Samplers (How Noise Is Removed)
These are the algorithms that guide the diffusion process. Samplers shape how noise is removed. crisp vs. soft, deterministic vs. random.
Euler (Euler normal) – Fast, balanced, but can be less detailed.
Euler a (Euler Ancestral) – Adds randomness; sharper and more varied.
DDIM – Deterministic, fast, consistent, slightly blurrier.
LMS/PLMS (Multistep)
LMS – Sharp results, slower convergence, great for fine detail.
PLMS – Faster than LMS; good quality at lower steps.
DPM & DPM++ Series (Probabilistic)
DPM (original) – Basic probabilistic sampler.
DPM++ 2M – Strong balance: detail, speed, and performance.
DPM++ 2M SDE – Stochastic variant; more artistic, soft realism.
DPM++ 2M Karras – Excellent for polished portraits/anime.
DPM++ 3M SDE – Ultra-detail; slower but high-precision realism.
DPM++ SDE – Fully stochastic; ideal for creative/fantasy art.
DPM++ 2S Ancestral – Stylized realism—texture-rich.
DPM++ 2S – Deterministic version—nice detail vs speed.
DPM-Solver – Fast, minimal steps, decent quality.
Ancestral Variants(widely used)
Euler a (above), DPM2 a, etc. — introduce ancestral noise for creative outputs.
Other Legacy/Fine-Tuned(older or less commonly used samplers)
UniPC BH2 – Sharp stylized lighting and detail.
Euler DMA/SMEA/DY – Tweaked Euler variants balancing stability & detail.
IPNDM, DEIS, Unipc_BH2, and other older samplers – occasionally useful for tests or specific effects.
Common or quick picks
Euler a - Quick, crisp/creative drafts
DPM++ 2M Karras - Polished portraits/anime
DPM++ SDE or 3M SDE - Soft realism, fantasy, ultra-real

Schedulers (When Noise Strength Changes)
Schedulers manage the noise reduction schedule across sampling steps. Schedulers define the denoising trajectory. smooth, textured, or fast.
1. Karras – Smooth transitions; ideal for high-quality and anime styles.
2. Linear_Quadratic – Balanced, a mix of sharpness and smoothness.
3. Simple – Fastest schedule; minimal fuss, efficient generation.
4. DDIM_Uniform – Uniform steps; fast with acceptable quality.
5. SGM_Uniform – Similar to DDIM_Uniform; slightly softer results.
6. Exponential – Strong early denoise, lots of texture; artistic flair.
7. Beta – Adds variability/texture; popular in templates like “Chroma” .
8. Normal – Balanced denoising across steps; safe and reliable for most cases
Common or quick picks
Karras - Portraits, clarity, smooth transitions
Linear_Quadratic - Balanced gradient/detail
Simple - Fastest choice
Exponential/Beta - Artistic and expressive output

TIPS
Creative vs. precise: Use ancestral or stochastic samplers (Euler a, DPM++ SDE) with artistic schedulers (Exponential, Beta) for more varied and expressive images.
Portraits/realism: Choose multistep or DPM++ with smooth schedulers (Karras, Linear_Quadratic) for clarity and fidelity.
Speed-first: Go with PLMS, DDIM, Simple/SGM for fast drafts or prototypes

Try 20–30 steps for most samplers; use 40–50 for ultra-detailed styles like DPM++ 3M SDE.
Set CFG Scale:
6–8 – creative and loose
9–11 – prompt fidelity with balance
12–15 – strict adherence but may overfit

COMBOS FOR SPECIFIC BASE MODELS
SDXL‐based models (e.g., SDXL base, Pony, Illustrious, Noob AI)
Sampler: Euler a (Euler Ancestral)
Scheduler: Karras
This pairing is a go-to default for SDXL finetunes. recommend “Euler A + Karras” for anime or crisp styles, while DPM++ 3M SDE + Karras is often preferred for photorealism.
Quick presets
Pony SDXL: Euler a + Karras, 30 steps, CFG 4–6
Illustrious & Noob AI: They work similarly – Euler a + Karras gives clean, artistically faithful anime-style outcomes
Photoreal SDXL: Swap to DPM++ 3M SDE + Karras, CFG ~4 for ultra-realism
•°•
Flux (e.g., FLUX.1-dev, Flux.1 Schnell, Hyper Flux)
Sampler: Euler (no-ancestral)
Scheduler: Simple or beta produces clean Flux images
Steps: ~20 for FLUX.1-dev, 2–4 for Schnell low‑step mode
CFG: 1.0 (turn off strong guidance)
For Schnell: Euler + discrete at 2–4 steps, CFG=1 also found DEIS + DDIM_uniform or LCM + SGM_uniform useful for photoreal-style Flux workflows.
Quick presets
Flux.1‑dev: Euler + Simple, 20 steps, CFG 1
Flux‑Schnell: Euler + Discrete, 3 steps, CFG 1
Flux‑Hyper or Pro: Start with Euler + Simple/Beta, ~20 steps, CFG 1
•°•
Pony
Built on SDXL and popular for anime art
Euler a + Karras, Clip Skip –2, 30–40 steps, CFG ~6
Good for colorful anime renders
•°•
Noob AI
Same strategy as Pony and Illustrious
Euler a + Karras, ~30 steps, CFG 4–6 is the standard
•°•
Illustrious
Also SDXL‑based and anime focused
Euler a + Karras is recommended for best quality anime-style outputs, though DPM++ SDE variants also work if you want softer, more detailed realism
•°•°•°•°•°•°•°•°•°•°•°•

•°•°•°•°•°•°•°•°•°•°•°•
Flux models prefer CFG=1, unlike SDXL which uses higher values.
Clip Skip –2 boosts image quality on SDXL anime models (Pony, Illustrious) .
Swap to DPM++ 3M SDE + Karras for ultra-real outputs with SDXL.
For creative atmospheres, pair Euler with Beta rather than Karras.

DO NOT take my words as law for this, you can always mix and match to your liking to find YOUR preferred setting. This is just whats common/recommended.
I may periodically make changes to this if needed. I'm still trying to find how I should organize or word certain things. Tips are welcome
