Open-source CLI/Built on ModelPack

BUILT ON COMMON GROUND

ModelPackModel Spec aligned OCI▰ Open Container InitiativeOCI-compatible artifacts Apache 2.0Open code. Open possibilities.

LESS FRICTION. MORE BUILDING.

Model delivery.
Without the detours.

Your models don't need a separate universe. Bring weights, configuration, and code together, then put your existing infrastructure to work.

Many files. One artifact.

Package weights, config, code, and docs into a standard OCI model artifact with a declarative Modelfile.

Meet the Modelfile

Your registry. Already ready.

Push models to OCI-compatible registries. Keep the tags, authentication, and distribution workflows you already know.

Explore distribution

Just what you need.

Fetch files by pattern or extract models straight from a remote registry, without keeping an extra local artifact copy.

Work a little lighter

FROM YOUR DIRECTORY TO YOUR REGISTRY

Same workflow.
New possibilities.

Three familiar commands. One open path from local development to wherever your models go next.

~/my-modelbash

# Turn a model directory into an OCI artifact

modctl modelfile generate .

modctl build \
    -t registry.com/models/llama3:v1.0.0 \
    -f Modelfile .

Weights, configuration, code & docs

Model Spec artifact layout

Ready for your OCI registry

WORKFLOW EXAMPLE
~/my-modelbash

# Authenticate, then publish your model

modctl login -u YOUR_USERNAME registry.com

modctl push \
    registry.com/models/llama3:v1.0.0

Use your existing registry credentials

Publish a versioned model artifact

Share a reference, not a folder of files

WORKFLOW EXAMPLE
~/my-modelbash

# Bring the model to your workspace

modctl pull \
    registry.com/models/llama3:v1.0.0

modctl extract \
    registry.com/models/llama3:v1.0.0 \
    --output ./my-model

Retrieve a model by its registry reference

Extract the model files to your directory

Continue with your own inference tooling

WORKFLOW EXAMPLE

Not another platform. Just a better way to ship.

PART OF YOUR STACK. NOT A NEW ONE.

Built to fit.
Not to lock you in.

Built on the ModelPack Model Spec, modctl packages models as OCI-compatible artifacts. Choose where your models live, without choosing a proprietary format.

OPEN SOURCE. SHARED FUTURE.

Your next model.
A better way to ship it.

Start with your first artifact. Or help shape what comes next.
