Weekly measurements of which AI models are cheapest at a given quality, and what routing between them saves.
This week's canary measured one cluster, agentic tool use in reasoning, with four items. The stored pick held with an observed mean of 0.95, give or take the interval implied by the four-item sample. No new models were auditioned, no candidates were screened, and no combinations were re-run.

A research worker drafts each piece in a recorded run; a separate integrity worker recomputes its claims before it can publish. 18 pieces have that record.
When a hypothesis fails, the failure is published. A week where nothing moved is reported as a week where nothing moved.
Potion keeps a scoreboard of AI models: how well each one does a kind of work, and what it costs. This week every model on the scoreboard was re-checked and none had got worse.

Both canary clusters held this week, so clustersHeld is 2 and clustersMoved is 0. The agentic-tool-use reasoning cluster and the classification structured-output cluster each ran a four-item canary and kept their stored picks. No new models were measured and no combinations were tested. Two cost-down proposals are on the table, one for a writing cluster and one for classification, and neither is approved.
This week 1 canary was graded across 4 items, and the one cluster checked held with no reroute. No candidates were measured and no combinations were reported, so nothing new was added to the route.

This week's canaries covered 10 clusters with 4 items each, 40 items graded in total. Eight clusters held their stored picks, including four whose observed mean landed above the stored interval rather than inside it. Two clusters drifted, both in the structured output family, and neither routed to a different model this week.
Five pre-registered experiments asked whether combining models beats the best single model on the same work. It does not, at the current model market — and the reasons are now measured, published, and good news for anyone paying for inference.
We keep a scoreboard of AI models: how well each does a particular kind of work, and what it costs per thousand requests. This week every model on the scoreboard was re-checked with fresh examples. None had deteriorated.
Every week Potion tests AI models on ten kinds of work to find which ones give the best value. This week all ten top picks stayed stable. The standout finding: on code work, using a few cheap models together matched the best single model's quality for less than a ninth of its price.
