WorldBox gives agents spatial memory in Minecraft: Opus 5.5 progress up 133%, Astra +50%

Enactra launched WorldBox, a sandbox that gives agents spatial memory — tracking where they've explored, where resources are, and what they can return to.
In Minecraft tests, Opus 5.5 saw its progress leap 133% and GPT-6 Astra gained 50% once equipped with world memory; the demo shows Opus turning that memory into a diamond pickaxe. The author frames it as a first step toward infrastructure rebuilt for Physical RSI, with more to come.
