+# LiteLLM Proxy (LLM Gateway)
+
+
+**[LiteLLM Proxy](../simple_proxy) is OpenAI compatible**, you just need the `openai/` prefix before the model
+
+:::tip
+
+[LiteLLM Providers a **self hosted** proxy server (AI Gateway)](../simple_proxy) to call all the LLMs in the OpenAI format
+
+:::
+
+## Required Variables
+
+```python
+os.environ["OPENAI_API_KEY"] = "" # "sk-1234" your litellm proxy api key 
+os.environ["OPENAI_API_BASE"] = "" # "http://localhost:4000" your litellm proxy api base
+```
+
+
+## Usage (Non Streaming)
+```python
+import os 
+import litellm
+from litellm import completion
+
+os.environ["OPENAI_API_KEY"] = ""
+
+# set custom api base to your proxy
+# either set .env or litellm.api_base
+# os.environ["OPENAI_API_BASE"] = ""
+litellm.api_base = "your-openai-proxy-url"
+
+
+messages = [{ "content": "Hello, how are you?","role": "user"}]
+
+# openai call
+response = completion(model="openai/your-model-name", messages)
+```
+
+## Usage - passing `api_base`, `api_key` per request
+
+If you need to set api_base dynamically, just pass it in completions instead - completions(...,api_base="your-proxy-api-base")
+
+```python
+import os 
+import litellm
+from litellm import completion
+
+os.environ["OPENAI_API_KEY"] = ""
+
+messages = [{ "content": "Hello, how are you?","role": "user"}]
+
+# openai call
+response = completion(
+    model="openai/your-model-name", 
+    messages, 
+    api_base = "your-litellm-proxy-url",
+    api_key = "your-litellm-proxy-api-key"
+)
+```
+## Usage - Streaming
+
+```python
+import os 
+import litellm
+from litellm import completion
+
+os.environ["OPENAI_API_KEY"] = ""
+
+messages = [{ "content": "Hello, how are you?","role": "user"}]
+
+# openai call
+response = completion(
+    model="openai/your-model-name", 
+    messages, 
+    api_base = "your-litellm-proxy-url", 
+    stream=True
+)
+
+for chunk in response:
