There could be a huge business model here, cut costs massively on new TV shows or cartoons getting c churned out.
The script is probably written by just asking chatGPT (for a script). Might even have some prompts that seed the script.
Then the output of the chatGPT is fed into a TTS (text to speech) and played.
I think the laugh track is randomly played (or played in between different scripts that GPT generates). And i can't tell if the music is generated, or just repeats and is only for some scenes.
Quite genius actually.
Tho i would imagine trying to get that working is a lot more work than just randomly choosing a set of pre-animated videos. I suppose if the video doesn't need to sync with the text, then you can create a large bank of them, and choose based on keywords from the text.
