Free access renews at 00:00 UTC each day. Failed calls and calls without reported usage may still count against free access. Up to 10,000 evaluations and 1 GiB of input per account per UTC day; request size and rate limits also apply. Daily capacity may be limited.

What would a paid plan add?

We are exploring larger allowances, saved personal policies and longer history for people who use several agents. A paid plan would buy more capacity and better tools for comparing workflows. Pricing is not finalized, and there is no checkout yet.

What does "cheaper" mean for you?

A smaller decision call can reduce API work if it replaces enough expensive reasoning or filters context without damaging the answer. It can also add overhead. For a fixed-price chat subscription, fewer API-equivalent tokens do not automatically reduce your bill.

Compare complete tasks, including host tool calls, review and escalations. Studio records model attempts and reported tokens; provider invoices remain the authority for charges. Read the evidence before choosing a pattern.
