Azure API Load-Balancing​

Use this if you're trying to load-balance across multiple Azure/OpenAI deployments.

Router prevents failed requests, by picking the deployment which is below rate-limit and has the least amount of tokens used.

In production, Router connects to a Redis Cache to track usage across multiple deployments.

Quick Start​

pip install litellm
from litellm import Router

model_list = [{ # list of model deployments
"model_name": "gpt-3.5-turbo", # openai model name
"litellm_params": { # params for litellm completion/embedding call
"model": "azure/chatgpt-v-2",
"api_key": os.getenv("AZURE_API_KEY"),
"api_version": os.getenv("AZURE_API_VERSION"),
"api_base": os.getenv("AZURE_API_BASE")
},
"tpm": 240000,
"rpm": 1800
}, {
"model_name": "gpt-3.5-turbo", # openai model name
"litellm_params": { # params for litellm completion/embedding call
"model": "azure/chatgpt-functioncalling",
"api_key": os.getenv("AZURE_API_KEY"),
"api_version": os.getenv("AZURE_API_VERSION"),
"api_base": os.getenv("AZURE_API_BASE")
},
"tpm": 240000,
"rpm": 1800
}, {
"model_name": "gpt-3.5-turbo", # openai model name
"litellm_params": { # params for litellm completion/embedding call
"model": "gpt-3.5-turbo",
"api_key": os.getenv("OPENAI_API_KEY"),
},
"tpm": 1000000,
"rpm": 9000
}]

router = Router(model_list=model_list)

# openai.chat.completions.create replacement
response = router.completion(model="gpt-3.5-turbo",
messages=[{"role": "user", "content": "Hey, how's it going?"}]

print(response)

Redis Queue​

router = Router(model_list=model_list, 
redis_host=os.getenv("REDIS_HOST"),
redis_password=os.getenv("REDIS_PASSWORD"),
redis_port=os.getenv("REDIS_PORT"))

print(response)

Parallel Function calling​

See a detailed walthrough of parallel function calling with litellm here

# set Azure env variables
import os
os.environ['AZURE_API_KEY'] = "" # litellm reads AZURE_API_KEY from .env and sends the request
os.environ['AZURE_API_BASE'] = "https://openai-gpt-4-test-v-1.openai.azure.com/"
os.environ['AZURE_API_VERSION'] = "2023-07-01-preview"

import litellm
import json
# Example dummy function hard coded to return the same weather
# In production, this could be your backend API or an external API
def get_current_weather(location, unit="fahrenheit"):
"""Get the current weather in a given location"""
if "tokyo" in location.lower():
return json.dumps({"location": "Tokyo", "temperature": "10", "unit": "celsius"})
elif "san francisco" in location.lower():
return json.dumps({"location": "San Francisco", "temperature": "72", "unit": "fahrenheit"})
elif "paris" in location.lower():
return json.dumps({"location": "Paris", "temperature": "22", "unit": "celsius"})
else:
return json.dumps({"location": location, "temperature": "unknown"})

## Step 1: send the conversation and available functions to the model
messages = [{"role": "user", "content": "What's the weather like in San Francisco, Tokyo, and Paris?"}]
tools = [
{
"type": "function",
"function": {
"name": "get_current_weather",
"description": "Get the current weather in a given location",
"parameters": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "The city and state, e.g. San Francisco, CA",
},
"unit": {"type": "string", "enum": ["celsius", "fahrenheit"]},
},
"required": ["location"],
},
},
}
]

response = litellm.completion(
model="azure/chatgpt-functioncalling", # model = azure/<your-azure-deployment-name>
messages=messages,
tools=tools,
tool_choice="auto", # auto is default, but we'll be explicit
)
print("\nLLM Response1:\n", response)
response_message = response.choices[0].message
tool_calls = response.choices[0].message.tool_calls
print("\nTool Choice:\n", tool_calls)

Authentication with Azure Active Directory Tokens (Microsoft Entra ID)​

This is a walkthrough on how to use Azure Active Directory Tokens - Microsoft Entra ID to make litellm.completion() calls

Step 1 - Download Azure CLI Installation instructons: https://learn.microsoft.com/en-us/cli/azure/install-azure-cli

brew update && brew install azure-cli

Step 2 - Sign in using az

az login --output table

Step 3 - Generate azure ad token

az account get-access-token --resource https://cognitiveservices.azure.com

In this step you should see an accessToken generated

{
"accessToken": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6IjlHbW55RlBraGMzaE91UjIybXZTdmduTG83WSIsImtpZCI6IjlHbW55RlBraGMzaE91UjIybXZTdmduTG83WSJ9",
"expiresOn": "2023-11-14 15:50:46.000000",
"expires_on": 1700005846,
"subscription": "db38de1f-4bb3..",
"tenant": "bdfd79b3-8401-47..",
"tokenType": "Bearer"
}

Step 4 - Make litellm.completion call with Azure AD token

Set azure_ad_token = accessToken from step 3 or set os.environ['AZURE_AD_TOKEN']

response = litellm.completion(
model = "azure/<your deployment name>", # model = azure/<your deployment name>
api_base = "", # azure api base
api_version = "", # azure api version
azure_ad_token="", # your accessToken from step 3
messages = [{"role": "user", "content": "good morning"}],
)
