Managed Stack
The standing version of the audit: once a month we re-benchmark your actual model mix against current prices and send the switch list, plus an alert any week your number moves past your threshold.
Your model mix is priced against a market that changed under you 32 times last quarter — new prices, deprecations, terms shifts — and you usually find out when the invoice lands. A one-off optimization pass has a shelf life; the target keeps moving after you've stopped looking.
Monthly re-benchmark memo
Your stack recomputed against the latest prices: what moved, what to switch, the saving and the risk you dodged, the reasoning.
Threshold alerts
The same engine as Stack Watch, but on your actual model mix — any week the number moves past your threshold.

What a switch list looks like
Illustrative — real observed prices, not a client outcome
- Strong tier · Claude Sonnet 5 — $2.00 / $10.00 per Mtok. A step-up to $3.00 / $15.00 was scheduled for 1 Sep; Anthropic cancelled it on 10 Aug and made the lower rate permanent. We caught the schedule and then the cancellation — knowing a rise won't land is worth as much as knowing one will.
- Same capability bar, open weights — DeepSeek V4 Pro runs $0.66 / $1.98 per Mtok, up from $0.435 / $0.87 when its pricing rose and changed structure on 16 Aug. Whether your workload can tolerate that spread is the judgment call the memo makes for you.
- Workhorse tier — GPT-5.4-mini ($0.75 / $4.50) versus Gemini 3.1 Flash-Lite ($0.25 / $1.50): same tier, 3× apart on input.
