Speech technology company AssemblyAI operates speech-to-text inference workloads at scale on AWS. To execute these intensive workloads efficiently, the platform uses Amazon ECS combined with Amazon EC2 Spot GPU instances. This arrangement allows the company to target cost optimization while handling high-throughput speech recognition processing.

To support this setup, the operational pipeline integrates an Amazon SQS-based retry architecture. The combined infrastructure enables AssemblyAI to achieve 70% cost savings for its inference tasks. At the same time, the company continues maintaining SLA commitments across European Regions despite the use of spot compute capacity.

What this means for you

For engineering teams operating large-scale model inference, combining spot GPU instances with automated queue-based retries demonstrates a practical route to lowering cloud expenditures. The case highlights that maintaining strict service level commitments is possible even when relying on interruptible spot capacity. Companies operating across European regions can adopt similar architecture designs to control infrastructure overhead without sacrificing delivery reliability.
