Astronex-World 1.0: Real-Time Interactive World Model Foundation
TL;DR - Astronex-World 1.0 is an open 5B-parameter video world model that supports controllable, persistent generation from text or images. It matters because it achieves real-time 832Ă—480 video at 24 fps on one NVIDIA L20 GPU while outperforming several larger models on WBench.
- Supports frame-aligned camera trajectories, continuous actions, embodiment IDs, and text events inserted during rollouts.
- Provides bidirectional full-context generation and block-causal generation with cross-block KV caching for persistent streaming.
- Uses PRoPE for camera parameters and a 64-dimensional action stream that modulates every Transformer layer.
- Its five-stage training pipeline runs on two 48 GB L20 GPUs; the final model scores 73.5 on WBench Navi and 70.0 on WBench Full.
