This working implementation of text-to-3D (powered by Stable Diffusion) didn’t take six months, like Simon predicted it would. Although I will concede that it’s not a 3D environment that can then go into in a game engine, but I’m sure that’s just a few more weeks away this point.

From the readme:

This project is a work-in-progress, and contains lots of differences from the paper. Also, many features are still not implemented now. The current generation quality cannot match the results from the original paper, and many prompts still fail badly!
