Baseten's asynchronous inference allows for smooth processing of long-running requests, spikes in traffic, and request prioritization, reducing timeouts and improving GPU utilization. This method adds requests to a queue based on model capacity and priority, ensuring that tasks don't overwhelm the model and allowing for more efficient use of resources. It provides visibility and control over requests, enabling developers to track status, cancel requests as needed, and access results through webhooks or cloud storage, making it a robust solution for handling long-running jobs and spikes in traffic.
