Methodology

Open formula. Browser-based calculations. Source-dated rates. No API keys. No provider login. No tracing SDK. No account required. Input payloads are not stored.
Method scope: This calculator is driven by tool-specific method assumptions rather than the provider pricing register.

Model Ruler estimates AI architecture cost from user-provided assumptions: token volume, calls, context growth, cache behavior, retries, tool calls, automation-platform units, eval runs, observability volume, and self-host utilization.

Use these estimates for planning. Verify current provider rates and infrastructure terms before contracts or production commitments.
