Ask HN: How do you create a moat if your product is based on a LLM API?

I have many ideas on how to use LLM to make something existing more efficient or to just create a new way of doing things.

All my ideas depend on using a foundational LLM such as GPT4 or Claude API which anyone has access to.

What are some ways to create moats for products that rely on foundational LLM APIs?
