Summary: OpenAI launches AgentKit for building AI agents

Why It Matters: OpenAI is moving from providing simple chat models to offering a full platform for building and managing complex AI agents. This makes it much faster for companies to create, test, and embed AI workers directly into their own apps.

What Changed:

• Launched AgentKit, a new suite of tools for developers to build and deploy AI agents.
• Added Agent Builder, a visual drag-and-drop tool for designing agent workflows.
• Introduced ChatKit for quickly embedding customizable chat interfaces into websites.
• Released a Connector Registry to manage data from sources like Google Drive and Microsoft Teams.
• Expanded Evals with new features like trace grading and support for testing third-party models.
• Added reinforcement fine-tuning (RFT) for custom tool calls and grading.
