Mistral-7B-Banking-v2

Model Description

"Mistral-7B-Banking-v2" is a specialized adaptation of the mistralai/Mistral-7B-Instruct-v0.2, designed to provide precise answers related to general banking queries. This model is fine-tuned to help users with common banking tasks and inquiries.

Intended Use

• Recommended applications: Ideal for deployment in digital banking platforms where quick and accurate customer service responses are needed. It can be integrated into banking chatbots to assist users with transactions, account information, and other banking services.
• Out-of-scope: This model is not suited for non-banking related questions and should not be used for providing health, legal, or critical safety advice.

Usage Example

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("bitext-llm/Mistral-7B-Banking-v2")
tokenizer = AutoTokenizer.from_pretrained("bitext-llm/Mistral-7B-Banking-v2")

inputs = tokenizer("<s>[INST] How can I transfer money to another account?[/INST]", return_tensors="pt")
outputs = model.generate(inputs['input_ids'], max_length=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

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 banking-related interactions.

Training Data

The model was fine-tuned on a dataset comprising various banking-related intents, including transactions like balance checks, money transfers, loan applications, and more, totaling 89 intents each represented by approximately 1000 examples. This comprehensive training helps the model address a broad spectrum of banking-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 banking.

Training Procedure

Hyperparameters

• Optimizer: AdamW
• Learning Rate: 0.0002 with a cosine learning rate scheduler
• Epochs: 4
• Batch Size: 10
• Gradient Accumulation Steps: 8
• Maximum Sequence Length: 8192 tokens

Environment

• Transformers Version: 4.40.0.dev0
• Framework: PyTorch 2.2.1+cu121
• Tokenizers: Tokenizers 0.15.0

Limitations and Bias

• The model is trained for banking-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 financial situations.
