Over the weekend, Google announced on social media that Gemini 2.5 is “taking off” and the company wants to get the thinking AI model “into more people’s hands” ASAP. As such, the experimental version of Gemini 2.5 Pro is now available to all Gemini users, free of charge. However, it remains to be seen how long the AI model will stay free.

The Gemini 2.5 branch will eventually replace 2.0, which was only released in late 2024. It supports simulated reasoning, as all Google's models will in the future. This approach to producing an output can avoid some of the common mistakes that AI models have made in the past.
