I don't hold grudge, GPT-2 wasn't that great of a model, so releasing it would be more of a publicity value. But the blog post already had that purpose.
This project gave me motivation to build the deep learning next token prediction integration for JetBrains because I was using PyCharm at the time. (Eventually, it wasn't continued because it was kind of expensive to host)
I would be taking a grudge against those "friends" to my grave.
