WorldBox spatial memory boosts Opus 5.5 Minecraft progress 133% and GPT-6 Astra 50%
Lianhuiq · x · 2026-10-09
Enactra introduced WorldBox, a Minecraft sandbox that gives agents spatial memory of where they've explored, where resources are, and what they can return to. With this memory, Opus 5.5's progress jumped 133% and GPT-6 Astra 50%, with Opus turning the memory into crafting a diamond pickaxe. Side-by-side races with and without WorldBox are in the thread, framed as a showcase of world models enabling real-time physical intelligence.
