Did OpenAI Build the Decisions API in One Week?

Nikunj Handa says the Decisions API work started a week ago and is still very early. He calls the internal use cases pretty obvious. User operations jumped on it to classify support tickets. He also describes a push for low-latency evals that use a language model as a judge. Shawn Wang repeats the timing back as one week. Handa says the Codex app team might pick the Decisions API up and try to do something with it, and he treats that as still early.

First-party OpenAI products are already building fully on the Agents API. Codex security, which just shipped, is built on the Agents API. A meetings product was launching the same day.
