Mistral-7B-Telco

Model Description

This model, "Mistral-7B-Telco", is a fine-tuned version of the mistralai/Mistral-7B-Instruct-v0.2, specifically tailored for the Telco domain. It is optimized to answer questions and assist users with various Telco-related procedures. It has been trained using hybrid synthetic data generated using our NLP/NLG technology and our automated Data Labeling (DAL) tools.

The goal of this model is to show that a generic verticalized model makes customization for a final use case much easier. An overview of this approach can be found at: From General-Purpose LLMs to Verticalized Enterprise Models

Intended Use

Recommended applications: This model is designed to be used as the first step in Bitext’s two-step approach to LLM fine-tuning for the creation of chatbots, virtual assistants and copilots for the Telco domain, providing customers with fast and accurate answers about their needs.
Out-of-scope: This model is not suited for non-telco related questions and should not be used for providing health, legal, or critical safety advice.

Usage Example

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

device = 'cuda' if torch.cuda.is_available() else 'cpu'

model = AutoModelForCausalLM.from_pretrained("bitext/Mistral-7B-Telco")
tokenizer = AutoTokenizer.from_pretrained("bitext/Mistral-7B-Telco")

messages = [
    {"role": "system", "content": "You are an expert in customer support for Telco."},
    {"role": "user", "content": "I would like to deactivate a cell phone, where could I do it?"},
]

encoded = tokenizer.apply_chat_template(messages, return_tensors="pt")

model_inputs = encoded.to(device)
model.to(device)

generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True)
decoded = tokenizer.batch_decode(generated_ids)
print(decoded[0])

Model Architecture

This model utilizes the MistralForCausalLM architecture with a LlamaTokenizer, ensuring it retains the foundational capabilities of the base model while being specifically enhanced for telco-related interactions.

Training Data

The model was fine-tuned on the Bitext Telco Dataset comprising various telco-related intents, including: set_usage_limits, activate_phone, check_mobile_payments, check_signal_coverage, invoices, and more. Totaling 26 intents, and each intent is represented by approximately 1000 examples.

This comprehensive training helps the model address a broad spectrum of telco-related questions effectively. The dataset follows the same structured approach as our dataset published on Hugging Face as bitext/Bitext-customer-support-llm-chatbot-training-dataset, but with a focus on telco.

Limitations and Bias

The model is trained for telco-specific contexts but may underperform in unrelated areas.
Potential biases in the training data could affect the neutrality of the responses; users are encouraged to evaluate responses critically.

Ethical Considerations

It is important to use this technology thoughtfully, ensuring it does not substitute for human judgment where necessary, especially in sensitive situations.
