Welcome to Tech Brief, I’m your host. Today, OpenAI just released Codex, a new agentic coding tool built right into ChatGPT. According to the company, “all the user needs to do is input a prompt and then click a button labeled ‘Code.’” Codex can read and edit files, run commands, and even “probe a user’s codebase and answer questions about it” with a click of the “Ask” button. Typical task completion takes “between 1 and 30 minutes,” depending on complexity, and every step is fully auditable through terminal logs and test outputs. The code runs in an isolated environment before you integrate it locally or push to GitHub. While Codex promises to turbocharge development, it also raises tough questions about the future of software jobs: why pay a senior engineer when a junior plus Codex could deliver polished code? OpenAI says it has built-in safeguards to refuse malicious requests, though details remain scarce. Codex is now in research preview and free for ChatGPT Pro, Enterprise, and Team subscribers, with broader access and pricing tiers coming soon.
