GPT-5.6, Grok 4.5, Claude, and Muse Spark build the same 4 apps

Interesting tests being done but I can't help but think it limits testing innovation in some way given that the requested apps are essentially all clones of others

Similarly, we updated our model arena (52 apps each built by 26 models) to have GPT 5.6 Sol, Terra, and Luna today:

It's really interesting to see the Sol/Terra/Luna apps side-by-side.

I need to add these stats somewhere in the UI, but one interesting take away: Terra took 1/2 as much wall-clock time as Sol, but Luna took more wall-clock time than Sol (by about 23%). It's still much much cheaper, but it seems like Terra is likely a more optimal time/cost balance for most use cases.

The Terra quality is usually nearly as good as Sol, but much faster and cheaper. I do appreciate Sol's design sensibilities (see, for example, the audio sequencer). It's the first model in a while that is clearly distinct on that front. They'd all converged to very similar visuals for a while.

   "This isn't objective." Correct, and we are not pretending it is. We are not handing down a scientific verdict. 

Actually, you are doing rational investigation in a fuzzy probabilistic new/emergent space, with open sharing to the world. I don’t understand why people downplay themselves and put on a pedestal others supposedly serious sciences.

Calculator / Rubik's cube / game of life apps should be very close to 100% identical, right? I don't see the point of asking an AI for one of these when there are dozens (hundreds?) of repos that all have exactly what you want.

My opinion is that spamming HN with two gimmicky "one-shot prompting shootout" marketing pieces in two days does not build confidence about either your technical or marketing expertise.
