This tool stands out from the pack of “AI coding assistants” by automating actionable, non-trivial development work. In its current research preview, Codex is available only on select OpenAI paid plans and requires two-factor authentication for setup. The demo shows Codex automatically suggesting code fixes, managing tasks via a chat interface, and even preparing pull requests—all while helping developers find bugs, typos, and suggest test coverage improvements. A detailed tutorial is promised in a future release. ## 📖 Main Content: Agentic Codex positions itself as the most robust AI developer assistant yet, able to actively manage repositories, identify bugs, make suggestions, and streamline collaboration through direct pull request creation. Unlike previous “AI coding” tools that mainly autocomplete code or answer questions, Codex proposes and acts on changes within real codebases. Key features include: - Automated identification of bugs, typos, and best practices (e.g., missing dependency arrays, additional test coverage). - Task management via chat, with tasks actively performed by the agent in the background. - Direct integration with repositories, with recommendations reviewed via a diff editor and then committed or discussed on GitHub. - Current limitations include access only for higher-tier OpenAI customers and a research preview status that encourages experimenting with non-critical repos. The video’s tone is upbeat, mildly skeptical but ultimately impressed. The host emphasizes transparency—highlighting both setup hurdles and unexpected strengths, and providing honest surprise at Codex’s efficacy compared to earlier hype cycles for AI developer tools. ### 🗒️ Notes - [**[00:04] Release Context & Availability**](https://www.youtube.com/watch?v=les-wjDcK9U&t=4) - 2025 is dubbed “the year of the agent.” - Codex is only for Teams, Enterprise, and Pro OpenAI customers so far. - Requires secure account setup and repo selection. - [**[00:44] Setup & Safety**](https://www.youtube.com/watch?v=les-wjDcK9U&t=44) - Advises copying non-critical repos for experimentation. - Tool is under research preview. - [**[00:59] Features & Workflow**](https://www.youtube.com/watch?v=les-wjDcK9U&t=59) - Adds tasks like code explanation, bug search, and typo checking by default. - Task chat interface allows users to request or review changes. - Uses the terminal for automated changes and suggestions. - [**[01:52] Pull Requests & Collaboration**](https://www.youtube.com/watch?v=les-wjDcK9U&t=112) - Users can review suggestions, approve, and create pull requests directly. - Merges changes and supports team discussions on GitHub. - [**[01:33] Surprises & Evaluation**](https://www.youtube.com/watch?v=les-wjDcK9U&t=93) - Finds real bugs and missed improvements even in “perfect” codebases. - Suggestions include missing dependency arrays and more comprehensive test coverage. - [**[02:10] Future Promise**](https://www.youtube.com/watch?v=les-wjDcK9U&t=130) - Upcoming detailed tutorial to show advanced Codex features. ## 📖 References: - [Agentic Codex is a Legit Developer Assistant - YouTube](https://www.youtube.com/watch?v=les-wjDcK9U) ## 🗣️ Paraphrase: 1. **Original:** "I thought this project was actually perfect. So, I was honestly surprised that it found quite a few improvements. I mean, a lot of them were typos, but it did catch a missing dependency array and suggested additional test coverage." - **Paraphrase:** Although I believed my project was flawless, Codex surprised me by identifying multiple enhancements. Most were minor, like typos, but it also pointed out a missing dependency array and recommended more thorough testing. 2. **Original:** "A lot of times when you watch a demo of a new tool, it's always better than the actual experience. And although you're going to need to test and evaluate this, it's what every developer has been expecting. Something that helps you catch things that you didn't even think of." - **Paraphrase:** Frequently, demo videos overpromise compared to real-world results, but Codex genuinely delivers on its claims. Developers have long awaited a tool that uncovers overlooked issues—and this agent seems to be it. ## 📰 Newsletter: 🧑‍💻 **AI Alert!