Opus 5 fully procedural 3D world experiment wraps up
A developer closed out an Opus 5 experiment building an explorable, zero-asset procedural world of terrain, rivers and a golem, and is moving on to Opus 5.5.
Closing out my Opus 5 experiment. The goal: the most graphically complex fully procedural world I could get to, explorable, with zero downloaded assets. Terrain, trees, rocks, the river, the golem, the weapon in your hand: all code. Verdict: the goal is met, more or less. It could keep getting better, but I don't see the point. Opus 5.5 is out and already giving more interesting results. That's the next post. The bill: • 72 Claude Code sessions, 79h of active agent time • 9,963 requests, 2.53B tokens, 98.35% of them cache reads • ~$1,738 at API pricing • ~87% of requests on Opus 5; the tail already ran on 5.5 and Fable Opus 5 → 5.5 🧵 next #threejs #tsl
