Quick Comparison

Eight checkpoints, four columns that matter. Every model here is a full checkpoint file — no LoRAs, no embeddings. If you want LoRAs instead, see the Flux NSFW LoRA list.

Model Reviews VRAM (lowest format) Updated Best For Pick
Fluxed Up 8.0 542 8 GB (Q4 GGUF) Mar 2026 Overall NSFW quality
Persephone 2.0 182 8 GB+ (GGUF) Jan 2026 NSFW + SFW dual use
Flux Unchained 1,010 12 GB+ 2024 Proven, stable output
Fluxmania 5-star 8 GB (FP8) 2025 Artistic nudes/portraits
MS Flux V3 429 8 GB (Q4_K_S) Jul 2025 Softcore / tasteful nudity
NSFW Master Flux 8 GB+ (FP8) Zero-config pre-merged
CHROMA 8 GB (Q4_K_S) Active Commercial use (Apache 2.0)
Flux NSFW UNLOCKED 12 GB+ 2026 Newer entrant

Every Flux Dev checkpoint requires separate VAE (ae.safetensors, 335 MB) and text encoders (clip_l 246 MB + T5-XXL 4.89–9.79 GB). CHROMA is the exception — it's Schnell-based, not Dev.

The Checkpoints

1. Fluxed Up 8.0

The default. 542 reviews, v8.0 shipped March 21, 2026, and it's the only checkpoint with five format tiers.

Architecture VRAM Best For
Flux.1 D 12 GB+ FP16, 8 GB Q4 GGUF General NSFW — photorealistic female subjects

Fluxed Up leads on every measurable axis: review count (542), engagement (99.3k likes, 8.6M downloads), and update cadence (eight major versions since launch). File sizes range from 22.17 GB (BF16/FP16) down to 6.34 GB (Q4 GGUF), so it works on GPUs from RTX 3060 12 GB to RTX 4060 8 GB with GGUF. The weakness is scope — it's trained on female subjects and doesn't prioritize male anatomy. No VAE or CLIP baked in.

Recommended sampler: DPM++ 2M, beta scheduler, 20–30 steps.

2. Persephone 2.0

One model for NSFW and SFW. Saves you from swapping checkpoints between projects.

Architecture VRAM Best For
Flux.1 D (merge) 12 GB+ FP16, GGUF available Dual-purpose NSFW/SFW generation

Persephone handles clothed portraits and explicit content from the same file — 1.1M downloads and 182 reviews back that up. FP16 is 22.17 GB, with compressed GGUF and FP8 options. Some users report OOM errors even on 32 GB cards, so monitor VRAM during generation. Updated January 2026.

3. Flux Unchained by SCG

Highest review count on any Flux NSFW checkpoint: 1,010 reviews, overwhelmingly positive.

Architecture VRAM Best For
Flux.1 D 12 GB+ Stable, proven NSFW output

Trained on ~5,000 images (80% photography, 20% AI/illustrative) including ~1,500 explicit nudes. SCG tested 120 checkpoint variants before releasing this one. The tradeoff: it hasn't been updated since 2024. Multiple step variants exist — full, 8-step hybrid (HyFU), and 4-step schnell (SchnFU). Still works. Don't expect updates.

4. Fluxmania (Kreamania)

Best image quality of any checkpoint on this list. Less explicit, more artistic.

Architecture VRAM Best For
Flux.1 D 12 GB+ FP16, 8 GB FP8 Artistic nudes, photorealistic portraits

Fluxmania produces exceptional lighting, skin texture, and composition — it's built for portraits and artistic nudes, not hard NSFW. Three file options: FP16 (22.07 GB), FP8 (11.16 GB), and FP8 with baked-in VAE + CLIP (15.91 GB). That last one is rare — most Flux checkpoints make you download VAE and CLIP separately. 50k+ downloads.

Recommended sampler: DPM++ 2M, sgm_uniform scheduler (not beta), 20–30 steps, guidance 3.5.

5. MS Flux SFW/NSFW V3

Nudity without explicit content. The softcore option for users who don't need full NSFW.

Architecture VRAM Best For
Flux.1 D (merge) 12 GB+, 8 GB Q4_K_S Tasteful nudity, anatomical rendering

MS Flux V3 deliberately avoids pornographic output — it's built for nudity that stays in "artistic" territory. 429 reviews, 16.06 GB standard (smaller than most Flux checkpoints). GGUF Q4_K_S version brings it under 8 GB VRAM. Not updated since July 2025.

Recommended sampler: Euler or Simple, CFG 3.5, 15+ steps.

