OpenAI Expands Codex Cloud Environments

OpenAI is expanding Codex with reusable cloud development environments that work across devices, a revamped CLI with voice controls, new code review tools, and a security-focused product for scanning repositories and preparing fixes. The update positions Codex as a broader AI coding platform rather than a simple assistant. Reusable environments let developers maintain consistent setups across sessions and hardware, while voice controls and review features aim to speed up everyday engineering work. The security scanner targets the growing need to find and remediate vulnerabilities in large codebases. The launch intensifies competition in AI coding tools from GitHub, Google, and startups.
