OpenAI is taking another significant step in its push toward agentic artificial intelligence with plans to acquire Ona, a startup known for building secure infrastructure that enables AI agents to operate over extended periods.
The move highlights OpenAI’s growing focus on developing systems that can do more than simply respond to prompts. Instead, the company is investing in technology that allows AI agents to work continuously, retain context and complete complex tasks without constant human supervision.
The proposed acquisition could have a particularly strong impact on Codex, OpenAI’s coding assistant platform, which has rapidly evolved beyond traditional code generation. By bringing Ona’s technology into its ecosystem, OpenAI aims to equip Codex with the infrastructure needed to handle long running projects and enterprise level workflows more effectively.
Why Ona Matters to OpenAI
Ona specializes in creating secure and persistent cloud environments designed specifically for AI agents. These environments allow agents to access business tools, internal systems and relevant context while continuing their work even after a user has closed a browser window or logged off a device.
This capability addresses one of the biggest challenges facing modern AI systems. While many AI tools can generate content or perform tasks in real time, they often struggle to maintain continuity across longer projects. Ona’s infrastructure solves this problem by giving agents a stable workspace where progress can be preserved and resumed whenever necessary.
OpenAI believes this technology will become increasingly important as businesses adopt AI agents for more sophisticated workloads. From software development and research projects to operational tasks and workflow automation, organizations are demanding AI systems that can work independently for hours or even days at a time.
Codex Could Become Much More Powerful
The acquisition has sparked interest because of what it could mean for Codex. Initially introduced as a coding assistant, Codex has gradually expanded its capabilities and audience. OpenAI says the platform now serves around five million weekly users, reflecting growing adoption across different professional roles.
Integrating Ona’s technology could allow Codex to move beyond short coding sessions and into continuous project execution. Developers may eventually be able to assign complex tasks that require multiple stages, ongoing monitoring and access to various tools without needing to restart the process repeatedly.
For example, an AI agent powered by Codex could potentially analyze requirements, write code, run tests, monitor results and continue refining a project over an extended period. Such functionality would represent a major leap from the current generation of coding assistants that primarily focus on immediate responses and short term tasks.
The result could be a more autonomous development experience where AI contributes throughout an entire project lifecycle rather than at isolated moments.
The Rise of Agentic AI
The timing of the acquisition reflects a broader industry shift. For several years, the artificial intelligence sector concentrated heavily on building larger and more capable foundation models. While that race continues, attention is increasingly moving toward practical deployment and real world execution.
Agentic AI has emerged as one of the fastest growing segments of the market. Unlike conventional AI chatbots that react to user instructions, agentic systems can plan, execute and adapt over time while maintaining awareness of previous actions and goals.
The growth figures shared by both companies highlight this trend. OpenAI reports that Codex has reached millions of weekly users, while Ona says its weekly sessions have increased thirteenfold since the beginning of the year. Those numbers suggest rising demand for AI systems capable of handling ongoing workflows rather than simple one time interactions.
Industry experts view persistent environments, memory management and tool integration as essential components of the next generation of AI agents. OpenAI’s interest in Ona indicates that these capabilities are becoming strategic priorities.
Looking Ahead
The acquisition remains subject to regulatory approval, but both companies appear optimistic about the future. Ona CEO Johannes Landgraf said the team is excited about joining OpenAI’s Codex division and continuing work toward a future where AI helps organizations operate more safely, efficiently and collaboratively.
For OpenAI, the deal represents more than an infrastructure upgrade. It signals a broader commitment to building AI systems that can act independently, maintain long term context and contribute meaningful work over extended periods.
If successfully integrated, Ona’s technology could accelerate Codex’s transformation from a coding assistant into a comprehensive AI work platform. As businesses increasingly look for AI tools that can manage complex tasks with minimal oversight, the acquisition positions OpenAI to play a leading role in the next phase of enterprise AI adoption.
