Unique: Implements two-stage generation with separate refiner model that continues from base model latents, enabling optional quality improvement without increasing base model size; supports flexible composition of base and refiner for quality/latency tradeoff

vs others: More modular than single-stage models (refiner is optional); enables quality improvement without retraining base model; comparable to other two-stage approaches but with better integration and documentation
