What is Model Artifact Storage?
Model Artifact Storage is the repository for trained model files, weights, configurations, and associated metadata. It provides versioning, access control, retention policies, and efficient retrieval for deployment, enabling teams to manage model lifecycle and ensure artifact availability.
This glossary term is currently being developed. Detailed content covering implementation strategies, best practices, and operational considerations will be added soon. For immediate assistance with AI implementation and operations, please contact Pertama Partners for advisory services.
Model artifact storage is the foundation of ML model management. Without it, models live on individual laptops and shared drives, creating reproducibility failures, accidental overwrites, and compliance gaps. Proper artifact storage enables reliable rollbacks, audit trails, and team collaboration. Companies that implement structured artifact storage reduce model deployment failures by 50% and enable instant rollback capability that limits incident impact.

Success metrics include system uptime, model performance stability, deployment velocity, and operational cost efficiency.
Use a dedicated model registry like MLflow Model Registry, AWS SageMaker Model Registry, or Weights & Biases for model versioning and metadata. Store large binary artifacts in object storage like S3, GCS, or Azure Blob Storage. Use container registries for deployment-ready model images. Separate model weights from deployment configuration to enable independent updates. Choose storage with immutable versioning to prevent accidental overwrites. Budget $50-500/month depending on model count and size.
Implement lifecycle policies that transition old versions to cold storage like S3 Glacier after 90 days. Delete model versions that were never deployed to production after 30 days. Keep only the last 5-10 versions of each model in hot storage. Archive but never delete versions that were deployed to production for audit trail purposes. Monitor storage usage per model and alert when individual models exceed cost thresholds. Most teams find that 80% of storage is consumed by 20% of their models.
Store training data version, hyperparameters, evaluation metrics, Git commit hash, training duration, compute cost, creator identity, and intended deployment environment alongside every artifact. Include model cards with capability descriptions and known limitations. Add dependency manifests listing exact library versions. This metadata enables reproducing the model, understanding its provenance, and making informed deployment decisions. Without metadata, model artifacts are opaque files that require the original author to interpret.

A TPU, or Tensor Processing Unit, is a custom-designed chip built by Google specifically to accelerate machine learning and AI workloads, offering high performance and cost efficiency for training and running large-scale AI models, particularly within the Google Cloud ecosystem.
A model registry is a centralised repository for storing, versioning, and managing machine learning models throughout their lifecycle, providing a single source of truth that tracks which models are in development, testing, and production across an organisation.
A feature pipeline is an automated system that transforms raw data from various sources into clean, structured features that machine learning models can use for training and prediction, ensuring consistent and reliable data preparation across development and production environments.
An AI gateway is an infrastructure layer that sits between applications and AI models, managing routing, authentication, rate limiting, cost tracking, and failover to provide centralised control and visibility over all AI model interactions across an organisation.
Model versioning is the practice of systematically tracking and managing different iterations of AI models throughout their lifecycle, recording changes to training data, parameters, code, and performance metrics so teams can compare, reproduce, and roll back to any previous version.
