OpenAI has announced an agreement to acquire Ona, a move intended to integrate Ona’s advanced cloud execution and secure orchestration infrastructure into the rapidly evolving Codex ecosystem.
The announcement comes during a period of massive momentum for Codex, which now sees over 5 million weekly active users leveraging the technology to research, analyze, construct, and automate daily tasks marking a notable 400% surge since the beginning of the year. Originally designed as an assistive tool for software engineers, Codex has matured into a comprehensive system capable of managing multi-step, sophisticated tasks from an initial prompt to final execution.

As the underlying models gain capability, the nature of Codex’s most valuable workloads is shifting from short-duration tasks to sustained operations that unfold over several hours or days. The strategic acquisition of Ona directly addresses the market demand for delegating long-running, ambitious workloads without requiring a human to remain perpetually anchored to a single terminal. Instead, tasks can progress independently in the background, allowing users to safely check in, redirect parameters, approve checkpoints, and audit results remotely.
Ona’s proprietary tech stack provides the foundational, highly secure virtual environments required for AI agents to securely access corporate tooling, legacy systems, and real-time contextual information over extended periods. By transitioning Codex workloads away from being tied to individual client machines or brief browser sessions, the integration will allow organizations to confidently deploy autonomous agents across production-scale environments.
Establishing a Dedicated Digital Workspace for Codex
Ona has spent years perfecting the transition of software development processes from localized physical hardware into highly secure, reproducible cloud infrastructure. Having already supported 2 million developers and managed substantial shared client portfolios, Ona’s technical expertise directly aligns with OpenAI’s roadmap for Codex. It ensures that complex AI agents can continue executing workflows within a company’s secure architecture, even when the user’s laptop is closed.
Scaling Autonomous Operations with Enterprise-Grade Security
For those companies moving beyond the phase of trying out their first AI experiments towards deploying these systems more widely across the enterprise, the most sophisticated language models are just one piece of the puzzle. There can be no doubt at all that these agents operate fully within the parameters of corporate compliance, security, and governance.
Ona’s specialized, customer-controlled execution architecture ensures that AI agents can run directly inside a client’s native cloud environment. Concurrently, OpenAI delivers the underlying intelligence, model optimization, and orchestration layer. This hybrid framework empowers corporate IT departments to maintain complete authority over their infrastructure and data perimeters without degrading the performance or capabilities of the Codex system.
“Agents need more than intelligence; they need a trusted workspace. We built Ona to give agents cloud environments with the context, control and collaboration enterprises require. Joining OpenAI lets us bring that foundation into Codex, helping organizations deploy agents with confidence and giving humans more agency over their work.” – Johannes Landgraf, Co-Founder and CEO, Ona
“Enterprises want powerful agents that can do real work while meeting the security and control requirements of their environments. Ona will help us make Codex easier to deploy securely across production workflows for customers operating at the highest standards of trust and scale.” – Thibault Sottiaux, Core Products Lead, OpenAI
Looking Ahead
The finalization of the transaction remains subject to customary regulatory evaluations and closing conditions. Until the deal officially concludes, both OpenAI and Ona will continue to operate as entirely distinct and independent corporate entities.
Upon closing, Ona’s engineering and product teams will fully merge into OpenAI’s corporate structure. They will collaborate closely with the Codex division to optimize secure, long-running enterprise execution architectures and expand Codex’s deployment footprint worldwide. The combined teams are poised to help software development organizations safely automate sustained processes across the entire software development lifecycle, ranging from continuous test execution and automated bug resolution to application modernization and ongoing vulnerability management.
