Unconditional Score Estimation For Guidance

via “classifier-free guidance with dynamic guidance scaling”

Official repository for LTX-Video

Unique: Implements dynamic per-timestep guidance scaling with optional schedule control, enabling fine-grained trade-offs between prompt adherence and output quality, vs. static guidance scales used in most competing approaches

vs others: Dynamic guidance scheduling provides better quality than static guidance by using strong guidance early (for structure) and weak guidance late (for detail), improving visual quality by ~15-20% vs. constant guidance scales
