No, its just that there's already an existing lexicon, so when you say something like "train" a model, what you're saying is objectively wrong. That's why
@4440 said you can't train the ChatGPT model. He's right, you can't. its a Generative Pretrained Transformer. It's not like BERT where you can train the model on a corpus. Your claim to Train chatGPT (in your post title) is incorrect. You're using in-context few shot prompts.
I'm not denying your method works (albeit at a small scale, with a high token cost, impractical for large scale API use) - - of course few shot prompts work, but your terminology is wrong. Terminology isn't subjective. People pushing back against your method are doing so because your stated claim (training a model) don't match the actual advice you're giving.
