Welcome to the world of artificial intelligence, where we delve into how we can tailor large language models (LLMs) to specific domains like finance, law, and biomedicine. This guide will walk you through the process of utilizing the AdaptLLM framework and give you insights into troubleshooting common issues.

Understanding the Framework

At the heart of our adaptation mechanism is the LLaMA-2-Chat-7B model. Think of it as a large sponge soaked with general knowledge about various topics. However, to specialize in a domain—like finance—it needs to be squeezed out and soaked again with specific financial knowledge, allowing it to absorb pertinent information from the domain-specific texts.

We achieve this by transforming vast pre-training datasets into a reading comprehension format, which boosts the model’s ability to respond accurately to domain-specific queries. This method shows that even with smaller models, you can compete with much larger specialized models.

How to Use the Finance-Chat Model

Here’s a step-by-step guide on how to implement and interact with the finance chat model:

1. Install the Required Libraries: Make sure you have the Transformers library installed in your Python environment.
2. Load the Model: Use the following Python code to load the finance chat model.

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("AdaptLLM/finance-chat")
tokenizer = AutoTokenizer.from_pretrained("AdaptLLM/finance-chat")

3. Prepare Your Input: Structure your user input clearly to get the best response. Here’s how to set up your interaction:

user_input = "Use this fact to answer the question: What are the trading symbols for 3M Corporation?"

4. Create a Prompt: Follow the LLaMA-2-Chat style prompt.

# Define system prompt
our_system_prompt = """You are a helpful financial assistant. Always provide accurate and concise financial data."""

# Combine to create chat input
prompt = f"[INST] SYS{our_system_prompt}SYS\n\nuser_input [INST]"
inputs = tokenizer(prompt, return_tensors='pt', add_special_tokens=False).input_ids.to(model.device)

5. Get the Response: Generate a response using the model.

outputs = model.generate(input_ids=inputs, max_length=4096)[0]
answer_start = int(inputs.shape[-1])
pred = tokenizer.decode(outputs[answer_start:], skip_special_tokens=True)
print(f"### Assistant Output:\n{pred}")

Troubleshooting Common Issues

While adapting LLMs is a fascinating journey, you might run into some bumps along the way. Here are a few common issues and how to fix them:

• Model Not Loading: Ensure that you have a stable internet connection and that the model name is typed correctly.
• Unexpected Outputs: This can occur due to poorly formatted prompts. Ensure your user input is clear and structured.
• Performance Drops: If the model seems to provide irrelevant information, consider adjusting the pre-training format or reviewing the chosen domain-specific texts.
