We’ve seen developers do great things with Gemini 2.5 Pro. Therefore, we decided to release the updated version a few weeks early to get it into the hands of developers faster.
Today, we are excited to release Gemini 2.5 Pro Preview (I/O Edition). This update includes even more powerful coding features that you can start building before Google I/O later this month. In addition to improvements in basic coding tasks such as translating and editing code and creating advanced agent workflows, expect meaningful improvements in front-end and UI development.
“We found the Gemini 2.5 Pro to be the best Frontier model when it comes to ‘capacity to latency’ ratio. We look forward to deploying it with Replit Agent whenever we need to reliably perform latency-sensitive tasks.”
– Michele Catasta, President of Replit
Best-in-class front-end web development
Gemini 2.5 Pro currently ranks #1 on the WebDev Arena leaderboard, which measures human preference for a model’s ability to build beautiful and functional web apps. Leveraging this great feature, Gemini 2.5 Pro powers Cursor’s innovative code agent and powers collaborations with companies like Cognition and Replit. Together, we push the frontiers of agent programming and open new possibilities for developers.
“The updated Gemini 2.5 Pro achieved the best performance in our junior development evaluations. It was the first model to solve one of our evaluations that involved a major refactoring of the request routing backend. We felt like a more senior developer because we made the right decisions and chose the right abstractions.”
– Silas Alberti, Cognition Founding Team
Gemini 2.5 Pro in action
Gemini 2.5 Pro’s combination of deep code understanding and powerful reasoning continues to make it the go-to model for developers. We are particularly excited about how this model can be used to:
From video to code
Gemini 2.5 Pro scores 84.8% on the VideoMME benchmark, delivering state-of-the-art video understanding. Combining this with coding enables new flows that were not possible in previous versions. For example, Google AI Studio’s Video to Learning App shows how Gemini 2.5 Pro can create an interactive learning app based on a single YouTube video. The updated Gemini 2.5 Pro model with improved video understanding and a complete UI provides a more functional experience than the previous simple example.
Feature development becomes easier
Gemini 2.5 Pro is great for front-end web development and helps you get more work done. Implementing new functionality means manually accessing the design files, inspecting the components for matching style properties such as color, font, padding, margins, borders, etc., and then manually writing the necessary CSS code to precisely replicate those visual properties. Now imagine using Gemini 2.5 Pro in your IDE and having your model generate new functionality, such as adding a video player in the style of other apps in the Gemini 95 starter app.
Simple concepts to get the app working
Gemini 2.5 Pro makes it easy to bring your ideas to life with both functionality and beautiful UI. The new Dictation Starter app, built using the updated model, is a great example of this in action. Notice details like wavelength animations, responsive design, and subtle button hover effects. By default, this model has a true taste of beautiful web development while maintaining usability, helping developers quickly turn concepts into working web apps. Gemini 2.5 Pro was able to design and code the microphone UI animation for the Dictation Starter app.
Start building with Gemini 2.5 Pro
You can build Gemini 2.5 Pro using Google AI Studio’s Gemini API, and enterprise customers can use Vertex AI.
For developers already using Gemini 2.5 Pro, this new version not only improves coding performance, but also addresses key developer feedback, including reduced function call errors and improved function call trigger rate. The previous iteration (03-25) now points to the latest version (05-06), so you don’t need to do anything to use the improved model and it’s still available at the same price. We have also updated the model cards with the new version 2.5 Pro.
We can’t wait to see the amazing apps you build!
