Pricing
Delta AI is priced in credits. A plan bundles credits at a lower per-credit price than buying them individually.
| Plan | Monthly | Credits included |
|---|---|---|
| Discovery | $25 | Matching credit value |
| Pro | $50 | Matching credit value |
| Business | $200 | Matching credit value |
Each plan includes credits equal to its monthly price, at a lower per-credit cost than a one-off top-up.
Free tier
Section titled “Free tier”A new account covers the first architecture and one service end to end, free. No card required.
That means the architecture step with its system design and overview diagram, the specification step for one service with that service’s diagram, and the implementation step for that service as a pull request. A complete vertical slice, not a preview.
Anything beyond that needs credits: a second service, a second session, or a Feature change that touches an existing service. If your balance cannot cover a run, the run is queued rather than refused, and starts on its own once credits are available.
Buying credits without a plan
Section titled “Buying credits without a plan”Credits can be bought directly, starting at $10. They never expire.
Credits bought inside a plan cost less per credit than a standalone purchase.
