Best Flux Uncensored Models

CHROMA (~8.9B params, Apache 2.0, ~1.33k Hugging Face likes on lodestones/Chroma) is the full-weight open-license line. shauray/FLUX-UNCENSORED-merged is the single-from_pretrained merge; Flux-Uncensored-V2 (~687 MB LoRA) strips dev refusals on FLUX.1-dev — base NC license still applies.

The Models

1. CHROMA

Top Pick

Main open-license answer: uncensored by design, ~1.33k HF likes on lodestones/Chroma per Mar 2026 snapshot.

Architecture: Flux-class (~8.9B params, Schnell-class lineage) · VRAM: 12 GB+ typical FP16 class · Best for: Apache 2.0 uncensored base — HF + Diffusers path

2. Flux-Uncensored-V2

EnhanceAI v2 — smaller LoRA than v1 lines; FLUX.1-dev NC still binds the base weights.

Architecture: LoRA → FLUX.1-dev · VRAM: 12 GB+ dev + ~687 MB LoRA · Best for: HF README workflow; strips dev refusals

3. FLUX-UNCENSORED-merged

shauray merge: plug-and-play vs manual LoRA strength tuning.

Architecture: Merged FluxPipeline bundle · VRAM: 12 GB+ class (CPU offload in README examples) · Best for: Single from_pretrained — no separate LoRA files

4. Titanforge V1 FP8

Experimental: creator cites ~35% complete — ~204 reviews on CivitAI listing (verify live).

Architecture: Flux.1 D fine-tune · VRAM: ~15.7 GB FP8 variant (summaries) · Best for: Anatomy-first uncensor experiments

5. Project Gaia Flux1.D (Uncensored)

~3.9k downloads, ~126 ratings cited in roundups — check file matrix before install.

Architecture: Flux.1 D merge + versioned NF4/UNET builds · VRAM: NF4 v2 targets reduced VRAM vs raw dev · Best for: Low-VRAM uncensored-tuned merge

6. aidmaNSFWunlock

130.8k downloads, 1,380 reviews — default LoRA when you stay on stock dev.

Architecture: LoRA for FLUX.1-dev · VRAM: Dev VRAM + minimal LoRA overhead · Best for: Mainstream LoRA path — adult unlock, huge community proof

Why This Matters

Labels lie. "Uncensored" checkpoints and LoRAs are not interchangeable — license, wiring, and VRAM differ by tens of gigabytes. Pick wrong and you burn a weekend on merges that do not match your stack.

Uncensored vs NSFW

Uncensored = broad safety filter removal (refusals, alignment blocks) — not a promise about every niche. NSFW = adult imagery in common usage; many "NSFW" packs target that subset only. Same word, different scope — check the card, not the tag.

Quick Comparison

Model Type License / constraint VRAM (typical) Best for Our pick
CHROMA Full model (Schnell-class lineage) Apache 2.0 on HF card 12 GB+ class Open-license Flux-class base, uncensored-by-design
Flux-Uncensored-V2 LoRA for FLUX.1-dev Dev weights = FLUX.1-dev NC 12 GB+ + ~687 MB LoRA HF-native uncensor on stock dev
FLUX-UNCENSORED-merged Merged HF bundle Dev lineage — NC on base 12 GB+ class One repo, no separate LoRA files
Titanforge V1 FP8 CivitAI checkpoint CivitAI terms ~15.7 GB FP8 cited Anatomy-first experiments
Project Gaia CivitAI merge (incl. NF4 builds) FLUX.1 dev NC NF4 path = lower VRAM vs raw FP16 dev Tight VRAM, uncensored-tuned merge
aidmaNSFWunlock CivitAI LoRA Add-on to dev Dev VRAM + small LoRA 130.8k downloads, 1,380 reviews — mainstream LoRA path

Titanforge's creator rates the project ~35% complete — treat it as a lab checkpoint, not a daily driver. For a managed local stack with less file wrangling, LocalForge AI is built for offline workflows on your hardware.

Verdict

CHROMA wins on license + intent if you need Apache 2.0 weights and a documented ~8.9B Flux-class pipeline. Need one HF download without LoRA wiring? FLUX-UNCENSORED-merged. Already on FLUX.1-dev and want the Hugging Face LoRA path? Flux-Uncensored-V2 (~687 MB). CivitAI scale and tutorials point to aidmaNSFWunlock (130.8k downloads, 1,380 reviews) — adult-focused, not a full "uncensored everything" claim.

What to Do Next

FAQ

What is the difference between uncensored and NSFW for Flux models? +
Uncensored usually means broad safety alignment and refusal removal. NSFW in marketing usually targets adult imagery. A model can be labeled NSFW without covering every non-adult restricted topic — read the card.
What is the best open-license Flux uncensored model? +
CHROMA (`lodestones/Chroma`) ships under Apache 2.0 on the Hugging Face card — ~8.9B params in docs, ~1.33k likes on the repo snapshot (Mar 2026). That is the clearest permissive-weights path vs FLUX.1-dev NC bases.
Is Titanforge ready for production? +
No. The creator documents roughly 35% completeness. CivitAI summaries cite on the order of 204 reviews — treat it as experimental anatomy work, not a default checkpoint.
Do I need a LoRA or a merged checkpoint? +
LoRAs (e.g. Flux-Uncensored-V2 ~687 MB, aidmaNSFWunlock) keep FLUX.1-dev and add behavior. Merges like shauray/FLUX-UNCENSORED-merged bake weights into one bundle. CHROMA is a separate full-model family. Match the path to your UI and license needs.
How much VRAM do uncensored Flux options need? +
Full dev-class runs usually sit in the 12 GB+ range for interactive FP16. Project Gaia markets NF4 builds for reduced VRAM; Titanforge FP8 is cited around 15.7 GB in summaries — always verify the exact file set (VAE/CLIP) on the download page.
Why is aidmaNSFWunlock on an uncensored list? +
It is the highest-download Flux dev LoRA in the CivitAI data we track — 130.8k downloads and 1,380 reviews — so readers comparing LoRA scale see the mainstream NSFW path alongside broader uncensor merges.
