Ask HN: What makes startups with LLMs defensible in this market?

I'm currently talking to investors about my startup's seed round. A core part of our product is using LLMs to automate a common job.

Currently, our defensible narrative is that LLMs are just one part of our product and our complete solution is what presents a large opportunity.

I'm curious - especially to those who invest or raised recently in this space - what are key characteristics of defensible startups using LLMs.
