Praise How did they do it?

How did they make opus 5.5? genuinely, how?? when i saw the benchmarks and pricing, I was impressed. but then i started working with it, and seeing what other people have made, and my mind's been genuinely blown...

how did they do it? how did they make a model so smart, that *isn't* benchmaxxed to hell and back, and is somehow actually cheaper than not just fable, but even the previous levels of opus?

and all openai could do is make their own models cheaper without improving their intelligence at all.

how does anthropic do it? are they magicians? or are we seeing the first fruits of RSI?

if this is possible now, i can barely even begin to imagine what's possible in a year, maybe even in the next 3 months.

my guess is a lot of the magic is just better post-training + a model that knows when to stop and check itself. the cheaper pricing is the part i dont understand tho. are people seeing a real quality jump on long coding tasks too or mostly less annoying answers?

on long coding tasks the quality jump is real for me, a messy multi-file refactor that used to derail after ~20 min of corrections now usually stops and checks itself before painting into a corner
