# 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.<br>
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: <br>
Japanese→anime portraits, German→illustrated art, etc.<br>

## 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
