Design Smart Workflows with Agent Builder
How does Agent Builder work? It uses a visual agent builder that lets users drag, drop, and connect logic nodes on a visual workflow canvas. This workflow automation saves weeks of engineering time. Developers can use agent templates, apply custom guardrails, and enjoy full agent versioning support.
The success stories are already clear. Ramp built a finance automation agent in hours instead of months, while LY Corporation designed a work assistant agent in under two hours. Both teams saw a 70% reduction in development time. Such case studies prove Agent Builder turns AI agent orchestration into a visual art form.
Create Custom Chat Experiences Using ChatKit
What is ChatKit used for? It’s a chatbot SDK that makes in-app AI chat smooth, flexible, and fast. Businesses can easily embed chat UIs into apps or websites with the help of ChatKit integration. These conversational agents match brand design and offer real-time assistance.

Big names like Canva and HubSpot already use ChatKit. Canva built a developer support agent in under an hour, while HubSpot’s customer support agents improved ticket resolution time by over 60%. This shows ChatKit isn’t just a tool—it’s the future of AI chat deployment and product chat integration.
Measure and Improve Agent Performance with Evals
How to measure AI agent performance? The Evals feature is the answer. It provides agent evaluation tools for measuring accuracy, reasoning, and reliability. Developers can use model evals, trace grading, and automated prompt optimization to detect weaknesses and improve over time.
What are OpenAI Evals? They’re part of AI model evaluation and enable dataset creation for testing. With tools for agent reliability testing, model grading systems, and third-party model support, Evals ensure that every agent meets real-world demands with precision and consistency.
Reinforcement Fine-Tuning: Push Your Agent’s Limits
What is reinforcement fine-tuning? It’s an advanced learning technique where models improve through feedback and rewards. Reinforcement learning for agents allows custom tool calls and custom graders, improving reasoning accuracy and adaptability.
RFT for GPT-5 offers fine-tuning AI models with incredible depth. Developers can refine how agents think using model training optimization and reasoning model customization. Companies like Carlyle Group, Rippling, and Box reported over 30% better performance after adopting this feature.
AgentKit Integration with ChatGPT and Other OpenAI Tools
OpenAI AgentKit connects easily with ChatGPT, GPT-5, and OpenAI o4-mini, allowing fluid multi-workspace management through API integrations. This connection lets users manage tools, datasets, and workflows in one environment.
For enterprises, this means smoother secure AI development, centralized control through the Global Admin Console, and faster deployment via the Workflows API. Whether used in automation, research, or creative projects, AgentKit vs ChatGPT Apps SDK integration gives teams unmatched flexibility.
Pricing and Availability of OpenAI AgentKit
The AgentKit pricing model is simple. ChatKit and Evals are now publicly available, while Agent Builder and Connector Registry are in OpenAI developer beta. The beta rollout is happening across U.S. ChatGPT Enterprise and educational accounts with Global Admin Console access.
All tools follow standard API access for developers pricing, making OpenAI AgentKit affordable and scalable. Future updates include expanded Workflows API and enterprise-specific data safety layers for enterprise AI deployment.
How to Get Started with AgentKit (Step-by-Step Guide)
How to build an AI agent with OpenAI starts by registering for the OpenAI developer beta. After gaining access, sign into your Global Admin Console to activate Agent Builder. From there, you can use workflow automation tools to design your first multi-agent workflow.
Next, connect your data using Connector Registry and test it with Evals. Once you’re satisfied, deploy using ChatKit for front-end integration. You can read a full tutorial on Techssla.com for detailed setup help.
