# 利用規約

System One provides structured model evaluations. These notes describe current service behavior and your responsibilities.

Use only accounts and credentials you are authorized to use. Keep credentials private. You are responsible for actions your application takes using model outputs.

Model outputs can be incorrect. Verify performance for your use case and define appropriate human review. This website makes no latency, uptime, or individual prediction guarantee.

Usage is charged in credits under the displayed formula. Payment options depend on deployment configuration. Confirmed payment is required before purchased credits are available. Retain order and request identifiers for billing questions.

These pages describe this implementation. Additional commercial terms or retention periods must be supplied by the operator before they are represented as promises.
