Gemini is designed to handle multiple types of input—text, images, audio, and video—making it a multimodal model.

In 2024, Google released several versions of Gemini, including:

  • Gemini 1.0: The first generation of models with strong text and coding capabilities.
  • Gemini 1.5: Launched in early 2024, with massive context windows of up to 1 million tokens, improved memory, and better performance across benchmarks.
