AIProjectClient - Your Entry Point — The Foundry SDK

Connecting to Your Project

The AIProjectClient is the main class you instantiate to interact with your Foundry project.

Python Quick Start

from azure.ai.projects import AIProjectClient
from azure.identity import DefaultAzureCredential

project = AIProjectClient(
    endpoint="<your-project-endpoint>",
    credential=DefaultAzureCredential()
)

# Get an OpenAI-compatible client
openai_client = project.get_openai_client()
response = openai_client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello from Foundry!"}]
)
print(response.choices[0].message.content)

# Recommended in 2026: OpenAI Responses API (stateful multi-turn & tools)
resp = openai_client.responses.create(
    model="gpt-6.1-sol",
    input="Explain Foundry Agent Service in one concise paragraph."
)
print(resp.output_text)

using Azure.Identity;
