Do Vercel Serverless Functions increase bandwidth usage?

On the Vercel platform, Serverless Function execution (GB-Hrs) will increase Bandwidth (GB) usage as well. Caching your Serverless Function(s) does not reduce the Bandwidth usage that comes with executing your Serverless Function(s). Check out the Usage tab in the Vercel Dashboard to see your Bandwidth usage for the past 30 days.

Note:

For usage guidelines, please check out our Typical Monthly Usage Guidelines documentation.
