LLMWriter-8B

LLMWriter-8B is a fine-tuned version of Llama 3.1 8B designed to improve writing quality, instruction following, content generation, and structured response creation.

• Developed by: aldenirsrv
• License: Apache 2.0
• Finetuned from model: unsloth/Llama-3.1-8B

This model was trained using LoRA (Low-Rank Adaptation) with the Unsloth framework and Hugging Face TRL.

This Llama model was trained 2x faster with Unsloth and Hugging Face's TRL library.

Model Description

LLMWriter-8B is focused on:

• Content creation
• Technical writing
• Documentation generation
• Blog writing
• Social media content
• Instruction following
• Writing assistance
• General-purpose text generation

The model was trained on a curated instruction-following dataset containing over 10,000 examples.

Usage

vLLM

vllm serve aldenirsrv/LLMWriter-8B \
  --host 0.0.0.0 \
  --port 8888

Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "aldenirsrv/LLMWriter-8B"

tokenizer = AutoTokenizer.from_pretrained(model_name)

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    device_map="auto"
)

prompt = "Write a blog post introduction about AI governance."

inputs = tokenizer(
    prompt,
    return_tensors="pt"
).to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=300,
    temperature=0.7
)

print(
    tokenizer.decode(
        outputs[0],
        skip_special_tokens=True
    )
)

OpenAI-Compatible API (vLLM)

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:8888/v1",
    api_key="dummy"
)

response = client.chat.completions.create(
    model="aldenirsrv/LLMWriter-8B",
    messages=[
        {
            "role": "user",
            "content": "Write a blog post about AI governance."
        }
    ]
)

print(response.choices[0].message.content)

Limitations

• The model may generate inaccurate information.
• Outputs should be reviewed before publication.
• Not intended for legal, medical, or financial advice.
• Performance depends on prompt quality and task complexity.
• The model has not been evaluated on standardized benchmark suites.

Future Work

Planned improvements include:

• Human preference evaluation
• Benchmark comparisons against the base model
• Additional instruction tuning
• Domain-specific fine-tuning
• Expanded evaluation datasets
• Quantized deployment variants
