# AI Providers

> AI Providers for EXT:ns_t3af (T3AF).

## Purpose

Connect TYPO3 to AI models. This is the **most important** T3AF screen. Without at least one working provider, no AI feature runs.

**Path:** T3AF → AI Providers

## Add a provider (step by step)

1. Click **Add provider**
2. Choose vendor (OpenAI, Anthropic, Gemini, Azure, Mistral, DeepSeek, xAI, custom, Ollama)
3. Paste API key (encrypted on save)
4. Select model
5. Click **Test connection**
6. Enable **Default** on exactly one provider

## Supported vendors

OpenAI, Anthropic (Claude), Google Gemini, Azure OpenAI, Mistral, DeepSeek, xAI, Custom OpenAI-compatible endpoints, and Ollama (local).

## Capabilities

Pick a model that supports what you need. **Test connection** validates your choice.

* **Chat** — Text generation
* **Streaming** — Live response display in the backend
* **Embeddings** — Search and similarity features
* **Vision** — Image analysis
* **Tool use** — MCP agent workflows

## Multiple providers — when and why

**Dev and live** — Two provider rows with different API keys per environment.

**Cost saving** — Cheap model as global default; premium model assigned in [AI Features](/en/latest/en/latest/ExtNsT3AF/AIFeatures/Index) for important tasks.

**EU hosting** — Mistral or Azure in an EU region for data residency requirements.

## Billing modes

**Your Own API Keys (BYOK)** — Pay the vendor directly. This is the default mode.

**T3Planet Credits** — Toggle in AI Providers, then click **Activate**. See [T3Planet Credits](/en/latest/en/latest/ExtNsT3AF/T3PlanetCredits/Index).

## Troubleshooting

**Test fails** — Check key, model ID, and firewall (outbound HTTPS must be allowed).

**Rate limit** — Wait or upgrade your vendor plan.

**Vision returns empty** — Use a vision-capable model (for example GPT-4o with vision).

**Module works but child extension fails** — Check [AI Features](/en/latest/en/latest/ExtNsT3AF/AIFeatures/Index) for per-task overrides.

## Security

* Rotate keys every 90 days
* Use one key per environment (dev, staging, live)
* Restrict access via [AI Permissions](/en/latest/en/latest/ExtNsT3AF/Configuration/AIPermissions/Index)
* Never commit API keys to Git
