Google has recently updated its Gemini 2.5 Pro and Flash models with exciting new features. One of the key additions is the introduction of a 'Deep Think' mode for the Gemini 2.5 Pro model, along with enhancements such as native audio output, computer use capabilities, and thinking budgets for both models.
Enhancements at Google I/O 2025
During Google's I/O 2025 event, the tech giant unveiled updates to its Gemini AI model lineup, building upon the earlier release of the Gemini 2.5 Pro update. The preview of Gemini 2.5 Pro showcased its advanced coding and multimodal reasoning capabilities, which are now complemented by new features like the innovative 'Deep Think' mode.

Both Gemini 2.5 Pro and Flash models now offer enhanced functionalities, including Project Mariner's computer use capabilities and native audio outputs for more natural voice interactions.
Focus on Human Preference Leaderboards
Google has shifted its focus from academic benchmarks to human preference leaderboards like LMArena and WebDev Arena. The provided model card highlights impressive benchmark scores on popular evaluations, although the 2.5 Pro model falls slightly short of the current state-of-the-art scores.

However, Gemini 2.5 Pro excels on human preference leaderboards, dominating English-based tasks leaderboards at platforms like Chatbot Arena and WebDev Arena.
Deep Think Feature
The standout feature of Gemini 2.5 Pro is the 'Deep Think' mode, an experimental enhanced reasoning capability that allows the model to consider multiple hypotheses before generating a response. This feature has showcased remarkable performance on challenging benchmarks, including tasks like the 2025 USAMO math competition and LiveCodeBench for advanced coding tasks.

Google plans to make the 'Deep Think' feature available to trusted testers via the Gemini API before a wider release, as the company continues safety testing and gathering feedback from external experts.
Enhancements for Gemini Models
In addition to the 'Deep Think' mode, Google has made several enhancements to both the Gemini 2.5 Pro and Flash models. These updates include native audio output, computer use capabilities, and improved thinking budgets for enhanced performance.

Overall, the latest updates to Google's Gemini AI model lineup signify a significant step towards more advanced and user-centric AI capabilities.
