And yet they have only improved marginally in my use cases since around Opus 4.5.

The harnesses have improved somewhat, but the code produced on large or legacy code bases is still very average and I still see similar mistakes made that I saw back a year ago (although less now that harnesses have become better at steering).

For my use cases, we are definitely on the flatter part of the curve at the moment.

This is wild to me, but to each their own. Mythos-class stuff is insanely better at nearly everything than Opus 4.5 was in my experience.
