Codex is OpenAI’s new AI agent designed to handle tangible tasks, not just chat. Unlike ChatGPT, which helps you brainstorm and ask questions, Codex is built to execute work across files, tools, and workflows. Think of it as a hyper-competent assistant on day one—eager to automate mundane chores, pull data from emails or Slack, create slide decks, fix broken processes, or even build simple apps. It doesn’t require coding skills; it’s for anyone who needs to move projects forward by handing off steps. For instance, you can ask Codex to compile information from multiple sources, update documents, or set up a daily digital organizer. But it’s not autonomous—it still needs your direction and final review to align with your judgment. Why it matters: Codex represents a shift from conversational AI to practical, action-oriented agents, potentially reshaping how knowledge workers delegate routine tasks and focus on high-level strategy.
