Ah such condescension! I was careful not to provide an opinion, but replicate the answer as is. The intent was not to treat that answer as fact; but I thought that response was pretty revealing and in fact supported the parent comment on LLMs having been trained on copyrighted materials. The response chatgpt provided was that OpenAI models are designed to create original content "without directly referencing copyrighted characters". If it was creating original content it needn't have referred to the constraint with respect to avoiding directly referencing the copyrighted characters.
