OpenAI has agreed to acquire Ona, a startup specializing in secure, pre-configured cloud environments for artificial intelligence agents.

The deal is designed to give OpenAI's coding assistant, Codex, the ability to execute longer-running, multi-step tasks by providing agents with persistent access to tools, systems, and execution context.

The acquisition accelerates OpenAI's push to transition Codex from a reactive code generator into an autonomous agent capable of managing complex development workflows.

By internalizing Ona's infrastructure, OpenAI aims to reduce latency and security friction in agent-to-system interactions, a critical bottleneck for enterprise-grade AI coding adoption.

The move arrives as OpenAI recalibrates its infrastructure strategy.

Earlier this week, the company announced a revamped partnership with Microsoft that will allow it to route workloads across any cloud provider, marking a strategic departure from its previous exclusive reliance on Azure.
