This model is a fine-tuned version of Qwen3-4B-Instruct-2507, optimized specifically to rewrite AI-generated text into a more natural, human-like style. It was trained to reduce the "robotic" tone often found in LLM outputs while maintaining the original meaning and factual accuracy.

Base Model: unsloth/Qwen3-4B-Instruct-2507 (merged from unsloth/Qwen3-4B-Instruct-2507-bnb-4bit)
Fine-tuned by: Heatw4ve
Fine-tuning Tool: Unsloth
Quantization format: GGUF (Quantized to Q4_K_M)
Training framework: Unsloth (LoRA-based SFT)
Language: English
Intended usage: Local inference, research, and experimentation

Training Details

The model was fine-tuned using LoRA (Low-Rank Adaptation) on a custom dataset of 28,000+ pairs of AI vs. Human-rewritten text.

Training Configuration

The model was fine-tuned with the following parameters:

Epochs: 2
Learning Rate: 5e-5
Optimizer: AdamW 8-bit
LR Scheduler: Cosine
Warmup Steps: 100
Context Length: 512 tokens
LoRA Config: - Rank (r): 64
- Alpha: 128
- Target Modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
Effective Batch Size: 128 (32 per device * 4 grad accumulation)

Usage

This is a GGUF version, compatible with LM Studio, Ollama, and llama.cpp. Works best with inputs of length 15-150 words.

System Prompt

To achieve the intended rewriting style, use the following system prompt:

You are a helpful assistant that rewrites AI-toned text into natural, human-like writing.

User Prompt Format

text

Rewrite the following text to sound like a real human wrote it:

William Shakespeare, the master of human insight, gifted us with a timeless observation that cuts to the heart of intellect and humility: "The fool doth think he is wise, but the wise man knows himself to be a fool." Uttered by the character Touchstone in As You Like It, this seemingly paradoxical statement is far more than a witty quip; it's a profound commentary on self-awareness, the nature of true wisdom, and the perpetual quest for knowledge.
