OpenAI has recently prioritized core product development, including advancements for Codex that enable it to operate macOS applications, signaling a strategic focus on creating a comprehensive desktop AI application. The integration aims to provide users with powerful coding and app control capabilities directly within the familiar ChatGPT mobile interface, streamlining workflows and expanding the AI's utility.
