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.
OpenAI is the creator of ChatGPT and the GPT series of large language models, having pioneered the commercial LLM API market. Founded in December 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, and others as a non-profit, it transitioned to a capped-profit model in 2019 and is currently restructuring as a for-profit public benefit corporation.
OpenAI's API platform provides access to text generation (GPT-4o, GPT-5, o-series reasoning models), image generation (DALL-E), speech-to-text (Whisper), text-to-speech, and embedding models. The platform supports fine-tuning, function calling, and the Responses API for agent-native workflows. The open-source Agents SDK and tools like code interpreter and web search enable developers to build sophisticated AI applications.
In February 2026, OpenAI closed a record $110 billion funding round from Amazon, Nvidia, and SoftBank, valuing the company at $840 billion post-money. The company employs approximately 3,500-7,200 people and is reportedly targeting a 2027 IPO at up to a $1 trillion valuation.
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.
