The terms for using Varsten

Varsten provides AI spend monitoring, proxy routing, response reuse, evals, guardrails, and savings proof tools.

You are responsible for protecting credentials, limiting access, and reporting lost or stolen keys promptly.

Optimize plans may charge a percentage of verified savings. Estimates and recommendations are not invoices by themselves.

You keep rights to prompts, responses, configurations, and application data, and allow Varsten to process data as needed to run the service.
