They claim the investment will be justified for a 1.5 year life span of the system. But LLMs are changing and improving at a much faster speed that 1.5 years feels like centuries!

I think modern LLMs are powerful enough now that they will still be useful in a couple years even if they aren't state-of-the-art. ChatGPT still lets you run their older model for cheaper than running GPT4, I could see a world where GPT4 is still available in 1.5 years even if there are better models out there.
