DreamX-Creator: Democratizing Native Audio-Video Generation at 2K Resolution

arXiv 2026 14.9 method, system

TLDR

DreamX-Creator 1.0 is a compact 7B system for native joint audio-video generation from text and first frame, with cross-modal attention, progressive training, RL post-training, and 2K refinement.

Reasoning

The paper presents a technical system for synchronized audio-video generation with detailed architecture and training contributions. Its strengths include native joint generation and high-resolution refinement, but the abstract does not connect the work to world models, world simulators, or world dynamics prediction.
