Lu and colleagues: DPM-Solver++ guided diffusion sampling

What changed

Used data-prediction parameterization, thresholding and multistep updates to improve stability of fast diffusion sampling with strong guidance.

Scientific scope

Used data-prediction parameterization, thresholding and multistep updates to improve stability of fast diffusion sampling with strong guidance. Guidance strength, model parameterization and thresholding applicability matter. Pinned v1 excludes later SDE-solver extensions added to the report.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Guidance strength, model parameterization and thresholding applicability matter. Pinned v1 excludes later SDE-solver extensions added to the report.
