What CI/CD Means for Models
How ML pipelines differ from app CI/CD.
What CI/CD Means for Models is a free MLOps Academy lesson on CoddyKit — lesson 1 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the MLOps Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
CI/CD in One Breath
CI/CD means automating the steps between writing code and shipping it, so a machine checks and deploys your work instead of you doing it by hand. 🚀
CI: Continuous Integration
Continuous Integration runs your tests automatically every time you push code, catching breakage early instead of days later when it is painful to fix.
CD: Continuous Delivery
Continuous Delivery takes code that passed CI and automatically prepares or ships it to production, so releases stop being scary manual events.
ML Adds a Third Thing
Classic CI/CD ships code. ML pipelines also ship a trained model and the data it learned from, so you now have three moving parts to track, not one.
Tests That Check Behavior
App tests check logic. ML CI also checks model quality, asking did accuracy hold up, not just did the code run without crashing.
Builds Take Longer
A code build is seconds. Training a model can take minutes or hours, so ML pipelines often train on a small sample in CI and full data only on release.
Three Things to Reproduce
To rebuild any model exactly, you must pin its code, its data version, and its environment. CI/CD for ML makes pinning all three automatic.
The Artifact Is the Model
In app CI/CD the output is a binary. In ML the key artifact is the trained model file, which you version, store, and later deploy.
A Pipeline Has Stages
An ML pipeline chains clear stages: lint the code, run tests, train, evaluate, and only then build the deployable image.
stages = ["lint", "test", "train", "evaluate", "deploy"]Triggers Start the Pipeline
A trigger decides when a pipeline runs, like every push, every pull request, or a tagged release. You wire these rules once and never click again.
Why It Matters for ML
Without CI/CD, a model goes live only when someone remembers to run scripts. With it, every change is tested and shipped the same safe way each time.
Quick Check
What extra thing does ML CI/CD track that classic app CI/CD does not?
Recap
CI tests every change, CD ships it, and for ML you add the model and its data as tracked artifacts. Triggers and staged pipelines make releases safe and repeatable.
