+Converting a model to ONNX format depends on the library that you use to create the model.
+In this case, the model is created with Scikit-Learn, so you must use the https://onnx.ai/sklearn-onnx/[sklearn-onnx] library to perform the conversion.
+
+To convert from PyTorch, see https://pytorch.org/tutorials/beginner/onnx/intro_onnx.html[Introduction to ONNX in the PyTorch docs].

+== Using `boto3`
+
+Although the previous section indicates that you should manually download the `rf_iris.onnx` file to your computer and upload it to S3, you can also upload your model directly from your notebook or Python file, by using the `boto3` library.
+To use this approach, you must:
+
+* Have the `boto3` library installed in your workbench (most of the RHOAI notebook images include this library).
+* Attach your data connection to the workbench.
+
+After training the model, you can upload the file as the following example demostrates:
+
+[source,python]
+----
+import os
+import boto3
+
+source_path = "model.onnx"
+s3_destination_path = "models/model.onnx"
+
+key_id = os.getenv("AWS_ACCESS_KEY_ID")
+secret_key = os.getenv("AWS_SECRET_ACCESS_KEY")

+[NOTE]
+====
+You can also use the `boto3` library to download data.
+This can be helpful in the data collection stage, for example for gathering data files from S3.

+=== Model Serving Request Body
+
+As you tested with the preceding `curl` command, to make HTTP requests to a deployed model you must use a specific request body format.
+The basic format of the input data is as follows:
+
+[subs=+quotes]
+----
+{
+  "inputs": [{
+    "name" : "input", <1>
+    "shape" : [2,3], <2>
+    "datatype"  : "INT64", <3>
+    "data" : [[34, 54, 65], [4, 12, 21]] <4>
+  }]
+}
+----
+<1> The name of the input tensor.
+The data scientist that creates the model must provide you with this value.
+<2> The shape of the input tensor.
+<3> The https://github.com/kserve/kserve/blob/master/docs/predict-api/v2/required_api.md#tensor-data-types[data type] of the input tensor.
+<4> The tensor contents provided as a JSON array.
+
+The API supports additional parameters.
+For a complete list, refer to the https://github.com/kserve/kserve/blob/master/docs/predict-api/v2/required_api.md#inference-request-json-object[Kserve Predict Protocol docs].
+
+To make a request in Python, you can use the `requests` library, as the following example shows:
+
+[source,python]
+----
+import requests
+
+input_data = [-0.15384616, -0.9909186]
+
+# You must adjust this path or read it from an environment variable
+INFERENCE_ENDPOINT = "https://my-model.apps.my-cluster.example.com/v2/models/my-model/infer"
+
+# Build the request body
+payload = {
+    "inputs": [
+        {
+            "name": "dense_input",
+            "shape": [1, 2],
+            "datatype": "FP32",
+            "data": input_data
+        }
+    ]
+}
+
+# Send the POST request
+response = requests.post(INFERENCE_ENDPOINT, json=payload)
+
+# Parse the JSON response
+result = response.json()
+
+# Print predicted values
+print(result['outputs'][0]['data'])
