Cloud agents get a managed runtime

What changedOpenAI put the harness behind Codex into a public-beta Agents API. It manages durable sessions, context, orchestration and long-running work while builders choose an OpenAI, partner or self-managed environment. That removes substantial infrastructure work, but the service is still beta and the performance numbers in the announcement are selected customer testimonials.

The useful part

Why it matters

Teams can now buy a managed agent loop while retaining a choice of execution environment, changing the build-versus-buy decision for production automation.

Worth doing

What to do next

Keep in mind

Good to know

The API is a public beta, and the quoted cost, latency and reliability gains are vendor-selected customer reports.
