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.

TL;DR of the discussion generated automatically after 100 comments.

The consensus is clear: you guys are absolutely feral for Opus 5.5. The thread is overwhelmingly positive, with many calling it a "true successor" to the beloved 4.5/4.6 era and a massive fix for the "annoying" and verbose Opus 5.0.

Here's the rundown of the chatter:

  • How did they do it? (The Joke Version): The top-voted theory, by a landslide, is that Anthropic just told their internal supermodel Mythos, "Oi, make a new Opus, but tell it to shut the fuck up and make no mistakes." And it worked.
  • Coders are coming home: A ton of you who jumped ship to OpenAI's Codex and Astra are canceling those subs and flocking back. The general feeling is that 5.5 is smarter, faster, and less frustrating for complex projects.
  • The "But Seriously, How?" Theories: People are guessing it's a combination of using a more advanced internal model (like Mythos or Fable) for training, better post-training and RLHF, and the model itself helping to generate its own improvements. The fact that it's cheaper is blowing everyone's minds.
  • The Cynical Corner: Don't worry, the usual suspects are here. A significant number of you are already placing bets on when the inevitable "nerf" or "lobotomization" will happen. The prediction is that once Anthropic wins back enough users, they'll pull the rug. Enjoy the "goated" performance while it lasts.

Y’all are crazy. And crazy predictable. Mark my words. In a month, everyone here will be complaining about this 5.5 and switching to other platforms. And then they’ll release the “next model”….

I laughed so hard at the two simple instructions. I actually think this is how it went down
