Just ahead of its annual I/O developer conference, Google has released a powerful new update to its flagship AI model: Gemini 2.5 Pro Preview (I/O edition). This enhanced version of the already popular Gemini 2.5 Pro promises smarter code generation, improved UI development, and state-of-the-art video understanding — all without increasing costs.
The updated model is now live via the Gemini API, Vertex AI, and AI Studio platforms, and is already integrated into the Gemini chatbot app on both web and mobile devices. Though technically a preview release, this I/O edition is set to replace the existing 2.5 Pro offering for most users.
As Google gears up for major announcements at I/O, the launch of this preview model signals the tech giant’s push to stay ahead in the AI race. Competitors like OpenAI and xAI are rumored to be close to releasing next-gen models with advanced reasoning capabilities, making timing crucial for Google.
But Google isn’t just responding to market pressure — it’s listening to developers. According to the company, this version directly tackles some of the most common complaints about Gemini 2.5 Pro. Expect fewer errors in function calls, better accuracy in triggering them, and significantly enhanced capabilities in building and transforming code.
Notably, Gemini 2.5 Pro (I/O edition) now leads the WebDev Arena Leaderboard, a key benchmark evaluating AI’s ability to design and develop elegant, user-friendly web apps. It also posted a strong 84.8% score on the VideoMME benchmark, marking its dominance in video comprehension tasks.
In a blog post, Google highlighted that this updated model has a “real taste for aesthetic web development,” with smarter UI handling and enhanced steerability. In short, it’s better at doing what developers ask — and doing it in a way that looks great, too.
Whether you’re building interactive apps, refactoring messy code, or analyzing video content, the Gemini 2.5 Pro Preview (I/O edition) offers a smoother, more capable experience — and just in time for what may be Google’s biggest AI showcase yet.
