Overview
OpenAI is the AI research organization that created GPT-4, ChatGPT, DALL-E, and Whisper. Founded in 2015 and transitioning from nonprofit to "capped-profit" in 2019, OpenAI has become the most influential player in the AI industry. ChatGPT's launch in November 2022 catalyzed the current AI revolution, reaching 100 million users faster than any product in history.
The company provides both consumer products (ChatGPT, DALL-E) and developer APIs (GPT-4, GPT-3.5, embeddings, Whisper). OpenAI's models are known for their exceptional quality, versatility, and ease of use, making them the default choice for many developers building AI applications.
