AWS Bedrock + Auto/Premium — Which quota is actually being used?

Hi everyone,

I’m trying to better understand how Cursor behaves when integrating with AWS Bedrock, and I’m a bit confused about which quotas are actually being consumed.

Here’s my situation:

  • I configured AWS Bedrock as a provider in Cursor

  • When using Cursor, I selected both Auto and also tested Premium

  • However, I noticed that my “Auto” quota inside Cursor is still being consumed

This raised a couple of questions for me:

  1. When Bedrock is configured, does using Auto still rely on Cursor’s own models/providers, or should it route through my Bedrock account?

  2. If requests are actually going through Bedrock, is it expected that my Cursor Auto quota is still consumed?

  3. What is the exact difference in routing/consumption between Auto vs Premium vs explicitly using a Bedrock model?

My expectation was that once Bedrock is configured, the usage would primarily reflect on my AWS side (quota/billing), but the fact that Cursor’s internal quota is being consumed made me unsure about what’s actually happening under the hood.

If anyone has clarity on how this routing works or best practices to ensure Bedrock is actually being used, I’d really appreciate it.

Thanks!

Hey, good question. There’s an important detail here.

Auto and Premium are modes where Cursor picks the model for you and routes requests through Cursor servers. So it uses your Cursor quota (API pool), even if Bedrock is set up.

To send requests through your AWS Bedrock, you need to explicitly pick a specific Bedrock model in the model picker, not Auto or Premium. Only then will Cursor use your Bedrock credentials and the usage will be billed on the AWS side.

In short:

  • Auto / Premium: Cursor chooses the model, usage comes from Cursor quota
  • A Bedrock model selected explicitly: the request goes through your AWS account

So what you’re seeing is expected. If you want to use Bedrock, pick a specific model manually.

Let me know if you have any other questions.
