In the livestream, the employees created an AI stylist agent as an example of how the new developer tools can be leveraged to create more useful AI applications. They gave the stylist agent access to two tools: The ability to search the internet, and access to a private database containing information about the OpenAI employees’ personal style.

The tools are part of OpenAI’s new Responses API, which lets businesses develop custom AI agents that can perform web searches, scan through company files, and navigate websites, much like OpenAI’s Operator product. The Responses API effectively replaces OpenAI’s Assistants API, which the company plans to sunset in the first half of 2026.
