A generative AI model (such as Stable Diffusion) that does not store or reproduce, even transiently, the copyright works on which it was trained is not itself an 'infringing copy', so dealing in or providing hosted access to such a model in the UK does not amount to secondary copyright infringement; trade mark infringement can, however, arise where the model's outputs reproduce a registered mark (e.g. a watermark).
