The most recent model includes any enhancements to the previous GA and preview models. For example, to use the model version `2022-01-30-preview`, edit the `read` statement as shown:

See the [ComputerVisionClientOperationsMixin](/python/api/azure-cognitiveservices-vision-computervision/azure.cognitiveservices.vision.computervision.operations.computervisionclientoperationsmixin) methods, such as **read_in_stream**. Or, see the sample code on [GitHub](https://github.com/Azure-Samples/cognitive-services-quickstart-code/blob/master/python/ComputerVision/ComputerVisionQuickstart.py) for scenarios involving local images.
