The caller’s Lab AI usage for the current allowance period (else the last 30 days): credits spent per UTC day (every day, 0 included), the period’s total, the 20 costliest chats (title, Deep mode or not, credits, model calls, last use; a deleted chat keeps its cost with a null title) and how long the caller’s backtests of the last 7 days waited in the queue.
