OpenAI acquires Ona to give Codex persistent cloud agents

OpenAI announced on June 11 that it has agreed to acquire Ona, a company that builds secure cloud execution and orchestration technology for software teams and AI agents. The deal is aimed at Codex, OpenAI's agent for coding and broader knowledge work. According to OpenAI, Codex now has more than five million weekly users, up 400 percent from earlier this year, and its most valuable tasks are increasingly taking hours or days rather than a few minutes.

That shift explains why Ona matters. Today, many AI agents still depend on a local session, a specific laptop, or a temporary sandbox. Ona's technology is designed to give agents a persistent, customer-controlled cloud environment with the tools, codebase, permissions and context needed to keep working over time. OpenAI says that would let Codex continue work after a laptop is closed, while still giving organizations control over infrastructure, data and security boundaries.

Ona confirmed the agreement in its own post, saying it will join OpenAI as part of the Codex team after customary closing conditions and required regulatory approvals. Until the transaction closes, the two companies remain separate. Ona CEO Johannes Landgraf framed the move as a way to bring enterprise AI work beyond individual coding sessions and into cloud-based workflows that can be accessed from a laptop, phone or tablet.

For developers and companies, the news points to the next phase of AI tooling. The early wave of coding assistants mostly helped inside editors. The new wave is about delegation: asking an agent to run tests, investigate bugs, modernize code, prepare changes, document decisions or handle multi-step work across systems. That requires not only stronger models, but also reliable environments where the agent can act safely.

The acquisition also signals that infrastructure is becoming a competitive advantage in AI. Model quality still matters, but enterprise adoption depends on governance, auditability, reproducibility and access control. If OpenAI can combine Codex with Ona's cloud environments, AI agents may become less like chat windows and more like managed colleagues that carry work forward under human supervision.
