Same for me, comfortable with a single Max sub, launching "claude --effort max" with Opus 4.8 (alas poor Fable, please come back!).

But try running Claude Opus at API prices through a 'clever' RAG based intermediate system 'managing' a 2024-era context size window completely unaligned with 2026 frontier model tool use expectations, that results in 100% cache miss and content coherency destruction on every single interaction. There's your typical 'Enterprise Agreement' GenAI setup.

I only really discovered this when trying to find out how my Enterprise friends' AI experiences were so completely opposite from my own successes as I could not believe how poor their results were even though on the surface it looked like we were using the same model, and I know they aren't 'bad' software engineers and developers.
