Persona & model

Your agent's persona is how it presents itself to visitors, and its model is the AI that generates its replies. Both live in the Persona card on the agent page.

Persona

The persona has two parts:

• Name — how the agent refers to itself in conversation (for example, "Aria"). If you leave it blank, the project name is used. This is the name baked into the agent's identity; the label shown in a specific chat header is set per deployment in Appearance.
• Avatar — the face shown on the chat welcome screen and beside the agent's replies. Upload a square image, or leave it unset to use an automatically generated placeholder.

To change either, open the agent page and click Edit persona. Update the name, swap the avatar, and save.

Model

The model is the AI that reads your knowledge and writes the agent's answers. Every agent has a model setting, and by default it uses the latest system model — Lorito keeps this pointed at a strong, balanced model and updates it for you as newer versions become available. You don't have to choose anything to get a good result.

Choosing a different model

Open Edit persona and pick a model from the dropdown. Models are grouped by provider, and each option shows a short hint about its trade-offs — some are tuned for speed and lower cost, others for higher quality.

What changing the model does:

• It takes effect on the next message the agent answers. Existing conversations aren't reprocessed.
• It applies to this agent only. Other agents and projects keep their own settings.
• It does not change your knowledge base or system prompt — only which AI generates the replies.

If you ever want to go back, reopen the dropdown and select the latest model in its group, or pick the one marked as the current default.
