Business Assistant (Fine-tuned Qwen2.5-1.5B-Instruct)

Model Description

This is a LoRA fine-tuned version of Qwen/Qwen2.5-1.5B-Instruct, specialized to answer Business questions only. It was trained on a synthetic instruction dataset generated using the Groq API (Llama 3.3 70B as the data-generation model), and explicitly trained to politely decline questions outside the Business domain rather than answering them.

Developed by: [Dhwanit Rawat / joyboy5656n]
Model type: Causal decoder-only language model (LoRA fine-tune, merged into base weights)
Language(s): English
License: Apache 2.0
Finetuned from model: Qwen/Qwen2.5-1.5B-Instruct

Uses

Direct Use

Answering Business-related questions: startup strategy, business models, marketing, sales strategy, management, entrepreneurship, HR, negotiation, pricing strategy, competitive analysis, operations, and branding.

Out-of-Scope Use

This model is intentionally trained to refuse questions unrelated to Business (e.g. cooking, medical advice, coding, general trivia). It should not be relied on for domains outside Business, and it is not a substitute for professional financial, legal, or business consulting advice.

How to Get Started with the Model

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "your-hf-username/business-assistant-llm"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForCausalLM.from_pretrained(repo)

messages = [
    {"role": "system", "content": "You are a specialized Business assistant. You ONLY answer questions related to Business. If a question is not about Business, politely decline."},
    {"role": "user", "content": "How do I validate a startup idea before building it?"},
]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
output = model.generate(inputs, max_new_tokens=300)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Training Details

Training Data

A synthetic dataset of instruction-response pairs generated via the Groq API, covering common Business topics, plus a set of refusal examples (~15% of the dataset) pairing off-domain questions with polite declines. Generated under a fixed daily API call budget to stay within Groq's free-tier limits.

Training Procedure

Method: LoRA (Low-Rank Adaptation) fine-tuning, adapters merged into the base model after training
Base model: Qwen2.5-1.5B-Instruct, loaded in 4-bit (NF4) for training
LoRA config: r=16, alpha=32, dropout=0.05, applied to attention and MLP projection layers
Epochs: 3
Effective batch size: 16 (batch size 2 × gradient accumulation 8)
Learning rate: 2e-4
Training regime: fp16 mixed precision

Speeds, Sizes, Times

Trained on a single Kaggle T4 GPU
Dataset size: ~~450 examples (~~380 domain + ~70 refusal examples)

Evaluation

Manual qualitative evaluation was performed by prompting the model with in-domain Business questions and out-of-domain questions (e.g. cooking, sports) to verify it answers the former and declines the latter. No formal benchmark scores are reported.

Bias, Risks, and Limitations

Trained on a small (~450 example) synthetic dataset, so coverage of niche Business subtopics may be limited.
Synthetic training data was generated by another LLM (Llama 3.3 70B via Groq), so any biases or inaccuracies in that model's outputs may be inherited here.
Not intended for use in place of professional business, legal, or financial consulting.

Environmental Impact

Hardware Type: NVIDIA T4 GPU (Kaggle free tier)
Hours used: < 1 hour
Cloud Provider: Kaggle
Compute Region: Unknown

Technical Specifications

Architecture: Qwen2 (Qwen2.5 reuses the Qwen2 architecture class), ~1.5B parameters
Software: transformers, peft, bitsandbytes, datasets, accelerate
