What Is Azure OpenAI Service?
Azure OpenAI Service is a managed platform from Microsoft that provides access to OpenAI's language models — including GPT-5, GPT-4.1, GPT-4o, and the o-series reasoning models — through familiar REST APIs. Developers can integrate natural language processing, text summarization, code generation, semantic search, image generation, and audio capabilities into their applications while benefiting from Azure's reliability, scalability, and enterprise security controls.
