## Basic Settings

Start by configuring your Agent’s identity and default behavior.

* **Model Name** — Options include:
  * GPT-4
  * GPT-4 Turbo

  * GPT-3.5
  * GPT-3.5 Turbo\
    *Note: Latency and performance may vary by model.*

* **Webhooks** — Add one or more webhooks to stream conversation data in real time.
* **Actions** — Assign specific Actions the Agent can perform (e.g., send SMS, update lead, transfer call).

  * Lower = more deterministic.
  * Higher = more creative.
* **Conversation Speed** — Controls how quickly the Agent interrupts:
  * Lower = slower to interrupt.
