OpenAI
The company behind ChatGPT and the GPT series of AI models, one of the leading providers of large language models.
What It Is
OpenAI is an AI research company that builds and operates some of the most widely used language models in the world, including GPT-4o, GPT-4o mini, and the o-series reasoning models. Their consumer product, ChatGPT, introduced millions of people to conversational AI. For builders and operators, OpenAI also provides an API that lets you integrate their models into your own applications, workflows, and automations. The API is the same technology that powers ChatGPT, but accessible programmatically so you can build custom tools on top of it.
Why It Matters
OpenAI’s models are the most widely adopted in the AI ecosystem, which means many tutorials, templates, and tools default to OpenAI as the provider. Understanding what OpenAI offers helps you navigate the landscape, even if you ultimately choose a different provider like Anthropic (Claude) or Google (Gemini). The GPT models are strong general-purpose options, and the API has a large ecosystem of libraries and integrations. However, “OpenAI” and “AI” are not the same thing. They are one provider among several, and comparing options is part of being a smart operator.
In Practice
Many no-code and low-code tools like n8n, Zapier, and Make have built-in OpenAI integrations. When you connect an “AI node” in these platforms, you are often calling OpenAI’s API behind the scenes. Operators frequently compare OpenAI and Claude models side by side to find the best fit for each task in their workflow.
