I'm sure that's what Disney's lawyers specified in the contracts and what their execs expect. However, judging by how LLM controls have gone in the past, I'm fully expecting to see a slew of awful content featuring Disney's characters in the days after this launches. OpenAI also probably won't ever be able to actually stop people from generating harmful content with the characters, but the volume of awful stuff will probably eventually slow down as people get bored and move onto the next controversial thing.
