I"d agree there is a fairly strong chance of parties whose IP may be being infringed looking to sue. This raises interesting questions about who they would sue though; likely not the developers, and the AI itself doesn't yet have legal personality so can't be sued. I reckon they would file suit against the company that owns and controls the AI (assuming it's a company; I don't know enough about the corporate structure above Chat GPT to opine just yet).

It's an analogous problem to 'whom do I sue if I get hit by a self driving car'

Wild times indeed
