# Overview

> Documentation for Overview (ExtNsT3AF).

## Purpose

Explain what T3Planet Credits is and when to use it.

## What it is

T3Planet Credits is T3Planet’s managed AI access in AI Foundation (`ns_t3af`):

* You do **not** need your own OpenAI / Anthropic / similar keys for billable AI
* AI Foundation sends those calls to T3Planet
* Usage is counted in **credits**

## Requirements

* A valid T3Planet license (`EXT:ns_license`)
* AI Foundation (`EXT:ns_t3af`) installed and active

## What’s covered

When Credits is active, it can cover:

* Text completion
* Streaming
* Embeddings
* Text-to-speech (TTS)
* Image generation

## Own API Keys vs Credits

|               | Own API Keys        | T3Planet Credits                 |
| ------------- | ------------------- | -------------------------------- |
| Your API keys | Required            | Not used for AI calls            |
| Who runs AI   | Vendor API (direct) | T3Planet                         |
| Providers UI  | Shows provider list | Hides list; shows Credits panels |
| AI Usage id   | Your provider id    | `t3planet_credits`               |

## Selected vs Active

* **Selected** — Credits card chosen; token not yet issued. Complete
  Activate to finish setup.
* **Active** — License available and token ready. AI can run through Credits.

## When to use Credits

* You want AI without managing vendor keys
* You want one shared credit pool

Use Own API Keys when you already manage vendor keys yourself.

## What uses credits

Credits are used when Credits is **active** and an AI Foundation AI call
completes successfully through T3Planet.

Opening modules or only switching the card does **not** use credits.

## Switch modes

**Turn on**

1. Open AI Foundation > AI Providers
2. Choose T3Planet Credits
3. Click Activate if shown
4. Success message → page reload

**Turn off**

1. Choose Your Own API Keys
2. Confirm if asked
3. Provider list appears again

<Tip>
  Switching off does not delete the stored Credits token. It only turns Credits
  off.
