In everyday conversation, "OpenAI" and "ChatGPT" get used interchangeably a lot, but they actually refer to two different things. This short post explains the difference and what it means for your business in practice.
What Is OpenAI?
OpenAI is a company that does AI research and turns that research into products. While its best-known product is ChatGPT, its portfolio also includes the GPT model family (text generation), image generation tools, and API services. In other words: OpenAI is a company, ChatGPT is one of that company's products.
How Does It Relate to ChatGPT?
ChatGPT is the application that presents OpenAI's GPT models to end users through a chat interface. Those same GPT models can also be integrated into other software (chatbots, automation chains, mobile apps) via OpenAI's API, without the ChatGPT interface.
OpenAI's Other Products
- GPT API: A service that lets developers add text generation/understanding capabilities to their own applications.
- Image/audio tools: Text-to-image generation and speech/audio processing models.
- Enterprise solutions: Versions with extra data security guarantees for in-house use.
What Does This Mean for Your Business?
OpenAI is one of the best-known players in the LLM market — see what is an LLM — but it's not the only option. Anthropic's Claude models (see Opus 5, Sonnet 5) and Google's Gemini solve similar tasks with different price/performance trade-offs. The right choice depends less on brand recognition and more on which model is cost-effective for your task.
