Almost all of the results will not consist of 'jazz' in any real sense, but instead a collection of uncanny melodies and chord progressions that wonder around going nowhere, traditionally accompanied by an obscenely eye-offending diffusion model-generated mishmash of seasonal tropes and incongruent interior design choices. Often, it's MIDI bossa nova presumably written by either a machine or someone who's only ever heard a few bars of music at a time and has no idea that 'feel' or 'soul' are a thing.
