Good to know
- You pay the provider directly; Tantra does not mark up usage.
- Exactly one LLM provider is your default at a time.
- Removing the default, or having no valid default, falls campaign personalization back to the plain template.
- The template editor's Generate and Enhance buttons use Tantra's built-in AI, not this key.
Frequently asked questions
Who pays for OpenRouter usage?
- You do. Tantra passes personalization requests through, but the OpenRouter bill goes to your own account.
Can I have more than one active default provider?
- No. Exactly one LLM provider is the default at a time.
What happens if I remove my default provider?
- Campaign personalization falls back to the plain template until a new default is set.
