We've gone through the original implementation of GPTZero and successfully reverse engineer it. (it gives the same results as original GPTZero). We've also recorded the implementation process which can be found below.

We're also working on a GPTZerov2 (inspired by LLM based transformers and GANs), which would be more accurate, and can detect lines changed by humans.

Please give some feedback on our work.

Thanks
