Summary: OpenAI announced on 2026-06-11 the acquisition of Ona, a startup that provides secure, pre-configured cloud environments stocked with tools, file systems, and persistent context for multi-step agent tasks. Ona employees join the Codex division post-closing. Financial terms were not disclosed. Codex reached 5 million weekly active users as of June 2026, up from 3 million in April. Separately, OpenAI announced that OpenAI models and Codex are now accessible through Oracle Cloud Infrastructure credit commitments, allowing enterprises to apply existing OCI spend toward OpenAI API usage.
Why it matters: Ona's persistent cloud environment infrastructure enables Codex agents to maintain working context across long multi-step tasks, directly competing with Anthropic's Claude Managed Agents platform launched the same week.
