Summary: OpenAI launches AgentKit for building AI agents

Why It Matters: OpenAI is moving from simple chat models to a full platform for building and managing complex AI agents. This makes it much easier for companies to build their own AI tools without needing a large team of engineers to handle the technical plumbing.

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 creating multi-agent workflows.
• Introduced ChatKit for embedding customizable chat interfaces into other apps and websites.
• Released Connector Registry to help businesses manage data connections in one central place.
• Expanded Evals capabilities with new features like trace grading and automated prompt optimization.
• Added custom tool calls and custom graders to reinforcement fine-tuning for reasoning models.
