A developer asked frontier models to build FLATROOM V3, a genuinely novel offline HTML three.js game with dual realities and folding rooms. Opus prudently proposed cutting scope, admitting in its reasoning that the task is 'essentially impossible to fully implement' while planning a strong playable demo; DeepSeek melted down in confusion; Astra assumed games are slop and didn't try — though it's the only one fit to write the relevant math. Novel tasks expose each model's character.
