How to Use It
Once you have Langflow set up, you can begin creating workflows. Here’s a simple example to illustrate how to build a basic AI agent:
# Import necessary modules
from langflow import Langflow
# Create a new workflow
workflow = Langflow.create_workflow(name="MyFirstWorkflow")
# Add an agent to the workflow
agent = workflow.add_agent(name="ChatAgent", model="gpt-3.5-turbo")
# Define a simple flow
workflow.add_step(agent, "Hello, how can I assist you today?")
# Run the workflow
workflow.run()
This code snippet creates a workflow called "MyFirstWorkflow" with a ChatGPT agent that responds to user queries. You can expand this easily by adding more agents or steps as needed.
