Providers represent connections to AI services. Each provider stores an adapter type, optional endpoint, encrypted credentials, models, and capability flags. Path: T3AF > AI Providers Follow this interactive walkthrough, then continue with the details below. AI Providers list with configured vendors, models, status, and actions AI Providers list — configured adapters, models, connection status, and default provider. Without at least one working provider, no AI feature runs.

​
Adding a provider

  1. Open T3AF > AI Providers.
  2. Click Add provider.
  3. Fill in the required fields:
  • Display name — Friendly label for your team (for example OpenAI production).
  • Adapter type — Vendor protocol (OpenAI, Anthropic, Gemini, Azure, Mistral, DeepSeek, xAI, Ollama, or custom OpenAI-compatible).
  • API key — Cloud vendors need a key. Leave empty for local Ollama.
  • Model ID — Completion model (for example gpt-4o-mini).
  1. Optionally set the endpoint URL, embedding model, capabilities, temperature, and pricing fields.
  2. Click Save.
  3. Enable Default on exactly one provider.
For first-time setup, use Quick Setup in the T3AF module header. It walks through provider creation with fewer decisions.

​
Testing a connection

After saving a provider, click Test connection to verify the setup. The test calls the provider API and reports:
  • Connection status (success or failure)
  • Error details on failure
  • Model / capability hints when the adapter can list them
Self-hosted endpoints (such as Ollama) must be reachable from the TYPO3 server. Typical causes of a failed test:
  • Wrong host or port in Endpoint URL (default http://localhost:11434 for Ollama)
  • Docker/network isolation between PHP and the model host
  • Outbound HTTPS blocked for cloud vendors
Local adapters usually do not need an API key. Cloud adapters do.
If your server reaches the internet only through a corporate proxy, configure TYPO3 HTTP settings: config/system/additional.php

​
Editing and deleting providers

  • Click a provider row to edit its settings in the drawer.
  • Use Test connection after rotating an API key or changing the model.
  • Use Delete to remove a provider. Features that pointed at that provider fall back to the global default (or fail until another provider is assigned).
Deleting the only default provider leaves child extensions without a global fallback. Set another provider as Default first.

​
Supported adapters

Built-in and discovered adapters include:
  • symfony.openai — OpenAI
  • symfony.anthropic — Anthropic Claude
  • symfony.gemini — Google Gemini
  • symfony.mistral — Mistral AI
  • symfony.ollama — Local Ollama
  • symfony.openrouter — OpenRouter
  • nst3af.openai_compatible — Custom / OpenAI-compatible endpoints
  • Additional Symfony AI bridges when their Composer packages are installed (for example Azure, DeepSeek, xAI)
Custom adapters: Custom AI Providers.

​
Capabilities

Pick a model that supports what you need. Test connection helps validate the 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 — Separate rows with different API keys per environment. Cost saving — Cheap model as global default; premium model assigned in AI Features for important tasks. EU hosting — Mistral or Azure in an EU region for data residency requirements.

​
Provider fields

Fields below map to the AI Providers drawer and the tx_nst3af_provider table.

​
Required

​
Connection

​
Optional configuration

​
Governance and status

Optional pricing (pricing_input_per_1m, pricing_output_per_1m, pricing_currency, cost_center), retention overrides, dashboard analytics flags, and read-only status fields (last_status, last_status_at, last_status_message, last_used_at) support monitoring and cost tracking. Status fields update after Test connection and live requests.

​
Troubleshooting

Test fails — Check the API key, model ID, endpoint URL, and outbound HTTPS/firewall rules. Rate limit — Wait or upgrade the 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 for per-task overrides.

​
Security

  • Rotate keys every 90 days
  • Use one key per environment (dev, staging, live)
  • Restrict access via AI Permissions
  • Never commit API keys to Git
