A Guide to AI Cold Starts on Cloud Run

A Guide to AI Cold Starts on Cloud Run

Short summary

Cloud Run AI inference experiences 20-second cold starts due to four startup phases: GPU allocation, image streaming, engine initialization, and model weight loading into VRAM. Optimize using 4-bit quantization, concurrent Cloud Storage downloads, Startup CPU Boost, and Direct VPC Egress with Private Google Access. Tuning concurrency alongside storage strategy enables production-grade AI inference at scale.

  • •Four-phase cold start breakdown: GPU allocation, image streaming, engine initialization, model weight loading
  • •4-bit quantization plus concurrent Cloud Storage downloads reduce startup time dramatically
  • •Infrastructure settings (CPU Boost, VPC Egress, Private Google Access) and concurrency tuning are critical for production
