It seems like hardly a day goes by anymore without a new version of Google’s Gemini AI landing, and sure enough, Google is rolling out a major update to its most powerful 2.5 Pro model. This release is aimed at fixing some problems that cropped up in an earlier Gemini Pro update, and the word is, this version will become a stable release that comes to the Gemini app for everyone to use.
The previous Gemini 2.5 Pro release, known as the I/O Edition, or simply 05-06, was focused on coding upgrades. Google claims the new version is even better at generating code, with a new high score of 82.2 percent in the Aider Polyglot test. That beats the best from OpenAI, Anthropic, and DeepSeek by a comfortable margin.
While the general-purpose Gemini 2.5 Flash has left preview, the Pro version is lagging behind. In fact, the last several updates have attracted some valid criticism of 2.5 Pro’s performance outside of coding tasks since the big 03-25 update. Google’s Logan Kilpatrick says the team has taken that feedback to heart and that the new model “closes [the] gap on 03-25 regressions.” For example, users will supposedly see more creativity with better formatting of responses.
Kilpatrick also notes that the 06-05 release now supports configurable thinking budgets for developers, and the team expects this build to become a “long term stable release.” So, Gemini 2.5 Pro should finally drop its “Preview” disclaimer when this version rolls out to the consumer-facing app and web interface in the coming weeks.
