Questions & Answers
Credits are Coda's currency for AI chat usage and quantum hardware jobs. 1 credit = $1.00. New accounts get 2 free credits when they sign up. Free credits are used first, then any paid monthly credits from Pro or Ultra.
No. Paid credits roll over across billing cycles and never expire. They accumulate until you use them.
On Lite, Pro, and Ultra you can enable optional pay-as-you-go billing for real QPU jobs after credits are depleted. Overage is tracked and billed at the end of your billing period. To keep using AI chat after credits run out, upgrade or wait until your next monthly credit grant on a paid plan.
No. Lite includes pay-as-you-go QPU access once you enable overage billing for real hardware. Circuit simulation itself does not charge QPU fees—Lite supports CPU simulation up to 16 qubits, and Pro+ unlocks GPU-accelerated simulation up to 29 qubits. AI chat usage still consumes credits on every plan.
Braket QPU jobs are priced with a base task fee plus a per-shot fee. IBM jobs are quoted from an estimated circuit runtime instead of a fixed per-shot rate.
| Hardware | Base Fee | Per Shot |
|---|---|---|
| Simulator | Free | Free |
| IonQ Forte / Forte Enterprise | $0.60 | $0.16 |
| IQM Garnet | $0.60 | $0.0029 |
| IQM Emerald | $0.60 | $0.0032 |
| Rigetti Cepheus-1-108Q | $0.60 | $0.00085 |
| AQT IBEX Q1 | $0.60 | $0.047 |
| IBM Quantum | Quoted per job from circuit runtime | |
Yes. Before confirming any quantum job, you'll see an estimated cost in credits based on your chosen hardware and shot count (or, for IBM, the estimated runtime).
A shot is a single execution of your quantum circuit. Because quantum results are probabilistic, you typically run many shots (e.g., 1000) to get statistically meaningful results. More shots mean more accurate results but higher cost on Braket devices that bill per shot.
