Credits and plans
Understand reservations, monthly credits, compute limits, and subscriptions.
What a credit pays for
One credit represents US$0.001 in the engine's pricing. Model input, cached input, output, compute, reviews, and proof checks have configured rates. Knowledge search and embeddings are not billed to researchers.
The quote is a spending ceiling, not a promise that all reserved credits will be consumed. A mission reserves its budget atomically before starting. It settles actual spending and returns the unused amount after completion.
Current plan limits
| Limit | Free | Pro | Advanced |
|---|---|---|---|
| Monthly credits | 2000 top-up | 30000 added | 120000 added |
| Parallel agents | 10 | 50 | 200 |
| Concurrent missions | 1 | 3 | 10 |
| Steps per agent | 25 | 150 | 600 |
| Concurrent CPU jobs | 4 | 25 | 100 |
| Largest machine | standard-1 | standard-2 | standard-4 |
| Run timeout | 10 min | 2 h | 12 h |
| Storage | 1 GB | 25 GB | 200 GB |
| Discovery delay | 72 h | 6 h | 0 h |
These values come from config/engine.config.ts. Queue priority increases from Free to Pro to Advanced; job availability still depends on shared capacity.
Subscription prices
The billing configuration lists Pro at US$30 per month or US$300 per year, and Advanced at US$100 per month or US$1000 per year. Configured Pro prices include a 15-day trial. Organization prices are per member at the same personal price.
The configured top-up packages are Starter (10000 credits for US$9.99), Basic (50000 plus 5000 bonus credits for US$39.99), and Pro (200000 plus 40000 bonus credits for US$149.99). Use the checkout for the price and terms applicable to a purchase.
Free credits and changes
Free monthly grants require a verified email and top up the free allowance. A per-research monthly guard limits free-plan spending across free accounts; purchased credits are not subject to that free-credit cap.
Review the plan-change preview before confirming. Scheduled changes keep the current plan active through the relevant billing period. Billing and cancellation terms are available in the legal documents.
