Most people only see the latest Gemini update. The real story started years before the first public launch.
Google merged Brain and DeepMind in 2023. They named the new model family Gemini because it means twins in Latin. The name also nods to NASA’s old space program that bridged early tests to bigger missions.

On December 6 2023 Google announced Gemini 1.0 with three sizes. Ultra for hard tasks, Pro for everyday work, and Nano for phones. It was built from the start to understand text, images, audio, and video together. The same day it began powering the Bard chatbot.

In February 2024 Bard became the Gemini app. Google also launched Gemini Advanced with the Ultra model for paid users. A new mobile app arrived at the same time.
The next year brought bigger changes. Gemini 1.5 added a one million token context window so it could read huge documents or full codebases in one go. Later versions added thinking modes that reason before answering and native tools for agents.

By late 2026 the family reached Gemini 4 Argon. Google now ships faster models for daily use and stronger ones for coding, agents, and long tasks. The gap between research and product keeps shrinking.
I track these shifts as a Web3 analyst. Real progress shows up in what the models can actually do, not just the version numbers.
