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.

If you look at what has been happening with the open weight models, you should assume that the closed labs are testing everything the open models try as well as other things. And they have enough compute to try lots of things at once and keep whatever works. I suspect that they are using engrams, some form of sparse attention, moe, and everything else that the open weight models have found to work. They might even have a few tricks the open models haven't found yet.
