MLOps vs Plain Machine Learning
How shipping a model differs from training one in a notebook.
MLOps vs Plain Machine Learning 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.
Two Different Jobs
Training a model and shipping one are two different jobs. One ends in a notebook chart; the other ends with real users hitting your model every second.
What Plain ML Is
Plain machine learning is the science: you clean data, fit a model, and check its accuracy. Brilliant work, but it lives entirely on your laptop.
What MLOps Adds
MLOps is everything needed to run that model in the real world reliably: deploy it, watch it, and update it without breaking anything. 🚀
The Notebook Trap
A model in a notebook runs once, for you, on clean data you picked. Production runs forever, for strangers, on messy data you never saw.
model.fit(X_train, y_train)
print(model.score(X_test, y_test))Code Is Only Part
In normal software the code is the product. In ML the data shapes behavior too, so you must version and track data, not just code.
Models Go Stale
Code does not rot, but models do. The world shifts, so a model that was great last month can quietly decay into wrong answers.
It Is a Loop
Plain ML feels like a finish line. MLOps is a loop: deploy, monitor, learn, retrain, and deploy again, over and over.
Reproducibility Matters
You must be able to rebuild the exact same model later. That means pinning data, code, and environment so a run is fully reproducible.
More Than Accuracy
Offline accuracy is just one number. Production also cares about latency, uptime, and cost, because slow or pricey predictions still fail users.
Borrowed from DevOps
MLOps borrows the discipline of DevOps, the practice of automating software delivery, and stretches it to cover data and models too.
A Team Sport
Plain ML can be a solo effort. Shipping models is a team sport across data, engineering, and ops, so shared tooling really matters.
Quick Check
Let us test the core difference between training and shipping a model.
Recap
Plain ML builds a model; MLOps keeps it alive in production through deploy, monitor, and retrain. You now know why shipping is the real challenge. ✅
