+# Helicone Tutorial 
+Helicone is an open source observability platform that proxies your OpenAI traffic and provides you key insights into your spend, latency and usage.
+
+## Use Helicone to log requests across all LLM Providers (OpenAI, Azure, Anthropic, Cohere, Replicate, PaLM)
+liteLLM provides `success_callbacks` and `failure_callbacks`, making it easy for you to send data to a particular provider depending on the status of your responses. 
+
+In this case, we want to log requests to Helicone when a request succeeds. 
+
+### Approach 1: Use Callbacks 
+Use just 1 line of code, to instantly log your responses **across all providers** with helicone: 
+```
+litellm.success_callback=["helicone"]
+```
+
+Complete code
+```python
+from litellm import completion
+
+## set env variables
+os.environ["HELICONE_API_KEY"] = "your-helicone-key" 
+
+# set callbacks
+litellm.success_callback=["helicone"]
+
+response = completion(model="gpt-3.5-turbo", messages=messages) 
+```
+
+### Approach 2: [OpenAI + Azure only] Use Helicone as a proxy
+Helicone provides advanced functionality like caching, etc. Helicone currently supports this for Azure and OpenAI.
+
+If you want to use Helicone to proxy your OpenAI/Azure requests, then you can - 
+
+- Set helicone as your base url via: `litellm.api_url` 
+- Pass in helicone request headers via: `litellm.headers` 
+
+Complete Code
+```
+import litellm
+from litellm import completion
+
+litellm.api_base = "https://oai.hconeai.com/v1"
+litellm.headers = {"Helicone-Auth": f"Bearer {os.getenv('HELICONE_API_KEY')}"}
+
+response = litellm.completion(
+    model="gpt-3.5-turbo",
+    messages=[{"role": "user", "content": "how does a court case get to the Supreme Court?"}]
+)
+
+print(response)
+```
