Today we are going to learn by developing a very simple application.
We are going to assemble a set of prompts into a working prototype service, utilizing orchestration tools
to link multiple calls to AI.
Python code below
import json
import requests
# Define the AI endpoints
ai_endpoints = {
"text_generation": "https://api.openai.com/v1/engines/davinci/completions",
"image_generation": "https://api.openai.com/v1/images/generation"
}
# Define the orchestration tool
class Orchestrator:
def __init__(self):
self.ai_endpoints = ai_endpoints
def call_ai(self, endpoint, prompt):
headers = {
"Authorization": "Bearer YOUR_API_KEY"
}
data = json.dumps({"prompt": prompt})
response = requests.post(endpoint, headers=headers, data=data)
return response.json()
def assemble_service(self, prompts):
service = {}
for prompt, endpoint in prompts.items():
response = self.call_ai(endpoint, prompt)
service[prompt] = response["result"]
return service
# Create an orchestrator object
orchestrator = Orchestrator()
# Define the prompts
prompts = {
"text_generation": "Write a poem about a cat",
"image_generation": "Generate an image of a cat"
}
# Assemble the service
service = orchestrator.assemble_service(prompts)
# Print the service output
print(service)
This code will call the OpenAI Text Completion and Image Generation endpoints to generate a poem and an image of a cat. The results of the AI calls are then assembled into a single service output.
This is just a simple example, of course. More complex services can be assembled by linking multiple AI calls together in a sequence or pipeline. For example, you could use the text generation output to generate an image caption, or you could use the image generation output to train a new AI model.
Orchestration tools can be used to simplify the process of linking multiple AI calls together. These tools typically provide a graphical user interface for designing and deploying workflows. Some popular orchestration tools include:
Prefect
Airflow
Kubeflow Pipelines
These tools can help you to automate the execution of your workflows and manage the dependencies between different AI calls.
Now let's create one small implementation as well.
Python code below
import json
import requests
class DCChargeManagement:
def __init__(self, station_id):
self.station_id = station_id
# Define the AI endpoints
self.ai_endpoints = {
"predict_demand": "https://api.openai.com/v1/engines/davinci/completions",
"optimize_charging": "https://api.openai.com/v1/images/generation"
}
# Define the orchestration tool
self.orchestrator = Orchestrator()
def predict_demand(self):
prompt = f"Predict the demand for DC charging at station {self.station_id} in the next hour."
response = self.orchestrator.call_ai(self.ai_endpoints["predict_demand"], prompt)
return response["result"]
def optimize_charging(self, demand_prediction):
prompt = f"Optimize the charging schedule for station {self.station_id} based on the following demand prediction: {demand_prediction}"
response = self.orchestrator.call_ai(self.ai_endpoints["optimize_charging"], prompt)
return response["result"]
def manage_charging(self):
demand_prediction = self.predict_demand()
charging_schedule = self.optimize_charging(demand_prediction)
# Send the charging schedule to the charging station controller
# ...
To use this class, you would first create an instance of the class, passing in the station ID as an argument. You would then call the predict_demand() method to get a prediction of the demand for DC charging at the station in the next hour. Next, you would call the optimize_charging() method to get an optimized charging schedule for the station, based on the demand prediction. Finally, you would send the charging schedule to the charging station controller.
This is just a basic example, of course. You could extend the class to include additional functionality, such as:
Support for multiple AI endpoints
Support for different orchestration tools
Support for multiple charging stations
Integration with other systems, such as a billing system or a customer relationship management (CRM) system
You could also use the class to develop a more sophisticated application, such as a mobile app that allows users to manage their DC charging sessions.
