While steady players have emerged in certain vertical domains—such as legal tech, medical coding, and enterprise-specific internal tools—none have yet reached true "super unicorn" status. Looking ahead, these vertical players will likely need to build their own Vertical Domain Models, fine-tuning or continuing pre-training on general-purpose LLM foundations and injecting massive volumes of proprietary domain data (patient records, statutes, case law, enterprise knowledge bases, internal documentation, and more). For Cursor to pull off another leapfrog moment and reclaim leadership in AI coding, it must develop its own LLM. Without one, it risks never again becoming the category leader in this space. In short, any solution that simply plugs into third-party LLM APIs will not evolve into an independent third-paradigm species. True third-paradigm players will not be built on direct API access to existing LLMs.
