significantly enhanced base model with improved post-training.
The model excels in complex tasks, leading on benchmarks that measure human preferences and demonstrating strong reasoning and coding capabilities. It is state-of-the-art across a range of benchmarks requiring advanced reasoning and leads in math and science benchmarks. Without test-time techniques that increase cost, 2.5 Pro also scores highly on Humanity's Last Exam, a dataset designed to capture the human frontier of knowledge and reasoning.
Multimodality and Context Window
Building on the strengths of the Gemini models, the 2.5 Pro maintains native multimodality and a long context window. It ships with a 1 million token context window, with plans to expand to 2 million tokens. This allows it to comprehend vast datasets and handle complex problems from various information sources, including text, audio, images, video, and code repositories.
Coding Prowess
A key area of improvement in Gemini 2.5 Pro is its coding performance. It excels at creating visually compelling web apps and agentic code applications, along with code transformation and editing. The model update was released early in response to positive feedback, allowing users to start building sooner. The I/O edition aims to reduce coding errors and improve how the model handles complex tasks like function calling and code transformation. It is particularly strong at front-end web development and can generate new features in an IDE, such as adding a video player in the style of other apps.
Real-World Applications
Gemini 2.5 Pro supports a variety of tasks, including question answering, multimodal content summarization, multimodal question answering, text content generation, and complex problem-solving. Its advanced reasoning, function calling, and tool use enhance its value as part of an agentic AI workflow. The model can call external functions, generate structured output, execute code, and use search, enabling it to solve multi-step tasks, call APIs, and format responses for specific downstream systems.
Availability and Access
Gemini 2.5 Pro is available in Google AI Studio and the Gemini app for Gemini Advanced users. Enterprise customers can access it through Vertex AI. Google intends to introduce pricing that will enable users to use 2.5 Pro with higher rate limits for scaled production use.
Google I/O 2025
Google I/O 2025, scheduled for May 20-21, is expected to feature major AI advancements, including updates to Gemini AI. The conference will showcase how Gemini models enable the building of new applications and unlock new levels of productivity. It will also explore the flexibility offered by options like Gemma open models and on-device capabilities. The event will highlight AI innovations within Google's ecosystem, previews of Android 16, and updates related to cloud, web, and developer-focused advancements.
