About OpenAI API

The OpenAI API is a cloud-based interface that allows developers to integrate OpenAI's powerful machine learning models, such as GPT-5.5 for text and code generation, o4-mini for efficient reasoning, and GPT-Image for image creation, directly into their applications. It supports a wide range of capabilities including natural language processing, computer vision, audio transcription, and code assistance, enabling the creation of chatbots, content generators, and automated workflows without managing underlying AI infrastructure.
