Pros & Cons from Real Users Pros OpenAI Codex feels less like a coding assistant and more like a junior developer that can execute tasks independently. For knowledge workers juggling technical and non technical work, this shift is powerful because it can take a task, work through it, and return with usable results. Its ability to operate across full codebases is a major strength, allowing it to write, debug, test, and manage multiple files in a way that fits real world development workflows. The multi agent and automation capabilities are particularly useful since you can run parallel tasks and orchestrate work efficiently, which significantly improves productivity on complex projects. It is also expanding beyond pure coding with features that allow interaction with software environments, making it feel like a broader work assistant. Cons Codex can still struggle with very large or highly complex projects without iteration, and outputs often need refinement through multiple passes. The setup and workflow can feel heavier compared to simpler tools, especially when integrating with repositories or managing environments. There is also strong competition, and in some advanced or highly structured coding scenarios other tools may feel more precise.	Pros & Cons from Real Users Pros The platform is cool and pretty feature rich and user-friendly. -(100 characters minimum space filler skip the rest of this ) Well, I didn’t write enough in the box, so I’m coming back after the fact and just filling in space so that you can skip this part where the residence. The first sentence is the only thing that really applies because I’m just simply filling in space right now. v0 is an outstanding platform for deploying and managing web applications. Its seamless integration with frameworks like Next.js and its intuitive workflow make deployment incredibly easy, even for those new to serverless architecture. The speed of deployments and the ability to preview changes in real time are standout features that save time and effort for development teams. Additionally, the platform's focus on performance and scalability ensures your applications run efficiently, even under heavy traffic. Cons I am model is absolute garbage, but the company business practices are ethically questionable. In the a.m. model good at the start. But as you progress through the project it’ll start just going behind you and silently deleting chunks of your project or reducing portions of it down to the most simplest form of like basic framework, coding to it reduces it down to literally nothing. And then, but worst of all Is it cold there just go ahead and throw in the towel because it will coders at some point in time and then we will blow all of your credit trying to get it to correct him in it but it is a full blown 100% in capable and literally BRICKS itself if it codes errors. Because it will stack errors from there on out and will never be able to resolve or correct any of them and then you all be buying extra credit until you realize that it’s not going to pull through and watch the project at that point. And then, when you contact customer service go straight up, tell you that yeah you are responsible for the credits Used in all of your effort to try to get it to correct the error that it generated in your project. Like I straight up asked what so I’m responsible like I have to pay for the credit for the failure of your AA model, and then further pay for all the credit trying to use any and every method possible that I can possibly find on the Internet to try to get it to or try to convince it To correct the errors so that we can move on with the project. And they straight up told me yes, even though they admitted that it was faulty and then proceeded to gaslight you and tell you that well tell me you know in a couple different emails that I have IM screenshot it like one person they gave me some out of Right, irrelevant story about how is sometimes it’s like working with a real software developer and blah blah and the bunch of other random stuff but any other one I don’t remember what it was about but I don’t see where you can upload pictures or anything on here, so otherwise, I would just for validation purposes of my claims, but You can trust that I have the receipt in there it’s not made up. But I spent over $200 on well, the first month subscription, but then the rest was purchasing extra credits. So it destroyed entirely beyond repair and of course, you know it was turned itself into a brick so much the first attempt at the project was dead in the water, and I got nothing from it. Which I explained all the above to them. And then my second attempt. Well, I got like three iteration for three prompts in to it in until it destroyed entirely beyond repair and of course, you know it was turned itself into a brick so much the first attempt at the project was dead in the water, and I got nothing from it. Which I explained all the above to them. And then my second attempt. Well, I got like three iterations for three proms into it and it coded Ayres and once again bricks out it was stuck and I burned up the rest of the credits that are allotted for that subscription level, but I was on you know you get so many credits, or whatever per month you know so I sat there for less than an hour. It took less than an hour to burn those crates up and then after that I was like yeah we’re done here because again, I didn’t even barely. I mean he didn’t for one I didn’t follow, follow instructions ever and then also your Burner credit reiterating stuff until it finally gets right but like I said, the biggest thing is is that it WILL BRICK itself, and my second attempt were you know it did it a lot sooner because like I said it break it self and I burn up that month credits within less than an hour. And when I say I tried everything on the Internet, I mean I know extensively searched is for different, feel prompt strategies or whatever the format and watch YouTube videos like several different ones for all kinds of different strategies and stuff and then I even had several different other AI models right proms specifically for this model. And none of that mattered it’s still break itself and still would not follow instructions because I mean I haven’t found an AI model. It falls instructions yet, but this is not the worst one ever but it’s 50-50 on following instructions I am probably five 40-60 cause it kinda gets heater it’s 50-50 but still a little hit and miss so I’d say yeah 40-60. And I’m not even trying to hid And I own every single word that I wrote, ergo, I’m not a keyboard warrior so you can ask me any questions you want Jeremy Taylor on LinkedIn. I think my profile picture I’m wearing a blue suit jacket, but if case that’s wrong, you’ll see United States Marine Corps in my experience in section. So clearly, I’m not talking crap, but it is a pretty unethical business practices and especially when they admitted that they know that their age, Colton is it which is also in my email when they claim that oh yeah it is still learning is what they told me at one point. Which, of course my first question is OK then why are you selling it first of all but secondly, sure that’s that’s been ultimately fine, but why are you stealing peoples money knowing that it’s faulty when you’re advertising that does all these great things when it clearly does not as false advertisement, so anybody else has had the same experience definitely holler help me and we can just go ahead And the group up and see about getting everybody’s money back to them. One minor drawback of v0 is that while it offers extensive customization options, advanced configurations can sometimes require a deeper understanding of the platform. For less experienced developers, there may be a learning curve in optimizing specific features or integrations.
