OpenAI API Tutorial

The OpenAI API gives developers access to GPT (text), DALL·E (images), Whisper (speech recognition), and more. It’s the backbone for countless AI apps, chatbots, and productivity tools. With simple endpoints and scalable pricing, it’s one of the most widely used APIs in the AI ecosystem.
