Model autoscaling features on Baseten

The Baseten model autoscaling features are designed to automatically adjust the number of replicas in response to incoming traffic, ensuring that only paid-for computing resources are used. This is achieved through setting a minimum and maximum number of replicas, with scale-to-zero functionality allowing models to be put to sleep after a period of inactivity. The autoscaling window, scale down delay, and concurrency target controls further fine-tune the scaling behavior, while cold starts enable rapid response to new traffic with minimal delays. These features are designed to work together to ensure efficient use of computing resources, allowing developers to focus on building their models without worrying about the underlying infrastructure.
