This can’t be true??? The Agent Builder was only released around November last year (2025) and is **now being deprecated**!

I use the managed agent builder with Chatkit UI, for multiple clients, and migrating to manage the backend myself, makes the use of this tool **economically unviable.**

Please confirm that this deprecation means that the ChatKit recommended implementation is also not available.

I trust that OpenAI will revise this decision and continue with the Agent Builder and recommended approach for Chatkit implementations.

> There are two ways to implement ChatKit:
> 
> - **Recommended integration**. Embed ChatKit in your frontend, customize its look and feel, let OpenAI host and scale the backend from **[Agent Builder](https://developers.openai.com/api/docs/guides/agent-builder)**. Requires a development server.
> - **Advanced integration**. Run ChatKit on your own infrastructure. Use the ChatKit Python SDK and connect to any agentic backend. Use widgets to build the frontend.
