I thought the char-by-char teleprinter thing was just an effect (y’know, for user-engagement and to make the interaction feel more genuine) - and that these systems just return output in buffered blocks/pages or whatever-it-is that they wired-up their network to do.
It’s not like DALL-E outputs pixels in scanout order - or in brushstroke order (…er… or does it?)
It's not an effect at all. It calculates and outputs one token at time. The algorithm requires all previous tokens in order to output the next one. DALL-E is a totally different algorithm. It does not have a scanout or brushstrokes.
