PostgresML automatically deploys a model for online predictions after training, if the**key metric** isabetter than the currently deployed model. We'll train many models over time for this project, and you can read more about deployments later.

PostgresML automatically deploys a model for online predictions after training, if the**key metric** is better than the currently deployed model. We'll train many models over time for this project, and you can read more about deployments later.

Once a model is trained, you can use`pgml.predict` to use it on new inputs.`pgml.predict` is a function that takes our project name, along with an array of features to predict on. In this case, our features areth`title_rank` and`body_rank`. We can use the`pgml.predict` function to make predictions on the training data, but in a real application, we'd want to make predictions on new data that the model hasn't seen before. Let's do a quick sanity check, and see what the model predicts for all the values of our training data.
