Amazon Braket Quotas
The following table lists the service quotas for Amazon Braket. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account.
Some quotas can be increased. For more information, see AWS service quotas.

Burst rate quotas cannot be increased.

The maximum rate increase for adjustable quotas (except burst rate, which cannot be adjusted) is 2X the specified default rate limit. For example, a default quota of 60 can be adjusted to a maximum of 120.

The adjustable quota for concurrent SV1 (DM1) tasks allows a maximum of 50 per AWS Region.
