Introducing Meerkat-7B-v1.0, an innovative AI model designed for medical reasoning, surpassing the USMLE passing threshold! In this article, we will walk you through how to implement Meerkat-7B, troubleshoot issues, and provide some useful tips to make your experience as smooth as possible.

Getting Started with Meerkat-7B

Using Meerkat-7B is akin to having a highly intelligent friend at your side, ready to guide you through complex medical problems. Think of it as a virtual assistant that can sift through volumes of medical literature, drawing from extensive reasoning paths that mimic human thinking. Here’s how you can start:

1. Input Format

When you input a query, ensure it ends with ASSISTANT: to notify the model that it is ready to respond. Here’s an example:

query = USER: What should I do when I get cold? ASSISTANT:

2. Accessing the Model

You can access the Meerkat model using the apply_chat_template function. Here’s how:

from transformers import AutoModelForCausalLM, AutoTokenizer

device = 'cuda'  # Swap with 'cpu' if necessary
checkpoint = 'dmis-lab/meerkat-7b-v1.0'
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint, torch_dtype=torch.bfloat16)

# Engage in a multi-turn dialogue
messages = [
    {"role": "system", "content": "You are a helpful doctor..."},
    {"role": "user", "content": "Hello, doctor..."},
]
encodeds = tokenizer.apply_chat_template(messages, return_tensors='pt')
model_inputs = encodeds.to(device)
model.to(device)

generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True, pad_token_id=tokenizer.eos_token_id)
decoded = tokenizer.batch_decode(generated_ids)

print(decoded[0])

Understanding The Code with an Analogy

Imagine your communication with the Meerkat-7B model as setting up a scripted conversation, similar to preparing for a play. Here’s how it works:

• Characters and Roles: In our play, we have different roles: the ‘system’ sets the stage by describing the kind of conversation, while the ‘user’ is the patient with medical concerns. The ‘assistant’ is the doctor (our model) responding to queries based on the script.”
• Script Preparation: Just like actors need their lines, we prepare messages that guide the narrative of the dialogue. We provide context on what kind of assistance the doctor should deliver to the patient.
• Executing the Performance: When we ‘run’ the model, it’s like cueing the actors to start performing the play based on the prepared script. Each line of response is generated, simulating a human conversation.

Troubleshooting Tips

If you experience difficulties while using Meerkat-7B, here are some common issues and solutions:

• Model Not Responding: Ensure that the input ends with ASSISTANT:. This helps the model understand when to generate output.
• Memory Issues: If you encounter insufficient GPU memory errors, consider changing torch_dtype to torch.float32 or running the model on a CPU.
• Connection Errors: Ensure your internet connection is stable, especially if using remote resources.
