Opus 5.5 builds a one-take three.js site on the scale of AI compute
On the xhigh setting, Opus 5.5 generated a three.js site in a single continuous camera move from a 2012 GPU die out to the 2026 Stargate campus in Texas, with sourced figures and a 363KB total size.
Opus 5.5 on xhigh just built the entire scale of AI compute as a three.js website, in one continuous camera move. You scroll and it starts inside a single GPU die in 2012, then pulls back through the board, the server, the rack and the data hall, all the way out to the Stargate campus in Texas in 2026. Every number on screen is real, with its source printed right under it. It even corrected my prompt. I asked for a university lab. It found AlexNet was actually trained on two graphics cards in Krizhevsky's bedroom and built that instead. The whole site is 363 KB and runs in the browser. No model files, no textures, every surface generated in code. It checked its own work across 600 tiles and fixed 22 defects on the first pass alone. Three weeks ago Grok 4.6, Fable 5.1 and Opus 5 all fell short on this exact prompt. Only GPT-6 Astra finished it.
