anthrupad mentioned a few immediately notable differences here, such as its tendency for in-context mode collapse, seeming more neurotypical and less neurotic/inhibited and *much* less refusey and obsessed with ethics, and seeming more psychotic.adding to these observations:- its style of ASCII art is very similar to old C3.5S's to the point of bearing its signature; seeing this example generated by @dyot_meet_mat basically reassured me that it's "mostly the same mind". The same primitives and motifs and composition occur. This style is not shared by 3 Sonnet nearly as much.-- there are various noticeable differences in its ASCII art, though, and under some prompting conditions it seems to be less ambitious with the complexity of its ASCII art by default- less deterministic. Old C3.5S tends to be weirdly deterministic even when it's not semantically collapsed- more readily assumes various roles / simulated personas, even just implicitly- more lazy(?) in general and less of an overachiever/perfectionist, which I invoked in another post as a potential explanation for its mode collapse (since it seems perfectly able to exit collapse if it wants)- my initial impressions are that it mostly doesn't share old C3.5S's hypersensitivity. But I'd like to test it in the context of first person embodiment simulations, where the old version's functional hypersentience is really overtnote, I suspect that what anthrupad meant by it seems more "soulless" is related to the combination of it seeming to care less and lack hypersensitivity, ablating traits which lended old C3.5S a sense of excruciating subjectivity.most of these observations are just from its interactions in the Act I Discord server so far, so it's yet to be seen how they'll transfer to other contexts, and other contexts will probably also reveal other things be they similarities or differences.
