OpenAI has unveiled a groundbreaking suite of APIs and developer tools, enabling businesses to create and deploy their AI agents. The introduction of the Responses API and the Agents SDK marks a significant step forward in AI development. These tools allow enterprises and developers to integrate AI into various operations, helping automate tasks such as customer support, research, and data processing. The API is powered by OpenAI’s Computer-Using Agent (CUA) model. OpenAI also announced that its Assistants API will be discontinued in early 2026.
