Today, developers and enterprises are excited to welcome AgentKit. This brand-new set of tools, including the OpenAI Agent Builder, that simplifies the creation, deployment, and optimization of smart agents. Before, AgentKit, building these intelligent agents often involved handling scattered tools, complex task management without clear version control, and lengthy front-end work. Now, with AgentKit’s integrated approach, designing agent workflows becomes faster and much easier.

What Makes AgentKit Special?

Visual Workflow Design with Agent Builder

The heart of AgentKit is the OpenAI Agent Builder, a visual tool that allows developers to create multi-agent workflows by dragging and dropping nodes onto a canvas. Furthermore, this feature supports preview runs to test your agents before launch, inline evaluation setup to monitor performance closely, and full version control for smooth updates. For example, companies like Ramp can now build buyer agents in just hours instead of months . thus, cutting iteration times by over 70%. Consequently, this rapid development helps teams stay aligned across product design, engineering, and ethics fields.

Centralized Management Through Connector Registry

The Connector Registry acts as a central hub where admins can manage data connections across various OpenAI products. It gathers popular pre-built connectors such as Dropbox and Google Drive into one place for easy access. Additionally, enterprises can maintain safety by using built-in Guardrails. Specifically,this is open-source safety layer that flags personal data or suspicious agent behaviors.

Enhancing User Interaction and Evaluation

Easier Embedding with ChatKit

ChatKit takes the hassle out of adding chat experiences to websites or apps. It manages tricky aspects like streaming replies and threading conversations seamlessly while matching the app’s style to provide natural user interactions. With this tool already powering customer support bots at companies like HubSpot, ChatKit makes smart conversations accessible for many products.

Improved Performance Testing Using Evals

The new Evals capabilities help make sure agents work reliably in real-world settings. Developers can now create detailed datasets quickly for testing purposes, automate grading with trace reports that identify weak points in workflows, optimize prompts automatically based on feedback data, and even evaluate models from other providers—all within one platform.
