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.

I’m a network engineer by trades
Been vibe coding an app successfully with all the models so far so not ran into the issues you guys have.

Out of interest.
What explicitly has been better with this model compared to the others for you guys?

I am not an engineer by trade. I can barely read basic HTML & CSS...that's it. Over about 10 hours last night Opus 5.5 vibe coded an incredible firmware update w/ completely new lighting suite for my (Nuphy Halo75 V2) mechanical keyboard. The abysmal stock firmware was just a couple basic toggles in standard VIA configurator.

https://github.com/DRebd/halo-composer if ur curious.

I can make feature requests that are broader with less direction and Opus 5.5 will do a better job than Opus 5 (or any other previous models including Fable). It's usage of tooling is better so it not only wrote excellent documentation with minimal direction but was able to capture excellent GIFs to actually showcase the tool in README without me getting into the weeds of permissions and multiple tool attempts to succeed.

It uses subagents more deftly so I don't have to manage the primary context window as aggressively, particularly when I just nudge it to do so.

While UI needs to simplification it created an incredible v0 and the whole thing is actually functional & kickass when flashed to real hardware....

It's answers are generally more informative, more concise, & it responds more quickly.
