Depends on whether the startup is building a feature or a product. A lot of AI startups that are building on top of OpenAI are effectively building a feature, a small very specific solution for a small use-case. Most of those are going to fail when OpenAI or some other entity with a product will add that feature to their product. But, if you solve a real large pain point that has value and use LLMs via OpenAI to add 1 or more features to your offering which allows it to solve that pain point more effectively and differentiate from competitors, then you have a moat.
