Qwen3-4B Ablated (Uncensored) Text Encoder - GGUF Q4_0

Uncensored/ablated version of Qwen3-4B text encoder in GGUF Q4_0 format for Flux2 Klein 4B models.

Compatible Models

• Flux2 Klein 4B (Distilled & Base)

What This Does

This is an ablated (safety-filtering removed) text encoder that allows Flux2 Klein models to generate NSFW content without prompt censorship.
The base Qwen3-4B text encoder that ships with Flux2 Klein has safety filtering that prevents certain prompts from being processed properly.

Installation

1. Download qwen3-4b-abl-q4_0.gguf
2. Place in ComfyUI/models/text_encoders/ or ComfyUI/models/unet/ (for GGUF loaders)
3. In your workflow, use a GGUF-compatible text encoder loader node
4. Point it to this file instead of the default Qwen3-4B

Prompting Tips

• Use "wearing nothing" instead of "naked/nude" for best nude results
• The model looks for clothing descriptors - even "nothing" counts as one
• Clinical terms like "vagina" don't work better than colloquial terms
• For explicit content beyond nudity, you'll need an NSFW LoRA

Language-Style Mapping Research

I discovered Flux.2 Klein associates languages with specific styles:
Japanese→anime portraits, German→illustrated art, etc.

Limitations

This removes prompt filtering but doesn't add visual knowledge. The base Flux2 Klein models have limited training on explicit content, so:

• ✅ Nudity works well
• ✅ Suggestive poses work
• ❌ Explicit anatomy requires a LoRA
• ❌ Sexual acts require a LoRA
