 Outlines provides a shortcut to do multi-label classification, using the `outlines.generate.choice` function to initialize a generator. Outlines uses multinomial sampling by default, here we will use the greedy sampler to get the label with the highest probability:

 generator = outlines.generate.choice(model, ["URGENT", "STANDARD"], sampler=greedy)
