Research, methodology, verified model prices and the calculator are free to read and use. Pro is being designed 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.
Launch status
There is nothing to buy today.
Billing is not live. There is no active checkout, trial, subscription, upgrade or paid entitlement. The Build Composer is an open product preview, and its current access and safety limits do not establish the final Free or Pro tiers.
The proposed price and feature boundary may change after recurring-value evidence is reviewed.

No payment method. Public pages do not require an account.
Explore and price a build
Read public research, methodology and verified model data
Use the calculator and model comparisons
Mix models under any named or custom harness in Build Composer, within the 24-role safety cap
Enter custom or contract rates, run sensitivity and break-even analysis, and download local JSON, CSV and PNG exports
When the Free-account Preview is enabled, it currently supports up to 20 plans, 100 immutable versions per plan and controlled unlisted links. It can save inactive alert settings, but it does not monitor prices or send email. These are preview safeguards, not promised final tier allowances.
Pro · planned, not for sale
$19/month or $190/year
Provisional USD price hypothesis. No plan can be purchased or reserved.
Keep the budget current
Higher finite plan and version allowances; the 24-role safety cap remains
Reusable cross-plan custom-rate and observed-usage profiles
Expanded architecture comparison and review workflows
Additional permissions and controls for unlisted review links
Active model-price and budget monitoring, only after delivery exists
The recurring hook is re-planning, review and monitoring—not access to public evidence.
Would that recurring workflow be worth $19/month?
Requires a free account so one person counts once. This is a research signal only—no plan is reserved and there is no upgrade, checkout, trial, subscription or charge.
Account-based research measurement is unavailable in this build. No interest can be submitted or charged.

“Planned” does not guarantee inclusion, timing or a final limit. Final entitlements will be enforced by the server before billing is enabled.
Before public checkout
Terms that still need a launch decision
These items will be decided and published before any public or live payment action is shown.
Trial
Decision pending. Before public or live checkout, Solvency must state whether there is no trial or publish its exact length and first billing date.
Cancellation
Decision pending. The cancellation method, effective date and remaining access must be published before a subscription can start.
Refunds
Decision pending. Eligibility, request window and contact process must be added to the Terms before checkout.
Tax
Decision pending. Checkout must say whether applicable tax is included or added and which currencies and regions are supported.
Required pre-checkout disclosure
A future purchase screen must show the final USD amount and billing cadence, automatic-renewal terms, trial treatment, cancellation timing, refund policy and tax treatment before payment is submitted. It must also link the then-current Terms and Privacy policy.
