Which serverless GPU platforms actually have fast cold starts for AI inference — p99, not p50

been testing this properly for a few months because i kept seeing wildly different claims and couldn’t find real data anywhere. specifically for inference workloads, 70B class models, and i care about p99 not p50 because p99 is what shows up in user complaints, not the median. the thing nobody explains clearly: cold start has two components. model loading time — which is roughly fixed based on model size and doesn’t vary much across platforms — and infrastructure queue time, which is where all t
