# AI Model Usage

> Learn how to use and configure different AI models

### What models is AskUI using?

AskUI uses a **layered system of AI models,** each with a distinct role in understanding, executing, and interacting with user interfaces. Here's how we classify and use them:

1. **Locator Models** (Locators)
   1. Locator models identify and interact with UI elements on the screen.
2. **Query Models** (Asks)
   * Responsible for answering user queries or generating intelligent responses.
3. **Action Models** (act command) (Multi Step)
   * Responsibilites
     * Goal to → Planning
     * Delegate Locator Models
     * Delegate Query Models
     * Reflection of Errors
   * UI-Tars
   * Computer-Use

| **Model Type**     | **Model Name**   | **Purpose**                            | **Teachable** | **Online Trainable** |
| :----------------- | :--------------- | :------------------------------------- | :------------ | :------------------- |
| Locator            | UIDT-1           | Locate elements & understand screen    | No            | Partial              |
| Locator            | PTA-1            | Convert prompts into one-click actions | No            | Yes                  |
| Query              | GPT-4            | Understand & respond to user queries   | Yes           | No                   |
| Query              | Gemini 2.5 Flash | Understand & respond to user queries   | Yes           | No                   |
| Query              | Gemini 2.5 Pro   | Understand & respond to user queries   | Yes           | No                   |
| Query              | Computer Use     | Understand & respond to user queries   | Yes           | No                   |
| Large Action (act) | Computer Use     | Plan and execute full workflows        | Yes           | No                   |
| Large Action (act) | UI-Tars          | Plan and execute full workflows        | Yes           | No                   |
