We're excited to announce an easier way to use Cartesia's Text-to-Speech models inside Deepgram's voice agent – Deepgram-managed Cartesia models.

Similar to our managed LLM's, simply specify Cartesia as your model provider and the correct model name to get started instantly. No Cartesia account creation, setup, or payments are required – this feature is included as part of Deepgram's Standard pricing tier.

For detailed information, please refer to our TTS documentation.

We've added support for Anthropic's new Claude Haiku model in our Voice Agent API!

Implementation:

Configure your chosen model in your Voice Agent settings:

{
  "type": "Settings",
  "agent": {
    "think": {
      "provider": {
        "type": "anthropic",
        "model": "claude-haiku-4-5"
      }
    }
  }
}
