+## Advanced Features
+
+### Adaptive Thinking
+
+:::note
+When using `reasoning_effort` with Claude Opus 4.7, all values (`low`, `medium`, `high`, `xhigh`) are mapped to `thinking: {type: "adaptive"}`. To use explicit thinking budgets with `type: "enabled"`, pass the native `thinking` parameter directly.
+:::
+
+<Tabs>
+<TabItem value="completions" label="/chat/completions">
+
+LiteLLM supports adaptive thinking through the `reasoning_effort` parameter:
+
+```bash
+curl --location 'http://0.0.0.0:4000/chat/completions' \
+--header 'Content-Type: application/json' \
+--header 'Authorization: Bearer $LITELLM_KEY' \
+--data '{
+  "model": "claude-opus-4-7",
+  "messages": [
+    {
+      "role": "user",
+      "content": "Solve this complex problem: What is the optimal strategy for..."
+    }
+  ],
+  "reasoning_effort": "high"
+}'
+```
+
+</TabItem>
+<TabItem value="messages" label="/v1/messages">
+
+Use the `thinking` parameter with `type: "adaptive"` to enable adaptive thinking mode:
+
+```bash
+curl --location 'http://0.0.0.0:4000/v1/messages' \
+--header 'x-api-key: sk-12345' \
+--header 'content-type: application/json' \
+--data '{
+    "model": "claude-opus-4-7",
+    "max_tokens": 16000,
+    "thinking": {
+        "type": "adaptive"
+    },
+    "messages": [
+        {
+            "role": "user",
+            "content": "Explain why the sum of two even numbers is always even."
+        }
+    ]
+}'
+```
+
+</TabItem>
+</Tabs>
+
+### Effort Levels
+
+Claude Opus 4.7 supports four effort levels: `low`, `medium`, `high` (default), and `xhigh`. These give you finer-grained control over how much reasoning the model applies to a task. Pass the effort level via the `output_config` parameter.
+
+`xhigh` is a new effort level introduced with Opus 4.7 that sits above `high`. The `max` effort level is Claude Opus 4.6 only and is not available on 4.7.
+
+<Tabs>
+<TabItem value="completions" label="/chat/completions">
+
+```bash
+curl --location 'http://0.0.0.0:4000/chat/completions' \
+--header 'Content-Type: application/json' \
+--header 'Authorization: Bearer $LITELLM_KEY' \
+--data '{
+  "model": "claude-opus-4-7",
+  "messages": [
+    {
+      "role": "user",
+      "content": "Explain quantum computing"
+    }
+  ],
+  "output_config": {
+    "effort": "xhigh"
+  }
+}'
+```
+
+**Using OpenAI SDK:**
+
+```python
+import openai
+
+client = openai.OpenAI(
+    api_key="your-litellm-key",
+    base_url="http://0.0.0.0:4000"
+)
+
+response = client.chat.completions.create(
+    model="claude-opus-4-7",
+    messages=[{"role": "user", "content": "Explain quantum computing"}],
+    extra_body={"output_config": {"effort": "xhigh"}}
+)
+```
+
+**Using LiteLLM SDK:**
+
+```python
+from litellm import completion
+
+response = completion(
+    model="anthropic/claude-opus-4-7",
+    messages=[{"role": "user", "content": "Explain quantum computing"}],
+    output_config={"effort": "xhigh"},
+)
+```
+
+You can combine `reasoning_effort` with `output_config` for even more fine-grained control over the model's behavior.

+
+**Effort level guide:**
+
+| Effort | When to use |
+|--------|-------------|
+| `low` | Short, fast responses — simple lookups, formatting, classification |
+| `medium` | Balanced tradeoff for everyday Q&A and light reasoning |
+| `high` (default) | Complex reasoning, code generation, analysis |
+| `xhigh` | Hardest problems — multi-step math, deep research, agentic planning |
