justinthelaw/Qwen2.5-0.5B-Instruct-Resume-Cover-Letter-SFT

A fine-tuned version of Qwen/Qwen2.5-0.5B-Instruct trained with an SFT + LoRA pipeline to answer questions about Justin's professional background, skills, and experience.

Model Description

This model is designed for browser-based inference using transformers.js. It powers a personal website chatbot that can answer questions about Justin's resume, work experience, education, and skills.

Training Pipeline

The model is trained using SFT (Supervised Fine-Tuning) with LoRA adapters, where factual memorization is enforced via conversation-formatted QA pairs.

ONNX	/onnx/	FP32 + quantized weights for ONNX Runtime/Web inference

Usage

Browser (transformers.js)

import { pipeline } from "@huggingface/transformers";

const generator = await pipeline("text-generation", "justinthelaw/Qwen2.5-0.5B-Instruct-Resume-Cover-Letter-SFT", {
  dtype: "fp32",
});

const output = await generator("What is Justin's background?", {
  max_new_tokens: 256,
});

Python (Transformers)

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("justinthelaw/Qwen2.5-0.5B-Instruct-Resume-Cover-Letter-SFT")
tokenizer = AutoTokenizer.from_pretrained("justinthelaw/Qwen2.5-0.5B-Instruct-Resume-Cover-Letter-SFT")

prompt = "What is Justin's background?"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

This model is intended for:

• Personal website chatbots
• Resume Q&A applications
• Demonstrating fine-tuning techniques for personalized AI assistants

Limitations

• The model is specifically trained on Justin's resume and may not generalize to other topics
• Responses are based on training data and may not reflect real-time information
• Not suitable for general-purpose question answering
