Gemini 2.5 Flash is a high-performance generative AI model developed by Google DeepMind, belonging to the "Flash" variant of the Gemini 2.5 series. Designed as a "workhorse" model, it focuses on fast and excellent performance for everyday tasks, providing timely and low-latency responses. Thanks to Google's wake-up support for the "Think" (think) function in Flash models, it allows developers to dynamically control the model's inference process to balance speed, cost, and accuracy.
