OpenAI AgentKit is a comprehensive toolkit for building, deploying, and optimizing autonomous AI agents. It features a visual Agent Builder for designing multi-step workflows, a Connector Registry for managing integrations, and ChatKit for embedding customizable chat interfaces. The platform supports low-code orchestration, prompt and guardrail configuration, and evaluation tools for performance measurement. AgentKit enables both technical and non-technical users to create agents that can automate complex tasks, integrate with popular apps, and operate with advanced reasoning using OpenAI's latest models. Its modular approach streamlines agent development from prototype to production, though integration with unsupported apps may require additional effort.
