AWhat changed
Integrated deep-compression autoencoding, linear diffusion attention, a decoder-only text encoder and Flow-DPM sampling/caption-selection choices for efficient high-resolution synthesis. Later Sprint combines continuous-time consistency and latent adversarial distillation with step-adaptive sampling and interactive ControlNet.
Scientific scope
Integrated deep-compression autoencoding, linear diffusion attention, a decoder-only text encoder and Flow-DPM sampling/caption-selection choices for efficient high-resolution synthesis. Later Sprint combines continuous-time consistency and latent adversarial distillation with step-adaptive sampling and interactive ControlNet. Compression, linear attention, diffusion transformers and language encoders are inherited. Delta is the specific combined design and sampler/training study, not invention of linear attention. Original measured resolution/latency comparisons are hardware/configuration dependent. Sprint inherits sCM/LADD/ControlNet. Training-free flow-model conversion does not make the complete distillation training-free. Same family bundled rather than checkpoint counting.
