Core Components of Azure OpenAI Assistants
To effectively implement and utilize Azure OpenAI Assistants, it's crucial to understand its main components:
- Assistant: The AI agent configured with specific instructions, model parameters, and available tools.
- Thread: A conversation session between the Assistant and a user, storing Messages.
- Message: A unit of communication within a Thread, which can include text, images, and files.
- Run: The process of activating an Assistant to perform tasks based on the Thread content.
- Run Step: A detailed sequence of actions performed by the Assistant during a Run.
Implementing Azure OpenAI Assistants
Let's explore the practical aspects of implementing Azure OpenAI Assistants using Python. This section will cover environment setup, API integration, and essential coding practices for creating and managing AI assistants.
Setting Up the Environment
First, ensure you have the necessary credentials and environment variables set up:
import os
from openai import AzureOpenAI
client = AzureOpenAI(
api_key=os.getenv("AZURE_OPENAI_API_KEY"),
api_version=os.getenv("AZURE_OPENAI_VERSION"),
azure_endpoint=os.getenv("AZURE_OPENAI_ENDPOINT")
)
Creating Specialized Assistants
Here's an example of creating two specialized assistants for a healthcare scenario:
patient_assistant = client.beta.assistants.create(
name="Appointment Summary Assistant",
instructions=(
"You are an AI assistant designed to retrieve and summarize patient appointment details. "
"When asked to provide an appointment summary, follow these steps: "
"1. Access the patient's appointment data. "
"2. Extract relevant details such as appointment date, time, doctor, and purpose. "
"3. Summarize the information in a clear and concise format. "
"4. If the data retrieval is unsuccessful, notify the user and attempt to retrieve the information again."
),
tools=[{"type": "code_interpreter"}],
model=MODEL_NAME
)
doctor_assistant = client.beta.assistants.create(
name="Doctor Available Appointments Assistant",
instructions=(
"You are an AI assistant designed to help users find available appointments with doctors. "
"When asked to provide available appointment slots, follow these steps: "
"1. Access the doctor's schedule and check for open time slots. "
"2. Filter the results based on the user's preferences, such as date, time, and specific doctor. "
"3. Present the available appointments in a clear and organized manner. "
"4. If no appointments are available, suggest alternative dates or doctors. "
"5. If the data retrieval is unsuccessful, notify the user and attempt to retrieve the information again."
),
tools=[{"type": "code_interpreter"}],
model=MODEL_NAME
)
Managing Assistants
To retrieve and manage assistants:
def get_assistants_list(order: str = "asc", limit: int = 5) -> List:
assistants = assistant_client.beta.assistants.list(
order=order,
limit=limit,
)
return assistants.data
def get_assistant_by_name(assistant_client, assistant_name: str):
existing_assistants = get_assistants_list()
assistant_names = {assistant.name: assistant for assistant in existing_assistants}
if assistant_name in assistant_names:
return assistant_names[assistant_name]
raise AssistantNotFoundException(f"Assistant '{assistant_name}' not found.")
Creating and Managing Threads
Threads are essential for maintaining conversation context:
new_thread = assistant_client.beta.threads.create()
assistant_client.beta.threads.messages.create(
thread_id=new_thread.id,
role="user",
content=data
)
assistant_run = assistant_client.beta.threads.runs.create(
thread_id=new_thread.id,
assistant_id=appointment_assistant.id
)
Advanced Implementation: Multi-Agent System
To create a more sophisticated system, we can implement a planner assistant that orchestrates multiple specialized assistants:
planner_assistant_name = "appointment_assistants_planner"
agent_arr = ["patient_appointment_assistant", "doctor_appointment_assistant"]
instructions_pa = f"""
As a user proxy agent, your primary function is to streamline dialogue between the user and the specialized agents within this group chat.
You have access to the following agents to accomplish the task:
{'\n'.join(agent_arr)}
If the agents above are not enough or are out of scope to complete the task, then run send_message with the name of the agent.
When outputting the agent names, use them as the basis of the agent_name in the send message function, even if the agent doesn't exist yet.
Run the send_message function for each agent name generated.
Do not ask for follow-up questions, run the send_message function according to your initial input.
Plan:
1. patient_appointment_assistant extracts Patient appointment information
2. doctor_appointment_assistant analyzes doctor appointment info

Utilizing Azure OpenAI Assistants in Healthcare
Now that we've implemented our assistants, let's explore how to effectively utilize them in real-world healthcare scenarios.
Appointment Management System
In our healthcare example, we've created two specialized assistants:
- Patient Appointment Summary Assistant
- Doctor Available Appointments Assistant
These assistants can work in tandem to provide a comprehensive appointment management system. Here's how we can utilize them:
thread = assistant_client.beta.threads.create()
user_message = "Give me appointments of patient name XYZ"
message = query_with_message(user_message, assistants_planner, thread)
print(message)
This code snippet demonstrates how to initiate a conversation with the planner assistant, which will then coordinate with the specialized assistants to retrieve and present the requested information.
Enhancing Assistant Capabilities for Healthcare
To further enhance the capabilities of our assistants in a healthcare context, consider implementing the following:
-
Data Integration: Connect assistants to relevant Electronic Health Record (EHR) systems and healthcare databases to access real-time patient information and doctor schedules.
