## Balance and estimates

The landing calculator uses USD-equivalent account credit; the console displays balance in CNY. A display currency is not a payment quote. Check the actual wallet and current model group rate; do not infer an exchange rate or promotional bonus.

## Current access

New registration and online top-ups are closed; no active credit bonus is included in estimates. Claude/GPT/Gemini remain unavailable placeholders. Model listings and group access do not promise a service-level guarantee or unlimited throughput.

## Reconcile usage

Keep model ID, group, time and request/task ID. Compare the response usage with the console records. Do not put secret keys into diagnostic logs.
