Google launches Gemini 2.5 Flash model in preview for developer feedback

In 2025, Google announced the rollout of its new AI model, Gemini 2.5 Flash, in preview format. The model aims to enhance dynamic reasoning capabilities and is available for testing in the Gemini app. Tulsee Doshi, the director of product management for Gemini, stated that the launch is an opportunity for developers to provide feedback on the model's performance, particularly in terms of its reasoning capabilities. While the previous model, 2.0 Thinking, is being replaced by this experimental 2.5 Flash model, the 2.5 Pro variant continues to be available for testing. The feedback gathered during this preview phase is intended to inform future improvements to the AI features, particularly the dynamic thinking aspect, which adjusts the cognitive workload based on input complexity. Both the Gemini 2.5 Flash and 2.5 Pro models incorporate simulated reasoning, referred to as "thinking" by Google. The new feature allows developers to set token limits for thinking or disable it entirely. As developers utilize the model, they will observe how adjustments affect output generation and reasoning accuracy. The motivation behind launching the Gemini 2.5 Flash model at this stage is to better understand user and developer expectations, particularly regarding the dynamic thinking capabilities that automatically adjust to input complexity. In the tech landscape of 2025, Google is positioned amidst fierce competition in the AI space. The company aims to improve its offerings by actively listening to the feedback provided during the preview of Gemini 2.5 Flash. Ultimately, the objective is to create a more streamlined experience for consumers while retaining significant flexibility in AI applications. The collection of data and insights during this initial phase will enhance the model's alignment with user needs and contribute to the evolution of Gemini's capabilities within the broader scope of AI developments in the market. By engaging directly with users during the preview, Google hopes to foster continuous iterations on dynamic thinking, which is critical for maintaining relevance in a rapidly evolving tech environment. The push to improve Gemini's models reflects Google's commitment to delivering cutting-edge AI tools while balancing consumer experience with developer needs. As such, the 2025 AI landscape will be shaped significantly by the findings and adjustments made during this key development period.
