Model Repository

The core definition of the model repository feature is to provide a Git-based version-controlled storage system for machine learning models, enabling teams to manage model files, track versions, and collaborate across tenants. It leverages Git LFS for large file storage and integrates with MLOps workflows to bridge model development and deployment.

Advantages

Git-native Version Control

  • Track model changes via commits/branches/tags, ensuring reproducibility.

High-Speed Transfers

  • CLI/Notebook uploads leverage internal network bandwidth.

Cross-Tenant Sharing

  • Shared models can be accessed across namespaces (e.g., public as a model marketplace).

Seamless Integration

  • Directly deploy models from the repository to inference services.

Core Features

Model Repository Creation & Deletion

  • Create an empty Git-backed repository with metadata (name/description/visibility).
  • Delete models after dependency checks (e.g., ensure no active inference services).

File Management

  1. CLI/Git LFS
    • Use git lfs track for large files (e.g., *.bin, *.h5).
    • Example: 
      git clone <model_repo_url>
git lfs install
cp ~/local_model/* . && git add . && git commit -m "v1.0" && git push

Version Control

  1. Branching
    • Maintain parallel versions (e.g., experimental vs main branches).
  2. Tagging
    • Mark releases via UI/CLI (e.g., git tag -a v2.0 -m "Stable release").
  3. Metadata Sync
    • Auto-read README.md from the default branch for model descriptions.

Cross-Tenant Sharing

  1. Shared Models
    • Set visibility to "Shared" during creation for inter-tenant access.
  2. Public Marketplace
    • Use public namespace to publish open-source models (e.g., HuggingFace conversions).

Integration with MLOps

  1. Deployment Ready
    • One-click inference service launch from tagged model versions.
  2. Notebook Integration
    • Pull models directly into AML Notebooks for testing: 
      !git clone https://aml-public/resnet50.git

Technical Notes

  1. Git LFS Requirement
    • Must include .gitattributes to specify LFS-tracked files (e.g., *.zip filter=lfs diff=lfs merge=lfs).
  2. Default Branch Rules
    • Misconfigured README.md metadata may block inference deployment.
