We've added support for OpenAI's new 5.0 models in our Voice Agent API!

Available Models:

• 5.0 (gpt-5)
• 5.0 Mini (gpt-5-mini)
• 5.0 Nano (gpt-5-nano)

Implementation: Configure your chosen model in your Voice Agent settings:

{
  "type": "Settings",
  "agent": {
    "think": {
      "provider": {
        "type": "open_ai",
        "model": "gpt-5"
      }
    }
  }
}
