OUR NOTEAn explorable 3D AI data center where overloading a rack throttles its GPUs and heat plumes rise out the roof; built in one shot over 1h53m for $38.99, with 99% of input tokens served from cache.
I asked Opus 5.5 to show me what's inside the buildings it runs in
it came up with this after 1 hour 53 minutes in one shot, $38.99 API cost
https://datacenter.lab.sael.net
it's fully interactive 3D: overload a rack to watch its GPUs throttle, then follow the heat out the roof

The API cost breakdown is the interesting part: 99% of the input was cache hits
Every step resends the whole session. That's 202 calls and 119M input tokens, almost all read from cache at 1/20th of the price. Without caching the same run would have cost about $486
It also read my earlier projects on disk to match the style we'd built in other sessions. So it really is one prompt from idea to finished site, with no follow-ups until I asked to deploy
