OpenDreamer Live Demo
A live, browser-based demo hosted on Reactor's runtime. The interface clearly toggles between two labeled modes: "Game" — the real, unmodified Minecraft environment — and "Dream", where OpenDreamer generates every frame in real time in response to your keyboard and mouse input. No account is required; entry involves a short capacity queue ("join the line"), and each session is time-limited.

by Reactor
An open reproduction of DeepMind's Dreamer4 world-model pipeline, built by researchers Diego Marti Monso, Francesco Sacco and Edward Hu with infrastructure support from Reactor. A 1.6B-parameter dynamics model (30 block-causal transformer layers, JAX/Flax NNX) trained on Minecraft/VPT-style gameplay data, generating real-time interactive video frames from live keyboard and mouse input.
