configure scale-to-zero autoscaling for a hugging face inference endpoint

Steps
Open the endpoint's Settings page and enable Automatic Scale-to-Zero
Set the minimum replica count to 0, which is required for the endpoint to actually scale down to zero replicas
Understand the default idle behavior: the endpoint scales to zero after a period of inactivity based on request patterns, not accelerator utilization
Optionally add the X-Scale-Up-Timeout header to client requests so the proxy holds the request until a replica is ready instead of immediately erroring
Test the cold-start path end-to-end and confirm client code tolerates a 502 Bad Gateway during the replica initialization window after scale-up
Known gotchas
Scale-to-zero is request-pattern-based, not GPU-utilization-based — behavior differs from accelerator-metric-based autoscalers
Without the X-Scale-Up-Timeout header, the first request after a cold endpoint wakes up can receive a 502 rather than waiting for the replica to become ready
Minimum replicas must be explicitly set to 0 — leaving it at a nonzero default silently disables scale-to-zero even if the feature toggle is on
