Open AI Agent
Open AI Agent is an autonomous AI system built using OpenAI's models and infrastructure that can independently perform complex tasks, make decisions, and interact with external tools without constant human oversight. These agents leverage OpenAI's GPT models as their reasoning foundation, combined with function calling capabilities, tool integration, and workflow orchestration to execute multi-step processes autonomously. OpenAI's Computer-Using Agent (CUA) model illustrated this approach: introduced in January 2025 behind the Operator research preview, it combined vision-based screen understanding with reinforcement-learned reasoning to operate graphical user interfaces. Operator was retired on 31 August 2025 and its computer-use capabilities were absorbed into ChatGPT's agent mode.
The Open AI Agents SDK enables developers to build agentic AI applications with lightweight primitives including agents equipped with LLMs, facilitating the creation of production-ready autonomous systems. OpenAI agents can handle diverse applications from web browsing and data analysis to customer service and content creation, representing a significant evolution from traditional chatbot interactions toward truly autonomous AI assistants capable of independent task execution.
