response = model.generate_content(long_prompt_parts)
print(response.text)
    

Step 4: Implementing Function Calling (Tool Use)

Function calling allows your Gemini model to interact with external tools. You define the tools, and Gemini decides when and how to use them.

# Example of defining a tool and using it with Gemini
from vertexai.generative_models import GenerativeModel, Tool, FunctionDeclaration

# Define a function to get current stock price
get_stock_price_func = FunctionDeclaration(
    name="get_stock_price",
    description="Gets the current stock price for a given ticker symbol.",
    parameters={
        "type": "object",
        "properties": {
            "ticker": {"type": "string", "description": "The stock ticker symbol (e.g., GOOG)"}
        },
        "required": ["ticker"],
    },
)

# Create a tool with the function
stock_tool = Tool(function_declarations=[get_stock_price_func])

# Initialize the model with the tool
model_with_tool = GenerativeModel("gemini-1.5-pro-preview-0514", tools=[stock_tool])

# Example interaction
chat = model_with_tool.start_chat()
response = chat.send_message("What is the stock price of Google?")

# The model will call the tool. You'll need to implement the actual function execution.
# The response will contain a FunctionCall object.
# You then execute the function and send the result back to the model.
print(response.candidates[0].function_calls)
# Example of handling the function call (simplified)
# if response.candidates[0].function_calls:
#     for call in response.candidates[0].function_calls:
#         if call.name == "get_stock_price":
#             # In a real app, you'd call a real API here
#             fake_price = {"ticker": call.args["ticker"], "price": 175.50}
#             response_after_tool = chat.send_message(Part.from_function_response(name="get_stock_price", response=fake_price))
#             print(response_after_tool.text)
