i'm fully in the hype camp. it's hard to explain the qualitative jump in capabilities but with prior models, i would drop in code (often its own earlier output) and ask for potential next steps and recommendations. the way opus cut things up often felt not properly thought out
so then its recommendations (i.e. do 1 , 2 and 4 of the potential improvements) would seem off, either in terms of priority or even more fundamentally in terms of architecture where #3 in the list was a much higher impact fix that would eliminate the need to do 1, 2, and 4
so more often then not i would ask it to do only a single item on the list or something not even on their list that superceded their proposed "improvements"
with Fable it's the exact opposite. they will return a list of 12 items and suggest doing the first 4 as a sensible push. but my response was actually, "well if you're able to understand the problem and paths forward at this level of sophistication, just go ahead and do all 12 in one go"
i don't get the crazy hype about mythos. i thought the model was unimpressive in every single interaction i've had with it
my sense is it's the same size improvement we saw from opus 4.6 to opus 4.8. it's not something to get this excited about
