modelUnits
Number of model units to allocate. A model unit delivers a specific throughput level for the specified model. The throughput level of a model unit specifies the total number of input and output tokens that it can process and generate within a span of one minute. By default, your account has no model units for purchasing Provisioned Throughputs with commitment. You must first visit the Amazon Web Services support center to request MUs.
For model unit quotas, see Provisioned Throughput quotas in the Amazon Bedrock User Guide.
For more information about what an MU specifies, contact your Amazon Web Services account manager.
