OpenAI will reprice Codex for coding-heavy usage
Within the next quarter, OpenAI will introduce a cheaper or more generous pricing path for Codex API usage that is explicitly optimized for coding and agentic workflows. The change will not be a generic model price cut; it will be a packaging move aimed at defending developer mindshare against Claude Code and Cursor.
