  • Define Your Prompt

Create a prompt in a format that the model can understand.

TASK_PROMPT = "You are a helpful assistant."

  • Execute Function Calls

Use the model to generate function calls based on user queries.

3. Example Code Snippet

messages = [

    {"role": "system", "content": TASK_PROMPT},

    {"role": "user", "content": "What is the weather in Seattle?"}

]

inputs = tokenizer(messages, return_tensors="pt")

outputs = model.generate(inputs['input_ids'])

response = tokenizer.decode(outputs[0], skip_special_tokens=True)

print(response)

This code snippet demonstrates how to interact with the model, allowing it to process the user query and return the appropriate function call.
