# Model and behavior settings

> The Settings pages that control which model answers, how much context it sees, and conversation limits.

Your chatbot's **Settings** section (under **Advanced** in the sidebar)
controls the machinery behind answers. Most chatbots work well on the
defaults; this page explains each knob for when you need it.

## Settings → General

| Setting                                                                   | What it does                                                                                                                                                                                                                                                              |
| ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Description**                                                           | An internal note about this chatbot, for your team.                                                                                                                                                                                                                       |
| **Support Email**                                                         | The reply-to address on emails SiteGPT sends to your visitors (like OTP verification). Falls back to your account email. Escalation and lead notification recipients are set in [Human Support](/docs/features/human-support) and [Leads Settings](/docs/features/lead-collection). |
| **GPT Model**                                                             | The model that writes answers: **GPT-4.1 Mini** (default, fast) or **GPT-4.1** (strongest). GPT-4.1 answers draw from your GPT-4.1 message quota; see **Usage**.                                                                                                          |
| **Number of History Messages To Be Considered**                           | How many previous messages the chatbot re-reads when answering. Raise it for long, multi-step conversations; keep it low for one-shot Q\&A.                                                                                                                               |
| **Limit Messages Per Conversation** and **Max Messages Per Conversation** | Cap a single conversation's length. Useful against abuse and runaway usage.                                                                                                                                                                                               |
| **Enable Page Context Awareness**                                         | Lets the chatbot know which page of your site the visitor is on, so "does this apply here?" style questions work.                                                                                                                                                         |
| **Disable lead notifications**                                            | Stops the email that is sent for each new lead.                                                                                                                                                                                                                           |
| **Disable smart follow up questions**                                     | Turns off AI-generated follow-up suggestions. See [followups](/docs/features/conversation-followups).                                                                                                                                                                          |

## Settings → Advanced

| Setting           | What it does                                                                                                                                                                                                          |
| ----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **TopK**          | How many passages of your content are retrieved per answer. Raising it gives the model more material at the cost of focus.                                                                                            |
| **CSS Selectors** | Site-wide default selectors to strip when crawling, for example `header, .footer, #nav`. Changes apply when links are retrained. Per-import selectors are in [scrape options](/docs/content/website-links#scrape-options). |

## Chat modes

**Settings → Chat Modes** decides who answers first:

* **AI**: the chatbot answers, and visitors can escalate to your team when
  [human support](/docs/features/human-support) is enabled.
* **Agent**: every conversation starts with a human; the AI stays out of the
  way. Use this when you want SiteGPT as a plain live-chat inbox.

You can also take over any single conversation as a human from
[Chat History](/docs/navigating-your-chatbot/chat-history), whatever the mode.

## Webhooks

**Settings → Webhooks** sends conversation events to your own endpoints, on
plans and add-ons that include webhooks. See
[Webhooks](/docs/developers/webhooks) for payloads and setup.

## Danger zone

**Delete Chatbot** at the bottom of Settings permanently removes the chatbot,
its content, and its conversations. See
[Delete your chatbot](/docs/navigating-your-chatbot/delete-chatbot).
