Ed Bayes, a designer on the Codex team, described how the tool has changed his own workflow. Bayes said Codex now integrates with project management tools like Linear and communication platforms like Slack, allowing team members to assign coding tasks directly to the AI agent. \u201cYou can add Codex, and you can basically assign issues to Codex now,\u201d Bayes told Ars. \u201cCodex is literally a teammate in your workspace.\u201d<\/p>\n

This integration means that when someone posts feedback in a Slack channel, they can tag Codex and ask it to fix the issue. The agent will create a pull request, and team members can review and iterate on the changes through the same thread. \u201cIt\u2019s basically approximating this kind of coworker and showing up wherever you work,\u201d Bayes said.<\/p>\n

For Bayes, who works on the visual design and interaction patterns for Codex\u2019s interfaces, the tool has enabled him to contribute code directly rather than handing off specifications to engineers. \u201cIt kind of gives you more leverage. It enables you to work across the stack and basically be able to do more things,\u201d he said. He noted that designers at OpenAI now prototype features by building them directly, using Codex to handle the implementation details.<\/p>\n

OpenAI\u2019s approach treats Codex as what Bayes called \u201ca junior developer\u201d that the company hopes will graduate into a senior developer over time. \u201cIf you were onboarding a junior developer, how would you onboard them? You give them a Slack account, you give them a Linear account,\u201d Bayes said. \u201cIt\u2019s not just this tool that you go to in the terminal, but it\u2019s something that comes to you as well and sits within your team.\u201d<\/p>\n

Given this teammate approach, will there be anything left for humans to do? When asked, Embiricos drew a distinction between \u201cvibe coding<\/a>,\u201d where developers accept AI-generated code without close review, and what AI researcher Simon Willison calls \u201cvibe engineering<\/a>,\u201d where humans stay in the loop. \u201cWe see a lot more vibe engineering in our code base,\u201d he said. \u201cYou ask Codex to work on that, maybe you even ask for a plan first. Go back and forth, iterate on the plan, and then you\u2019re in the loop with the model and carefully reviewing its code.\u201d<\/p>\n<\/p><\/div>\n\n","protected":false},"excerpt":{"rendered":"
