# Subscription

> Hercules subscription plans include hosting, AI credits, and cloud credits.

Your Hercules Subscription tier determines which Hercules platform features you can access. Each tier also includes a certain amount of <a href="/platform/billing/ai-credits">AI Credits</a> and <a href="/platform/billing/cloud-credits">Cloud Credits</a>.

### What features are available in each plan?

See our [pricing page](https://hercules.app/pricing) for a complete comparison of features in each plan.

### What are AI credits?

AI credits power the Hercules AI Agent. You use AI Credits every time you talk to Hercules. Your subscription plan includes a monthly allocation of AI credits. You can buy more credits anytime. Learn more in [AI Credits](/platform/billing/ai-credits).

### What are cloud credits?

Cloud credits (your Cloud Balance) cover Hercules Cloud hosting usage beyond your subscription plan's included limits. It also covers any AI inference triggered inside your published app through the Hercules AI Gateway. Learn more in [Cloud Credits](/platform/billing/cloud-credits).

### How do subscription upgrades work?

When you upgrade:

* You pay only the **prorated difference** between your current and new plan
* You immediately receive the **prorated AI credit difference** between your current and new plan, not the full amount
  * These AI credits are valid for **28 days** from the grant date
* Your billing cycle does **not** reset. It stays anchored to your original sign up date

<Callout type="info">
  <strong>Note:</strong> Upgrades only take effect immediately if your new plan is more expensive
  than your current one. If the new plan costs less (even if it's a higher tier), it is considered a
  downgrade.
</Callout>

### How do subscription downgrades work?

Downgrades are scheduled to take effect at the **start of your next billing cycle**. You keep your current plan until then.
