# Agent Settings: LLM Selection

![LLM Selection dialog listing OpenAI models such as chat-latest, gpt-4o-mini, gpt-5, and gpt-5.2-pro in a searchable grid, with gpt-4o-mini highlighted as selected](/images/docs/os/agent-settings/agent_settings_llm_selection.webp)

## Overview

The LLM Selection dialog picks the exact model an agent uses from a chosen provider. Its subtitle reads: "Choose your preferred LLM from the available provider to tailor your experience." The dialog opens after you click a provider card (for example, OpenAI) on the LLM panel.

Each model appears as a card with the provider's icon and the model name. The agent's current model is highlighted (the screenshot shows `gpt-4o-mini` selected from the OpenAI list, which includes models such as `chat-latest`, `gpt-4.1`, `gpt-4o-mini`, `gpt-5`, and the `gpt-5.x` family with mini/nano/pro variants). The available models are served by the platform for the selected provider, so the list you see depends on your organization's configuration.

To reach this dialog, open the **Edit Agent** modal, stay on the **Configurations** tab group, select **LLM** in the left sidebar, then click a provider card.

## Target Audience

**Administrator** | **Agent Builder**

## Dialog Reference

#### Search
A search box at the top filters the model grid by name as you type — useful when a provider exposes a long model list.

#### Model cards
One card per model offered by the selected provider. Clicking a card immediately assigns that provider and model to the agent — the platform saves the agent's `llm_provider` and `llm_name` and shows an "LLM updated successfully" confirmation (or an error message if the update fails). The currently assigned model is outlined so you can see the active choice at a glance.

#### Close (X)
Closes the dialog without changing the agent's model. You can also return to the provider grid to pick a different provider first.

## How to Use

#### Step 1: Open the LLM panel
Open the **Edit Agent** modal, keep **Configurations** selected, and click **LLM** in the sidebar.

#### Step 2: Pick a provider
Click the provider card whose models you want (for example, OpenAI, Anthropic, or Google). The LLM Selection dialog opens with that provider's models.

#### Step 3: Find the model
Type in the **Search** box to filter the grid if the list is long.

#### Step 4: Select the model
Click the model card. The agent is updated immediately and a success message confirms the change — there is no separate save step. Every subsequent reply from the agent is generated by the newly selected model.
