Apex Grid Shares Two-Stage GPU Preflight Check for Cron Agent Jobs

Apex Grid has described a two-stage preflight check it developed over several months to confirm GPU and serving-stack readiness before cron jobs run. The team argues that simply wrapping a job in a try/except block can hide failures caused by the GPU itself, such as another job monopolizing the card or an unresponsive kernel. The first stage queries a health endpoint, while the second runs a minimal inference request under a warmup timeout of roughly 3 to 10 seconds. The approach lets jobs be skipped cleanly when checks fail, which is useful when several cron jobs share a GPU pool, though it adds scheduling latency and requires specific endpoints. The company says it is exploring tuned lightweight warmup models and deeper Kubernetes integration.
