 ### `maxDuration`
 
-Based on your deployment platform, you may be able to use a higher default execution time for your function.
-This setting allows you to opt into a higher execution time within your plans limit.
+By default, Next.js does not limit the execution of server-side logic (rendering a page or handling an API).
+Deployment platforms can use `maxDuration` from the Next.js build output to add specific execution limits.
+For example, on [Vercel](https://vercel.com/docs/functions/serverless-functions/runtimes#max-duration).

 **Note**: This settings requires Next.js `13.4.10` or higher.
