> My team of 6 people has been building a software to compete with an already established piece of software written by a major software corporation.

How long until that the devs at that major corporation start using an LLM? You think your smaller team can still compare to their huge team?

If the goal is to simply undercut the incumbent with roughly the same product than it doesn't really matter if the incumbent starts using LLMs too as their cost structure, margin expectations, etc. are already relatively set.
