Google introduces upgraded preview of ‘most intelligent model’ Gemini 2.5 Pro

Google introduced an upgraded preview of Gemini 2.5 Pro, its “most intelligent model yet,” according to a blog post. Building on the version released in May and showed at I/O, this model will be the generally available, stable version starting in a couple of weeks, ready for enterprise-scale applications, the company said. “The latest 2.5 Pro reflects a 24-point Elo score jump on LMArena, maintaining its lead on the leaderboard at 1470, and a 35-point Elo jump to lead on WebDevArena at 1443. It continues to excel at coding, leading on difficult coding benchmarks like Aider Polyglot. It also shows top-tier performance on GPQA and Humanity’s Last Exam, highly challenging benchmarks that evaluate a model’s math, science, knowledge and reasoning capabilities. We also addressed feedback from our previous 2.5 Pro release, improving its style and structure – it can be more creative with better-formatted responses. Developers can start building with the upgraded preview of 2.5 Pro in the Gemini API via Google AI Studio and Vertex AI – where we’ve also added thinking budgets to give developers more control over cost and latency. It’s also rolling out today in the Gemini app.”
