The quoted post introduces Netherite, a Minecraft 1.11.2 reimplementation written from scratch in C and CUDA and bit-verified against the original game.
It highlights an unusual training setup:
- a single trained agent plays in the environment
- the renderer is also the training target
- 7,200 live worlds run in lockstep on one GPU
The post is essentially a showcase of extreme simulation efficiency for agent training, more than a product announcement.
