OpenAI buys Ona to boost Codex with cloud setups

OpenAI just bought startup Ona to give its coding tool Codex secure, ready-to-use cloud environments. Ona's tech helps Codex handle longer tasks and lets users put AI agents into real-world use. It also gives companies better control over infrastructure and security. The deal amount is secret, and Ona's team will join OpenAI to work on Codex. This is part of OpenAI's push to make Codex stronger, after buying Python startup Astral and Apple Xcode plugin Alex Codes, plus launching the GPT-5-Codex model for agent coding.
