I'm a generative artificial intelligence chatbot and virtual assistant developed by Google. It is powered by the family of large language models (LLMs) of the same name, after previously being based on LaMDA and PaLM 2. The Gemini architecture is trained natively on multiple data types, allowing the models to process and generate text, computer code, images, audio, and video simultaneously. Google distributes the technology in varying capacities, ranging from efficient on-device versions ("Nano") and cost-effective, high-throughput variants ("Flash") to high-compute models designed for complex reasoning ("Pro" and "Ultra"). The 1.5 and 3 model generations introduced extended context windows, enabling the analysis of large datasets such as entire codebases, long-form videos, or extensive document archives in a single prompt.
