Credits work like tokens: every run costs shots × the machine's per-shot rate, debited from your balance. Every rate is on this page. Every new account starts with 100 free credits — no card required.

Before anything is charged, the platform prices the run — POST /runs/quote — from the live catalog and your organisation's rate. The console, the lab and the SDK all show that number, never a local guess.
On submit the cost is held against your balance. A simulator run settles in seconds; a real machine may sit in a queue for hours — the hold is what makes the queue honest.
When the run completes, the hold settles. Cancel a queued run and it comes back. A failure on the machine's side refunds automatically; a circuit that a machine's validator refuses is machine-side too. Only a run you asked for and got is money spent.
Codenames are what the SDK and API take. The last column is a 5,000-shot run — the size of a typical experiment — so the scale is felt, not imagined.
cost = shots × per-shot rate — a 5,000-shot run on RoRo Quantum A1 is 5,000 × 0.25 = 1,250 credits, exactly what the run record shows. Our own simulators (roro.sim.*) are free: a run there charges nothing and writes nothing to the ledger. Catalog snapshot from the live platform, September 2026; the console's live catalog is always authoritative. Organisations can carry negotiated rates on priced machines — the quote at submit is what binds.
$142.50 — a full semester of weekly simulator labs costs nothing, and every one of fifty students still sends one circuit to real hardware: under $3 per student. Each student's own 100 free credits add headroom on top.
≈ 3,100 cr — one 5,000-credit package covers a weekend that ends with real quantum results in the demo, with room to spare; the simulator work along the way costs nothing.
≈ 20,600 cr — one 25,000-credit package, with the sweep's manifests, histograms and comparison exportable straight from the lab.
The rate you see is the rate you pay, per shot, per machine. Partner hardware and partner simulators are priced from what the partner charges us; our own simulators are free — iterate and teach on them without spending a credit.
