## Use Deepgram's Managed Cartesia TTS Models

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](/guides/self-hosted-deployments-3-voice-agent-tts-models#deepgram-managed-cartesia-tts-models).

Similar to our [managed LLM's](/guides/self-hosted-deployments-3-voice-agent-llm-models#supported-llm-providers), 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](https://deepgram.com/pricing).

For detailed information, please refer to our [TTS documentation](/guides/self-hosted-deployments-3-voice-agent-tts-models).

## 🤖 Claude Haiku 4.5 LLM Support

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:

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