Cheapest Decision Models per 1,000 Decisions
Cost per 1,000 decisions is the hosted input price at 200 input tokens per decision, the size of a typical state plus questions. Models below the median Decision Index score are left out, so the list is the cheapest of the competent ones; hosted models the Index has not scored yet are kept.

Frequently asked questions
What is the cheapest decision model?
Hosted prices for decision models are being loaded; this ranking fills in once they are.
How is cost per 1,000 decisions calculated?
Input price per 1M tokens × 200 tokens × 1,000 decisions. Decision models return probabilities rather than text, so output tokens are negligible.
Is self-hosting an open decision model cheaper?
At high volume, usually: small open models run on a CPU, and the cost is the compute you already pay for. See the open-weights and CPU rankings.
