Google unveiled Gemini 2.5 Pro Preview (I/O edition) on Tuesday, presenting it as an enhanced iteration of its leading Gemini 2.5 Pro AI model, which the company asserts surpasses various prevalent benchmarks.

The Gemini 2.5 Pro Preview, which was shown at the I/O event, can be used with the Gemini API and Google's Vertex AI and AI Studio platforms. It costs the same as the Gemini 2.5 Pro model that it is replacing. You can also find it in Google's Gemini chatbot app for websites and phones.

This model's launch precedes Google's yearly I/O developer conference, explaining the "I/O edition" label. At this event, Google is anticipated to present numerous models, alongside AI-driven tools and platforms. The company is vigorously striving to dominate the market and public attention in the fiercely competitive AI arena; competitors such as OpenAI and xAI are poised to introduce models predicted to exhibit exceptional performance.

Google states that Gemini 2.5 Pro Preview (I/O edition) offers “significantly” enhanced proficiencies in coding and the development of interactive web applications, alongside improvements in tasks such as code transformation, which involves altering code to meet a specific objective, and code editing.

In a blog post, Google highlights that Gemini 2.5 Pro Preview (I/O edition) tops the WebDev Arena Leaderboard, a benchmark evaluating a model’s aptitude for developing visually appealing and effective web applications. Additionally, Gemini 2.5 Pro Preview (I/O edition) demonstrates cutting-edge performance in video comprehension, scoring 84.8% on a widely recognized benchmark, VideoMME.

For developers who are already using Gemini 2.5 Pro, this new version will make coding better and will also fix important issues developers have mentioned, like having fewer errors when calling functions and making function calling happen more often," Google said in its blog post. "Normally, the model really likes making websites look good while still being easy to control."
