This model is a fine-tuned version of deepseek-ai/DeepSeek-R1-Distill-Qwen-7B that has been specialized for high-quality paraphrase generation. It was trained using LoRA (Low-Rank Adaptation) and then merged back into the base model for efficient inference.

Model Details

Base Model: deepseek-ai/DeepSeek-R1-Distill-Qwen-7B
Task: Paraphrase Generation
Training Method: LoRA fine-tuning with r=16, alpha=32
Training Data: Multi-domain text from literary works, technical documentation, academic papers, and articles, plus the Quora paraphrase dataset

Performance

This model outperforms standard paraphrasing models like BART and T5 on key metrics:

Semantic Preservation (BERTScore): 0.952 - Excellent
Lexical Diversity (BLEU Diversity): 0.513 - Acceptable
Character-level Changes (Edit Distance): 0.344 - Acceptable
Structural Variation (Syntactic Diversity): 0.147 - Moderate
Overall Balance (Harmonic Score): 0.468 - Acceptable

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "PeterAM4/deepseek-paraphrase"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

text = "Learn Once, Write Anywhere: We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code."

prompt = f"<｜begin▁of▁sentence｜><｜User｜>Paraphrase the following text while preserving its meaning but changing the wording and structure: {text}<｜Assistant｜><think>\nLet me analyze this text and find ways to rephrase it while keeping the same meaning.\nI need to use different vocabulary and structure.\n</think>\n\n"

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=200,
    temperature=0.7,
    top_p=0.95,
    do_sample=True
)

paraphrase = tokenizer.decode(outputs[0], skip_special_tokens=True).replace(prompt, "")
print(paraphrase)

Limitations

Very technical or domain-specific terminology may not be paraphrased optimally
Always review paraphrases for factual accuracy and meaning preservation
