| Sampler | Speed | Accuracy | Steps Needed | Best Use Cases | Notes / Behavior |
|---|---|---|---|---|---|
| DDPM | Slowest | Stable | 200–1000 | Reference, research | Original diffusion sampler; rarely used now |
| DDIM | Fast | Medium | 20–100 | General-purpose, quick tests | Deterministic shortcut; good default |
| Euler | Fast | Medium-High | 20–40 | High-contrast images, consistent detail | One of the simplest and cleanest samplers |
| Euler a (Ancestral) | Fast | Stylized / soft | 20–40 | Artistic styles, more randomness | Adds controlled noise for more creativity |
| Heun | Medium | Medium-High | 20–50 | Balanced structure and detail | More stable than Euler in some cases |
| DPM++ | Fast | High | 15–30 | High-detail still images | Can flicker in video unless tuned |
| DDPMSolver | Very Fast | Very High | 5–30 | Images + video, stable consistency | Excellent at low steps; not the same as DPM++ |
| DEIS | Medium-Fast | High | 10–50 | Smooth video transitions | Great for temporal consistency |
| UniPC | Fast | High | 8–30 | Stable image or video sampling | Predictor-corrector; excels at low steps |
| CausVid | Medium | High (temporal) | 15–40 | Video generation with motion coherence | Causal progression reduces flicker |
| ODE (Euler/Heun/RK) | Medium-Slow | Very High | 20–60 | Scientific, precise sampling | Deterministic and mathematically stable |
| SDE samplers | Medium | High | 20–60 | Complex motion patterns | Introduce stochastic noise for variety |