** OpenAI’s Agentic Codex is not just another code autocompleter—it’s a genuine step toward autonomous dev assistance. In its research preview, Codex auto-reviews your repos, spots bugs and typos, suggests improvements, and lets you create pull requests from its interface before handing it off to GitHub. Setup’s a breeze (if you’re on Teams, Enterprise, or Pro), but experiment on throwaway repos for now. If you’re tired of fluffy AI tools, Codex just might restore your faith—watch for our in-depth tutorial next week! More details: [Agentic Codex on YouTube](https://www.youtube.com/watch?v=les-wjDcK9U) ## ✅ Action Items: - Assess how Codex (and similar agentic tools) could integrate into DevRel, onboarding, and contributor education for open source projects. - Prepare non-critical repositories for safe experimentation with Codex. - Develop training modules on using AI agents responsibly, including repo safety and review workflows. - Review project workflows to identify which tasks could benefit from automated bug detection, code review, or testing suggestions. - Align documentation and OSPO/DevRel strategies to consider responsible adoption of agentic AI in contributor pipelines. - Prepare comms for transparency about limitations, pricing, and privacy of such tools in open source and enterprise contexts. ## 🧪 Hypotheses: - Codex adoption reduces manual code review workload without loss of quality. - Teams using agentic developer assistants report higher code quality and reduced bug incidence. - Open source contributor onboarding is accelerated with integrated agentic assistance. ### 📊 Methodology: - Controlled pilot studies comparing code quality before/after Codex adoption. - Survey developer teams and open source contributors about their experience. - Analyze repo commit history for bug frequency and time-to-merge metrics. ### ❓ Questions: - What are the risks of giving AI agents push access to production repositories? - How do developers adapt trust and review processes when AI proposes changes? - Where does Codex fall short for complex, multi-repo or legacy codebases? ### 🔮 Future Research: - Examine security implications of autonomous agents making repo changes. - Study the long-term impact on contributor learning and skill development. - - Summary: Got a hold of the brand new Codex from OpenAI and I gotta say, I'm pretty impressed. I got used to watching demos that don't pan out, but this is for real. It will let you choose a codebase and start finding things you didn't know were even there...not just that, it will go ahead and fix them, show you a diff so you can verify what it did and get a pull request going directly from the interface. I'll be doing a full course next week, so stay tuned and follow me for more. Follow Me ======= Blog: https://raybo.org LinkedIn: https://www.linkedin.com/in/planetoftheweb Twitter: https://twitter.com/planetoftheweb - URL: https://www.youtube.com/watch?v=les-wjDcK9U Computers have been getting better and better at coding and earlier this year we declared 2025 the year of the agent but honestly we had nothing to show for that. Today OpenAI released Codex an agentic tool for software development that takes care of common developer tasks automatically and although that sounds like every other new tool we've been hearing about it's a lot more impressive than you think. Now, for right now, it's only available on the teams, enterprise, and the expensive pro plan. It's not available on Plus quite yet. Now, when you first get it, you'll have to do some connecting and making sure that you have a secure two-factor authentication account. Then, you move on to choosing the repo that you want to connect it to. This tool is currently under research preview. So, for right now, I suggest that you make a copy of a repo that you feel safe working with and honestly something you don't mind messing up. The first thing you'll notice is that it started by adding three tasks. One that can explain the code for me, picked a part of the codebase to try to find important bugs. Finally, it can also go through the codebase and find typos. Next, you'll get to a chatting window where you can vibe some additional changes to the codebase if you want to. But notice that it's already busy with some of the tasks that it proposed earlier. And if you click on one of those tasks, you can see that it's using the terminal to take care of things. It started to work on some of those and it looks like it's ready to give me some suggestions on how to improve my code. You know, I thought this project was actually perfect. So, I was honestly surprised that it found quite a few improvements. I mean, a lot of them were typos, but it did catch a missing dependency array and suggested additional test coverage. Let's see the process for taking care of a task. I'll click on this button. Once that task is complete, I can review it in a diff editor. I can create a pull request directly in the tool and then move on to GitHub to view the pull request. Then I can have the usual discussions with my team and merge that into the codebase. Now, I wasn't expecting it to be quite this good. A lot of times when you watch a demo of a new tool, it's always better than the actual experience. And although you're going to need to test and evaluate this, it's what every developer has been expecting. Something that helps you catch things that you didn't even think of. I'll be doing a full tutorial of Codex next week., Agentic Codex Is a Legit Developer Assistant, Ray Villalobos, 01jvdy58hdw2n6r8qznmtk9g80.
