Working fine.

So, would you like to add any more status codes ?

@reverend jim

So, which version you like ? I guess v3.

@dani

Would you like to add anymore status codes ?
https://en.wikipedia.org/wiki/List_of_HTTP_status_codes

What do you think of ChatGpt's choice of adding Status Codes it deemed important enough to include ?
Have you tried ChatGpt for coding or fixing bugs ?

Full ChatGpt Session is here:
https://chat.openai.com/c/e148266e-337d-4f95-b76a-2b41a2b6c67a
You will need to login to your ChatGpt account, I think.

I have followed some of the posts from around 4 weeks ago.

@brobhaisab, It is quite challenging to ask which version of AI created code (be careful, it does not always return what you think it does :), I prefer my own code with maybe chatgtp etc. as a guideline) will be the best for your application needs. You are the only person that will be able to answer that question as you have created the planning and requirements for your application. The client (if one exist or your own need for the application) describes a problem that needs to be addressed, which serves as the foundation for completing the rest of the software requirements.

Based on these requirements, you need to decide which function will best resolve your problem or need. a Dangerous route which results in a never ending spiral is one where a developer (especially for their own created application) starts adding or subtracting requirements from the original plan/scope as it is then almost guarantied that you will never push your application to market as it is forever evolving.

You need to sit down and commit to a set of plans, develop accordingly and then after initial launch, you can always start adding or changing features of your application.

My 5c worth.
