Introducing usage-based pricing for Amazon SageMaker AI bidirectional streaming

AWS announced usage-based metering for Amazon SageMaker AI bidirectional streaming inference, letting model providers report actual usage for AWS Marketplace software charges via a companion WebSocket metadata connection, while SageMaker AI endpoint infrastructure charges still apply. Deepgram is the launch partner, bringing usage-based Speech-to-Text and Text-to-Speech billing to AWS Marketplace. Model servers opt in with the X-Amzn-SageMaker-Metadata-Stream-Supported header and send JSON metering records with the inference.count dimension and ConsumedUnits.
