Enigma

So we did a thing

World models could lead to a significant leap for open-ended learning and embodied AGI. Multiplayer brings another dimension. Great work!!

Multiplayer in an AI simulated world. This has become reality faster than expected. It's absolutely fantastic what is possible here.

Cool work by @enigma_ai . Open-sourced Multiverse, the first AI multiplayer world model, built for under $1.5K. It simulates real-time shared environments using a novel architecture combining diffusion and joint-action modeling. Everything—code, data, weights, training pipeline—is publicly released. → Multiverse extends traditional single-player world models by combining both players’ inputs into a single joint action embedding and processes both frames as one unified entity using channel-axis stacking for consistency. → Uses a U-Net-based diffusion model for simultaneous dual-frame generation, ensuring both players see coherent and causally consistent outcomes in real-time. → Captures vehicle kinematics and low-speed relative motion using a clever sparse frame sampling strategy—latest 4 frames + every 4th frame over the next 4—spanning 0.666 seconds of context. → Trained on modified Gran Turismo 4, with custom 1-v-1 mode using replay footage and computer vision to extract control inputs from HUD indicators. → B-Spec mode enabled fully autonomous data generation, massively scaling the dataset without human input logging. → Achieved 15-second autoregressive prediction with curriculum learning and memory-efficient paged frame loading to manage GPU VRAM constraints.

Gran Turismo 4 has been used to train a new AI research project called "Multiverse" by @enigma_ai. The team of AI researchers (and Gran Turismo fans) have developed a new technique for creating AI-generated worlds for multiplayer games: gtplanet.net/gran-turismo-4…

This is the coolest dataset I've seen on @huggingface today: action labels of 1v1 races in Gran Turismo 4 to train a multiplayer world model! Great stuff by @enigma_ai!

Multiplayer: ✅

Enigma labs dropped Multiverse on Hugging Face AI Multiplayer World Model Multiplayer was the missing piece in AI-generated worlds — now it’s here. Players can interact and shape a shared AI-simulated world, in real-time. Training and research cost < $1.5K. Run it on your own PC.

Introducing Multiverse: the first AI-generated multiplayer game. Multiplayer was the missing piece in AI-generated worlds — now it’s here. Players can interact and shape a shared AI-simulated world, in real-time. Training and research cost < $1.5K. Run it on your own PC. We @enigma_ai are open-sourcing everything: code, data, weights, architecture, and research. Here’s a closer look (and how it works!):
