# Credits and Pricing (/docs/billing/plans)

How credits work, what a run costs, and how to get more.



Solaris AI Flow runs on credits. There are no account tiers: every account gets the full visual editor, all node types, and marketplace access. There are no subscriptions and no monthly run cap.

How credits work [#how-credits-work]

Credits are the usage currency. Every workflow run uses a base charge of 3 credits. Loops and heavier usage may reserve more, and any unused reservation is refunded.

Large run outputs [#large-run-outputs]

Every run includes 256 KB of stored node output at no extra cost. Beyond that, a run costs 1 credit for each additional 64 KB it stores. Most runs never reach the included amount and pay nothing extra; the charge only applies to runs that persist unusually large outputs.

There are three kinds of credits:

* **Purchased credits** - bought with SOL, they never expire.
* **Free monthly credits** - 50,000 credits that refresh automatically each month and roll over up to 100,000.
* **Promo credits** - earned from quests or promotions; these expire after 180 days unless a promotion says otherwise.

When a run is charged, promo credits are spent first, then free credits, then purchased credits.

Pricing [#pricing]

10,000 credits = $1. Credits are bought with a one-time SOL payment from your embedded wallet at the live SOL/USD rate. Top-up packs are 10,000, 50,000, 250,000, and 1,000,000 credits. There is no auto-renew and no card on file.

**0% platform fees during beta** - marketplace sellers keep 100% of revenue.

Earning credits [#earning-credits]

Complete setup quests to earn credits while you learn the product. Open **Quests** from the dashboard sidebar, or see [Earn Credits with Quests](/docs/billing/quests) for the current rewards and what counts.

Guardrails [#guardrails]

For safety and abuse prevention there are still some operational limits (for example, how many runs execute at once and per-run output and time bounds). These apply to everyone and are not a paywall.
