See this as one of the major selling points.
…but I haven’t joined a new company since LLMs were a thing. How often is this use case necessary to justify $Ts in investment?
No ieda about that, those are amounts of money I can't even consider because I couldn't tell the different of T vs B or even a hundred millions (as someone who never had more than 100k).
It's something I would cosnider paying for the first months when joining a new company (specially with a good salary), but not more than that, to be honest.
Agree, specially useful when you join a new company and you have to navegate a large codebase (or bad-maintained codebase, which is even worse by several orders of magnitude). I had no luck asking LLM to fix this or that, but it did mostly OK when I asked how it works and what the code is trying to code (it includes mistakes but that's fine, I can see them, which is different if it was just code that I copy and paste).
