AI Providers

AI providers power the intelligence behind your avatars. All model configuration is managed in the dashboard – no code changes required.

Managed Models (included)

Avatarium hosts these models on your behalf. Select one in Dashboard → Avatar Settings → Brain.

Standard models:

• Claude Haiku (claude-haiku-4-5-20251001) – fast, cost-efficient

Premium models:

• Claude Sonnet (claude-sonnet-4-6) – more capable, nuanced responses

Managed models are billed per conversation minute from your credits.

Bring Your Own Key (BYOK)

BYOK is free for every account: use your own API keys from Anthropic, OpenAI, Google, or Groq. Your tokens are billed directly by the provider.

See the BYOK Guide for setup instructions.

External Brain

Connect your avatar to any OpenAI-compatible endpoint – your own fine-tuned model, OpenRouter, or a self-hosted instance.

See Brain Configuration for details.
