Tell HN: Cursor Auto is no longer "Auto"! Let's welcome Auto Cost

Cursor's "Auto", to me, used to mean "cheap flat rate, don't worry which model ran". That assumption is now a financial mishap waiting to happen as of today: 2026-07-22.

Cursor just shipped "Cursor Router" [1].

Auto in the model picker is now three modes, no longer one:

- Intelligence - frontier quality

- Balance - "daily driver" frontier quality

- Cost - the previous Auto routing, with fixed per-token prices (per Colin on the forum [2])

Balance and Intelligence now bills at whatever model the router actually picks and *draws from your API usage tier*.

So if you're still on "Auto" and see "GPT-5.6 Sol (Auto Balanced)" billed to your account under On-Demand, that's now *expected*: while you didn't pick Sol manually, Cursor's "Auto Balance" (which I believe is the default?) did, at Sol's API rates and billed you for it.

It's possible I was the only person caught off-guard with this change - a banner/toast/popup would really have been nice but in case you're caught off-guard too, now you know.
