A Quick Look Back: The Gemini Evolution

The Gemini series was introduced by Google DeepMind as a unified, multimodal AI platform capable of handling text, images, audio, code, and even video. While Gemini 1.5 Pro was a leap ahead in reasoning and context length, Gemini Flash was optimized for speed and efficiency. But now, Gemini 2.0 Pro enters the scene, and it's being pitched as Google’s most capable model to date.

With AI increasingly becoming central to coding, content creation, analytics, and operations, this evolution of Gemini is believed to be more than just a performance upgrade, it’s about reshaping how we interact with technology.
