About Merlin

Merlin is an open-source platform for managing, deploying, and serving machine learning models in Kubernetes environments. It organizes work around Project, Model, Version, and Endpoint concepts to hide infrastructure complexity from users. It is built on Knative and KFServing to provide autoscaling serverless model serving.

You can install it for local development, follow documentation in the docs folder, and use the Python SDK or API to manage models. Client libraries for Golang and Python are generated with Swagger Codegen, and API docs can be run locally. It suits teams and developers already running Kubernetes who need self-serve model deployment.

The repository includes examples, database migrations, and contribution guidelines, and notes the project is still under active development. It is listed under machine-learning and mlops topics and uses an Apache-2.0 license.
