+LiteLLM now supports GPT-5.4-mini and GPT-5.4-nano — cost-effective models for simple completions and high-throughput workloads.
+
+:::note
+If you're on **v1.82.3-stable** or above, you don't need any update to use these models.
+:::
+
+## Usage
+
+<Tabs>
+<TabItem value="proxy" label="LiteLLM Proxy">
+
+**1. Setup config.yaml**
+
+```yaml
+model_list:
+  - model_name: gpt-5.4-mini
+    litellm_params:
+      model: openai/gpt-5.4-mini
+      api_key: os.environ/OPENAI_API_KEY
+  - model_name: gpt-5.4-nano
+    litellm_params:
+      model: openai/gpt-5.4-nano
+      api_key: os.environ/OPENAI_API_KEY
+```
+
+**2. Start the proxy**
+
+```bash
+litellm --config /path/to/config.yaml
+```
+
+**3. Test it**
+
+```bash
+# GPT-5.4-mini
+curl -X POST "http://localhost:4000/v1/chat/completions" \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $LITELLM_KEY" \
+  -d '{
+    "model": "gpt-5.4-mini",
+    "messages": [{"role": "user", "content": "What is the capital of France?"}]
+  }'
+
+# GPT-5.4-nano
+curl -X POST "http://localhost:4000/v1/chat/completions" \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $LITELLM_KEY" \
+  -d '{
+    "model": "gpt-5.4-nano",
+    "messages": [{"role": "user", "content": "What is 2 + 2?"}]
+  }'
+```
+
+</TabItem>
+<TabItem value="sdk" label="LiteLLM SDK">
+
+```python
+from litellm import completion
+
+# GPT-5.4-mini
+response = completion(
+    model="openai/gpt-5.4-mini",
+    messages=[{"role": "user", "content": "What is the capital of France?"}],
+)
+print(response.choices[0].message.content)
+
+# GPT-5.4-nano
+response = completion(
+    model="openai/gpt-5.4-nano",
+    messages=[{"role": "user", "content": "What is 2 + 2?"}],
+)
+print(response.choices[0].message.content)
+```
+
+</TabItem>
+</Tabs>
+
+## Notes
+
+- Both models support function calling, vision, and tool-use — see the [OpenAI provider docs](../../docs/providers/openai) for advanced usage.
+- GPT-5.4-nano is the most cost-effective option for simple tasks; GPT-5.4-mini offers a balance of speed and capability.
