Amazon Bedrock Knowledge Bases now supports cross-region inference

News



The article announces a new cross-region inference feature for Amazon Bedrock Knowledge Bases that enables developers to manage traffic bursts by utilizing compute across different AWS Regions.

Specifically, the article covers:

  • Cross-region inference allows higher throughput limits and enhanced resilience during peak demand periods
  • Developers no longer need to predict demand fluctuations, as traffic is dynamically routed across regions
  • To use cross-region inference, specify an inference profile as the "modelARN" in the RetrieveAndGenerate API request
  • No additional routing cost for using cross-region inference, charged based on the source region
  • Lists supported models and pre-defined regions, provides links to documentation and blog for getting started
