Gemini (language model)

Gemini is a family of multimodal large language models (LLMs) developed by Google DeepMind, and the successor to LaMDA and PaLM 2. Comprising Gemini Ultra, Gemini Pro, Gemini Flash, and Gemini Nano, it was announced on December 6, 2023, positioned as a competitor to OpenAI's GPT-4. It powers the chatbot of the same name. In March 2025, Gemini 2.5 Pro Experimental was rated as highly competitive.

• What is Google Gemini? | IBM

  # What is Google Gemini? ## Authors Staff Writer Editorial Lead, AI Models ## What is Google Gemini? Gemini is Google’s large language model (LLM). More broadly, it’s a family of multimodal AI models designed to process multiple modalities or types of data, including audio, images, software code, text and video. [...] ### Universal AI agents Through Project Astra, Google is building on its Gemini models to create a universal AI agent that can process, remember and understand multimodal information in real time. To improve recall and efficiency, Project Astra harnesses caching, continuous encoding of video frames and coupling speech and video input into a timeline of events.14 [...] Unlike generative pretrained transformer (GPT) models that take only text-based prompts or diffusion models used for image generation that take both text and image prompts, Google Gemini supports interleaved sequences of audio, image, text and video as inputs and can produce interleaved text and image outputs.2 ## Gemini AI model versions The Gemini family of multimodal AI models comes in multiple variants. Each variant is optimized for different devices and tasks.

• Introducing Gemini: our largest and most capable AI model

  Now, we’re taking the next step on our journey with Gemini, our most capable and general model yet, with state-of-the-art performance across many leading benchmarks. Our first version, Gemini 1.0, is optimized for different sizes: Ultra, Pro and Nano. These are the first models of the Gemini era and the first realization of the vision we had when we formed Google DeepMind earlier this year. This new era of models represents one of the biggest science and engineering efforts we’ve undertaken as [...] On TPUs, Gemini runs significantly faster than earlier, smaller and less-capable models. These custom-designed AI accelerators have been at the heart of Google's AI-powered products that serve billions of users like Search, YouTube, Gmail, Google Maps, Google Play and Android. They’ve also enabled companies around the world to train large-scale AI models cost-efficiently. [...] This promise of a world responsibly empowered by AI continues to drive our work at Google DeepMind. For a long time, we’ve wanted to build a new generation of AI models, inspired by the way people understand and interact with the world. AI that feels less like a smart piece of software and more like something useful and intuitive — an expert helper or assistant. Today, we’re a step closer to this vision as we introduce Gemini, the most capable and general model we’ve ever built.

• An overview of the Gemini app

  Gemini is an interface to a multimodal LLM (handling text, audio, images and more). Gemini is based on Google’s cutting-edge research in LLMs, which began with the Word2Vec paper in 2013 that proposed novel model architectures that mapped words as mathematical concepts, followed by the introduction of a neural conversational model in 2015. This framework demonstrated how models could predict the next sentence in a conversation based on the previous sentence or sentences, leading to more natural
