Pricing
Research, methodology, verified model prices and the calculator are free to read and use. Pro is for teams that repeatedly re-plan, review and monitor a multi-model build budget.
Solvency prices everything, the calculator, the frontier chart and Build Composer, the same way: cost per completed task, verified against a source. Pro is that same math applied to the plans you save.
Solvency takes no money from model vendors; the paid tier is what funds its independent benchmark runs.
Packaging
Public evidence stays free. Pro unlocks the full Build Composer and funds independent benchmark runs.

Pro funds the measurements. Solvency's benchmark runs, the measured cost-per-solved-task data this site exists to publish, are paid for by subscriptions, not by model vendors. One full run of a 90-task-per-model batch costs about $2,700: roughly 142 subscriber-months. You are not just buying software; you are funding independent measurement.
Roadmap, not sold as active features: a re-priced digest email, reusable rate profiles, usage import and an API. Model-price and budget monitoring (alerts) is not sold until it exists. Newly planned (2026-08-27), same rule: the AI spend audit, saved-stack re-pricing alerts, the data API, custom benchmark runs and verified harness-arena badges.
