Container Registry for AI: Managing 10TB+ Model Images and Dependencies

Updated December 8, 2025

December 2025 Update: LLM container sizes now routinely exceeding 100GB with 70B+ models. Harbor, GHCR, and ECR adding AI-specific features. GGUF and safetensors formats reducing redundant storage. OCI artifacts enabling non-container model distribution. Hugging Face Hub now hosting 1M+ models requiring new registry patterns. P2P distribution (Dragonfly, Kraken) essential for hyperscale deployments.

Hugging Face storing 5 million model artifacts totaling 300TB, NVIDIA's NGC catalog serving 10 billion container pulls monthly, and enterprises discovering their ML model images exceeding 50GB each demonstrate the unique challenges of containerized AI workloads.
