Google AI develops the Gemini family of multimodal models, capable of processing text, images, audio, and video in a single model. The division traces its roots to Google Brain (founded 2011), which merged with DeepMind (acquired by Google in 2014) in April 2023 to form Google DeepMind under CEO Demis Hassabis.
Gemini models power Google's consumer AI products including the Gemini chatbot, Search AI Overviews, and Workspace integrations. The API is available through Google AI Studio and Vertex AI, offering models from the cost-efficient Flash-Lite ($0.10/$0.40 per MTok) to the frontier Gemini 3.1 Pro ($2/$12 per MTok). Google's generous free tier provides unlimited access to several models, and the 1M+ token context window is the largest among major providers.
Consumer subscriptions range from free to Google AI Ultra at $249.99/month, which includes advanced features like Project Mariner (browser agent) and 30TB cloud storage. Google DeepMind employs approximately 5,600-8,000 people and continues to push boundaries with open-source models like Gemma and foundational research contributions.
xAI is an American artificial intelligence company founded by Elon Musk in July 2023, focused on developing advanced AI systems with a mission to understand the true nature of the universe. The company is headquartered in Palo Alto, California, and became a wholly owned subsidiary of SpaceX following a 2026 restructuring. xAI's flagship product, Grok, is a generative AI chatbot designed to provide insightful responses with wit, sarcasm, and personality. The company also develops infrastructure to support large-scale model training and deployment, offering APIs for embedding conversational AI into third-party applications.
xAI has established itself as a significant player in the competitive AI landscape, leveraging Musk's vision of creating AI systems that enhance reasoning and search capabilities while maintaining a distinctive character. The platform integrates closely with X (formerly Twitter), allowing Grok to access real-time information and engage with users across social media. xAI's technology focuses on making AI more accessible and useful for both enterprise and consumer applications.
The company operates with a focus on scalability and innovation, continuously improving its models and expanding its product offerings. xAI's commitment to developing AI that can tackle complex problems while remaining engaging makes it a unique contender in the generative AI space.
Companies that train and release their own large language models and foundation models. These organizations invest in large-scale model training, publish research, and offer API access to their proprietary models.
