To make this more confusing, there is a fast mode of Opus 4.6, which (as far as I understand it) is supposed to deliver the same results as the standard mode. It's much more expensive, but advertised as more interactive.
replyOpus is not cost effective.

replyCompared to what? I spent about $700 last month on Cursor, mostly on Opus 4.6. The time it saved me is at least 10-20x more valuable than that. I keep trying to use GPT-5.3 Codex, because it's like 40% cheaper, but then the quality doesn't always seem quite as good, and it's honestly not worth it to me to save a couple hundred bucks a month for something that's 10% worse. The multiplicative value of what I'm building means it's worth it to pay extra for the SOTA model in almost all cases.
