OpenAI AgentKit is a new toolset that makes it easier for developers to create, deploy, and optimize AI agents using OpenAI models.
The strategic alliance for the supply of chips with AMD has been the big announcement of the DevDay 2025 that the artificial intelligence company celebrated this week. But it was not the only novelty and another of the announcements was based on AI agents (or agentic AI), one of the main technology trends of 2025 and among those that are growing the most in the business sector.
El AgentKit de OpenAI
To create an AI agent, developers must manage complex orchestration, create custom connectors, create evaluation pipelines, and manage other critical tasks. The idea of OpenAI is to make things easier with a set of tools that includes three main components:
- Agent Builder – A WYSIWYG interface for creating and versioning multi-agent workflows.
- Connector registry: A unified location for administrators to manage tools and data.
- ChatKit – A toolkit that allows developers to easily integrate customizable chat-based agent experiences into any product.
AgentKit’s Agent Builder allows developers create agents using nodes drag and drop. They can also run evaluations of their agents and preview executions within a visual canvas as seen in the following screenshot:
To highlight the ‘railings’, a open source modular security layer which protects agents from malicious behavior, for example, by detecting personally identifiable information (PII), jailbreak attempts, and other risks.
Creating an agent is only part of the solution. The agent should be implemented in a way that is intuitive for consumers. Deploying agents with end-user chat interfaces involves managing streaming responses, managing multiple chat threads, designing in-chat experiences, and much more.
The new one focuses on that task ChatKitwhich allows developers to easily integrate chat agents into any application or website. It also allows you to customize the user interface to fit your theme or brand. Improvements will also be implemented in Evals to make it easier for developers to test their agents.
OpenAI AgentKit is now available in beta for all developers. Connector Registry is being rolled out in beta to select API, ChatGPT Enterprise and Edu customers with a Global Management Console. ChatKit and the new Evals improvements are now available to all developers this week.
