# How to add LLM Credits

Use **Additional LLM Credits** to increase the monthly credit allowance on an active **Base LLM API** subscription. Each credit equals CHF 1 of inference capacity. Top-ups renew automatically each month unless you cancel the subscription.

---

## Prerequisites

Before purchasing a top-up, make sure you have:

- An active Sunrise portal account with permission to make purchases
- An active **Base LLM API** subscription
- The **Sunrise API Key** for the Base LLM API you want to credit

!!!info
Additional LLM Credits apply to one Base LLM API subscription. All API keys on that subscription share the same credit pool, including any credits you add through a top-up.
!!!

If you do not have a Base LLM API subscription yet, purchase one first from **Products** in the [Sunrise Console](https://portal.ai.sunrise.ch). See [Subscription Plans](../subscriptions/index.md) for plan details.

## Add a recurring top-up

Sign in at [https://portal.ai.sunrise.ch](https://portal.ai.sunrise.ch).

### 2. Purchase Additional LLM Credits

1. Open **Products** from the left navigation (or click **Add Subscription** from the Dashboard).
2. Find **Additional LLM Credits** in the Model Service category.
3. Choose how many credits to add each month. Each credit costs **CHF 1** (excl. VAT).
4. Click **Add to cart**, then **Proceed to Checkout**.
5. Complete checkout and confirm your order.

For general checkout steps, see [Buy a Subscription](../../getting-started/buy-a-subscription.md).

### 3. Open Resource Groups

Navigate to **Resource Groups** in the left-hand menu and open your **Sunrise Model Service** resource group. Expand the **Subscriptions** list and find **Additional LLM Credits** with status **Ordered**.

### 4. Provision the top-up

1. Click **Provision Service** on the **Additional LLM Credits** row.
2. In the **Provision service** pop up, select the **LLM API** you wish to add these credits to from the dropdown.
3. Click **Provision**.

The additional credits are added to the selected Base LLM API subscription.

## What happens next

- The top-up credits are available on your Base LLM API subscription for the current billing period.
- The **Additional LLM Credits** subscription **renews automatically** each month and adds the same number of credits again.
- Credits are deducted based on each model's input and output token pricing per 1M tokens.
- Credits are non-transferable and expire at the end of each billing period.

---

## One-time top-up

If you only need extra credits for a single month:

1. Purchase **Additional LLM Credits** and provision it against your Base LLM API key, as described above.
2. [Cancel the Additional LLM Credits subscription](how-to-cancel-a-model-service-subscription.md).

You can use the purchased credits for the remainder of that billing period. The top-up will not renew in the following month.

## Notes

!!!info Good to know
- You must provision the top-up before the credits apply to your Base LLM API. Purchasing alone does not add credits until provisioning is complete.
- You can purchase multiple **Additional LLM Credits** subscriptions if you need to increase allowance further. Provision each one against the same Base LLM API key.
- Monitor usage against your combined credit allowance (Base LLM API credits plus any active top-ups).
