yep. I'm saying that the managed agent API described in the article is API only.

That's the thing. I did notice that, and switched back to my favorite (5.6 sol, medium). No difference.

Looks to me like they really took down the quotas, especially anything in codex. Either that or it's something else, perhaps in codex?

That sounds like large amounts of context (maybe from memory or history?) are chewing through your quota, context that hadn't yet had a chance to build up in your newer account. That's just a guess, I'm not an account holder there or anything so I can't try to re-create it on my end. You could try to erase history on your old account too, too see if it makes a difference. 'Course, then you'd lose all that history!

If true, that sounds like something that could actually be monitored by third parties, similar to the performance degradation trackers.
