I have been a major LLM skeptic and "late adopter." I had never actually used LLMs for anything at all (either in work or personal life) until about two months ago, although I had followed their development with interest and skepticism.

A couple months ago, I started using Claude for some tasks related to processing really messy data. Our company was making a big push for its use, and a co-worker gave me a fairly impressive demo of what he was able to do with this data in an hour or two.

Our company's Claude subscription defaulted to Opus 4.7 and we were encouraged to use it as much as we could.

I don't think I ever did more than 10 or 15 prompts in a day; I tend to do very detailed prompts and then spend 10-30 minutes playing around with the results and resulting code.

Today we get this:

> TL; DR: We're nearly at NNN Claude users and growing fast. Three quick asks: (1) default to Sonnet for everyday work; we have launched XXXXXXX to help with clarity, …

> …

> As we scale, let's be smart about how we work. Claude offers several models, and for everyday work — … — Sonnet is your go-to.
