If Opus 5.5 was a woman i will never cheat on her

i made this FPP open world game in 7hrs just with Blender and ThreeJS

i think the only limitations there are now is just your imagination

Opus has to be the best model for its weight class and the fact that output stayed consistent since release thank you anthropic
