+## Model input prototype

+Notice that our Python model has different inputs than our R model:
+
+## R
+
+```{r}
+glimpse(inspect_train)
+```
+
+## Python
+
+```{python}
+X_train
+```
+

+::: {.callout-note icon=false}
+
+## Activity
+
+Call the `prototype` endpoints for both the Python and R model.
+
+How do they compare?

+## Model input prototype
+
+- In Python, you supply the model's input prototype via `prototype_data`
+- In R, the model input prototype is found automatically in most cases, but you can override this default via `save_prototype`
+- In both cases, it is ultimately up to you to decide what your API's inputs should be!

+
+The vetiver framework has sensible defaults but is extensible for more complex use cases
+
+## Your turn 🏺 {transition="slide-in"}
+
+::: {.callout-note icon=false}
+
+## Activity
+
+Pretend you need to customize your model API's inputs for a more complex use case.
+
+Make a new vetiver model object and change the input data prototype.
+
+Run an API locally for your new vetiver model object and explore the visual documentation. ^[Note that making predictions will not work now, since we haven't updated the API behavior to match these inputs.]
+
+Discuss a possible situation you might use this with your neighbor.
