Gemini 2.5 Pro Preview: even better coding performance

We’ve seen developers doing amazing things with Gemini 2.5 Pro, so we decided to release an updated version a couple of weeks early to get into developers hands sooner.

Today we’re excited to release Gemini 2.5 Pro Preview (I/O edition). This update features even stronger coding capabilities, for you to start building with before Google I/O later this month. Expect meaningful improvements for front-end and UI development, alongside improvements in fundamental coding tasks such as transforming and editing code, and creating sophisticated agentic workflows.

“We found Gemini 2.5 Pro to be the best frontier model when it comes to "capability over latency" ratio. I look forward to rolling it out on Replit Agent whenever a latency-sensitive task needs to be accomplished with a high degree of reliability.”
– Michele Catasta, President, Replit

Best-in-class frontend web development

Gemini 2.5 Pro now ranks #1 on the WebDev Arena leaderboard, which measures human preference for a model’s ability to build aesthetically pleasing and functional web apps. Drawing on this leading capability, Gemini 2.5 Pro powers Cursor’s innovative code agent and empowers our collaborations with companies like Cognition and Replit. Together, we're pushing the frontiers of agentic programming to unlock new possibilities for developers.