6. NSFW Master Flux

Pre-merged LoRA checkpoint. Drop it in, generate. No LoRA configuration needed.

Architecture VRAM Best For
Flux.1 D (LoRA merged) 12 GB+ FP16, 8 GB+ FP8 Zero-config NSFW

This takes one of the most popular NSFW LoRAs and bakes it directly into a Flux dev checkpoint. FP16 (~22 GB) or FP8 (~11 GB). The tradeoff: you can't adjust LoRA weight after the fact, and community data on this specific checkpoint version is thin compared to standalone models. If you don't want to deal with LoRA loaders at all, this is the shortcut.

7. CHROMA

The only commercially-licensed Flux NSFW option. Apache 2.0. Schnell-based — 1–4 steps, not 20–30.

Architecture VRAM Best For
Flux.1 Schnell (8.9B) 12 GB FP8, 8 GB Q4_K_S Commercial use, fast inference

CHROMA is a different beast. It's forked from Schnell (not Dev), uncensored at the training level, and licensed Apache 2.0 — the only checkpoint on this list you can use commercially. Inference runs in 1–4 steps vs 20–30 for Dev-based checkpoints. Trained on ~5M curated images. Multiple versions: v.48 detail-calibrated, v.46 flash, HD, base. Supports existing Flux LoRAs.

The tradeoff: different sampler settings (euler/simple, not DPM++ 2M), smaller CivitAI ecosystem, and broad training data (anime, photography, furry art) means it's less focused than purpose-built NSFW checkpoints.

8. Flux NSFW UNLOCKED V2.0

2026 entrant. Limited public data — listed for completeness.

Architecture VRAM Best For
Flux.1 D 12 GB+

This checkpoint appeared in 2026 but most stats are gated behind CivitAI's sensitive content login. We can't rank it confidently without verified review counts and download numbers. Check the CivitAI page directly if you're interested.


Format and VRAM Guide

Every Flux checkpoint ships in multiple formats. Here's which to download based on your GPU:

Your GPU VRAM Recommended Format File Size Quality vs FP16
RTX 4090 / A6000 24 GB BF16 or FP16 ~22 GB 100%
RTX 4070 Ti / 3060 12 GB 12 GB FP8 ~11 GB 98–99%
RTX 4060 / 3060 8 GB 8 GB GGUF Q4 or Q4_K_S ~6 GB 90–93%

You'll also need the T5-XXL text encoder alongside the model. FP16 T5 is 9.79 GB; FP8 T5 is 4.89 GB; GGUF Q5 T5 is 3.29 GB. On 8 GB GPUs, use the GGUF T5.

Place checkpoints in models/checkpoints/ (ComfyUI) or models/Stable-diffusion/ (Forge). Or skip file management with LocalForge AI — it ships with Forge pre-configured.

FAQ

What is the best Flux NSFW checkpoint right now? +
Fluxed Up 8.0. It has 542 reviews, 99.3k likes, and v8.0 shipped March 2026. Available in five formats from 22.17 GB (BF16) down to 6.34 GB (Q4 GGUF).
What's the difference between FP16, FP8, and GGUF for Flux checkpoints? +
FP16 is full precision (~22 GB, 12 GB+ VRAM). FP8 halves file size to ~11 GB with 98-99% quality. GGUF is a quantized format that goes as low as 6.34 GB (Q4) for 8 GB GPUs — needs the ComfyUI GGUF node or Forge.
Which Flux NSFW checkpoint runs on an 8 GB GPU? +
Fluxed Up Q4 GGUF (6.34 GB), CHROMA Q4_K_S, and MS Flux Q4_K_S all fit in 8 GB VRAM. You'll also need a compressed T5-XXL text encoder (GGUF Q5 at 3.29 GB) to stay under budget.
Do Flux NSFW checkpoints include VAE and CLIP? +
Almost none do. You need to download ae.safetensors (335 MB), clip_l (246 MB), and T5-XXL (4.89-9.79 GB) separately. The one exception is Fluxmania's FP8 bundle (15.91 GB) which bakes in VAE and CLIP.
Is there a Flux NSFW checkpoint for male subjects? +
Most checkpoints, including Fluxed Up, are trained primarily on female subjects. For male nudity, your best option is pairing a base checkpoint with the Lustly.ai Uncensored LoRA, which handles both male and female subjects.
Can I use Flux NSFW checkpoints commercially? +
Only CHROMA (Apache 2.0 license). Every other checkpoint on this list inherits the FLUX.1 [dev] Non-Commercial License from Black Forest Labs. If you need commercial rights, CHROMA is the only path.
