## Pre-Requisites
Make an account on [Arize AI](https://app.arize.com/auth/login)

## Quick Start
Use just 2 lines of code, to instantly log your responses **across all providers** with arize


```python
litellm.callbacks = ["arize"]
```
```python
import litellm
import os

os.environ["ARIZE_SPACE_KEY"] = ""
os.environ["ARIZE_API_KEY"] = "" # defaults to litellm-completion

# LLM API Keys
os.environ['OPENAI_API_KEY']=""

# set arize as a callback, litellm will send the data to arize
litellm.callbacks = ["arize"]
 
# openai call
response = litellm.completion(
  model="gpt-3.5-turbo",
  messages=[
    {"role": "user", "content": "Hi 👋 - i'm openai"}
  ]
)
```

### Using with LiteLLM Proxy


```yaml
model_list:
  - model_name: gpt-4
    litellm_params:
      model: openai/fake
      api_key: fake-key
      api_base: https://exampleopenaiendpoint-production.up.railway.app/
