Understanding the Gemini Model Architecture

Gemini models are built upon the foundation of Transformer decoders, enhanced with advancements in architecture and model optimization. These improvements enable stable training at scale and optimized inference on Google's Tensor Processing Units. They are trained to accommodate a context length of 32k, utilizing efficient attention mechanisms such as multi-query attention. The Gemini 1.0 version consists of three main sizes: Ultra, Pro, and Nano, each catering to different application requirements.

Gemini models are designed to handle textual input along with a wide variety of audio and visual inputs, including natural images, charts, screenshots, PDFs, and videos. They can produce both text and image outputs simultaneously. Visual encoding in Gemini models draws inspiration from foundational work on Flamingo with the distinction that Gemini models are inherently multimodal and can natively output images using discrete image tokens.


Video understanding in Gemini models involves encoding the video as a sequence of frames within the large context window. Video frames or images can seamlessly integrate with text or audio inputs. The models can adapt to variable input resolution to allocate more compute resources to tasks requiring fine-grained understanding. Additionally, Gemini models can directly process audio signals at 16kHz from the Universal Speech Model (USM) capturing nuances often lost in naive audio-to-text mapping.

Training the Gemini family of models necessitated innovations in training algorithms, datasets, and infrastructure. Leveraging scalable infrastructure and learning algorithms, the Pro model's pre-training can be completed in a matter of weeks, utilizing a fraction of Ultra's resources. The Nano series of models utilize advancements in distillation and training algorithms to produce small language models suitable for various tasks, such as summarization and reading comprehension, powering next-generation on-device experiences.
