Added mid-execution at Thom's request. Two consequences worth recording: it is a dropdown validated on the server rather than a free-text box, because a mistyped model name fails on every submission and surfaces only as drafts quietly not appearing; and the model list lives in one catalogue shared with the cost table, so the settings dropdown and the per-token rates cannot drift apart.
Rates confirmed against the pricing page rather than recalled. Worth having checked: an increase to $3/$15 had been scheduled for tomorrow and was cancelled, with $2/$10 made permanent.
