The Gemini Model Family

Definition

Gemini is Google's multimodal model family developed by Google DeepMind and integrated into Google products and developer platforms.

What is Gemini?

Gemini is Google's family of multimodal large language models developed by Google DeepMind. Google announced the first Gemini generation in December 2023, originally with Ultra, Pro and Nano variants aimed at different compute environments.

How Gemini changed over time

Gemini 1.5 expanded long-context capabilities in 2024. Later generations moved further toward multimodality, reasoning, tool use and agentic workflows. Gemini models power Google's Gemini assistant and are exposed to developers through Google AI and cloud platforms.

Why the family has several tiers

Google uses different Gemini tiers for latency, capability and deployment constraints. Flash models emphasize speed and efficiency, while Pro-tier models target more demanding tasks. A family name therefore does not describe one fixed model size or performance profile.
