For work, Opus 4.8 because: - I'm on the base Claude Team plan, so no Fable access - Opus 5's outputs are wayyyy to verbose, to the point where I dread using it - Opus 4.8 is intelligent enough for my needs and doesn't make me dread reading

Outside of work, I'm using Codex's free tier with 5.6 Luna-High. My personal/volunteer projects are simple enough that I don't need much more.
