+### Example: 8192 Max Tokens
+
+The Anthropic beta `max-tokens-3-5-sonnet-2024-07-15` allows you to generate up to 8192 tokens.
+You can use it as follows:
+
+```ts highlight="6-8"
+import { anthropic } from '@ai-sdk/anthropic';
+import { streamText } from 'ai';
+
+const result = await generateText({
+  model: anthropic('claude-3-5-sonnet-20240620'),
+  // enable max tokens beta:
+  headers: { 'anthropic-beta': 'max-tokens-3-5-sonnet-2024-07-15' },
+  maxTokens: 8192, // important: specify max tokens
+  system:
+    "Don't shy away from generating long text. Follow the user's instructions'",
+  prompt:
+    'Invent a new holiday and describe its traditions. Write at least 20 pages.',
+});
+
+console.log(result.text);
+console.log('Token usage:', result.usage);
+```
+
