The OpenAI API offers programmatic access to OpenAI's language models - including GPT-4o, GPT-4o mini, and the o1 reasoning series - for text generation, code completion, document analysis, function calling, embeddings, and speech-to-text. Products developed with the OpenAI API include AI writing assistants, document Q&A systems, code generation tools, customer support chatbots, data extraction pipelines, and autonomous agents. By 2026, OpenAI API integration is expected to be a standard feature in most new software products.
