With Langfuse, your team can collaboratively debug, analyze, and iterate on their LLM applications built with Novita AI. Its fully integrated features streamline the development workflow, enhancing efficiency and accelerating progress. This guide shows you how to integrate Novita AI with Langfuse. Novita AI’s API endpoints for chat, language and code are fully compatible with OpenAI’s API. This allows us to use the Langfuse OpenAI drop-in replacement to trace all parts of your application.

​
Prerequisites

Before you begin, make sure you have the following:
  • Novita AI LLM API Key:
    • Visit Novita AI’s website to create an account.
    • Log in and go to the Key Management page to generate your API Key, which is essential for integrating Novita AI’s models with Langfuse.
  • Langfuse Account:
    • Sign up for a Langfuse account on the official Langfusewebsite to start building powerful AI applications.

​
Integration Steps

​
Step 1: Install Dependencies

Ensure you have installed all the required Python packages: 
pip install openai langfuse

​
Step 2: Set Up Environment Variables

import os

# Get keys for your project from the project settings page
# https://cloud.langfuse.com

os.environ["LANGFUSE_PUBLIC_KEY"] = "pk-..." # DOCS EXAMPLE KEYS
os.environ["LANGFUSE_SECRET_KEY"] = "sk-..." # DOCS EXAMPLE KEYS
os.environ["LANGFUSE_HOST"] = "https://cloud.langfuse.com" # 🇪🇺 EU region
# os.environ["LANGFUSE_HOST"] = "https://us.cloud.langfuse.com" # 🇺🇸 US region


# Get your Novita AI API key from the project settings page
os.environ["NOVITA_API_KEY"] = "..."

​
Step 3: Langfuse OpenAI drop-in Replacement

In this step we use the native OpenAI drop-in replacement by importing from langfuse.openai import openai. To start using Novita AI with OpenAI’s client libraries, pass in your Novita AI API key to the api_key option, and change the base_url to https://api.novita.ai/v3/openai: 
# instead of import openai:
from langfuse.openai import openai

client = openai.OpenAI(
  api_key=os.environ.get("NOVITA_API_KEY"),
  base_url="https://api.novita.ai/v3/openai",
)
Note: The OpenAI drop-in replacement is fully compatible with the Low-Level Langfuse Python SDKs and @observe() decorator to trace all parts of your application.

​
Step 4: Run An Example

The following code cell shows how to use the traced OpenAI client to call Novita AI’s chat model. All API calls will be seamlessly traced by Langfuse. 
client = openai.OpenAI(
  api_key=os.environ.get("NOVITA_API_KEY"),
  base_url="https://api.novita.ai/v3/openai",
)

response = client.chat.completions.create(
  model="meta-llama/llama-3.1-70b-instruct",
  messages=[
    {"role": "system", "content": "Act like you are a helpful assistant."},
    {"role": "user", "content": "What are the famous attractions in San Francisco?"},
  ]
)

print(response.choices[0].message.content)

San Francisco, one of the most iconic cities in the world, is home to a plethora of famous attractions that cater to all interests and ages. Here are some of the most popular attractions in San Francisco:

Step 5: See Traces in Langfuse

After running the example model call, you can view the traces in Langfuse. These traces provide detailed information about your Novita AI API calls, including:
  • Request parameters (model, messages, temperature, etc.)
  • Response content
  • Token usage statistics
  • Latency metrics
