# Supplier-Specific AI Model for Field and Table Extraction
In the tools section of the **Validation screen**, you can choose the AI model used for **Field Extraction** and **Table Extraction**.\
The selected **AI model** is applied to all documents for the current supplier only.
To change the model, open the options menu by clicking the **three dots** on the right side of the screen, then choose one of the available models:
* **Full** – Costs 2 tokens
* **Fast** – Costs 1 token
* **Turbo** – Costs 1 token
If the **field extraction** or **table extraction** results are not satisfactory, try switching to another model to improve accuracy.
To configure the AI model **globally for suppliers without a custom model** or to **manage which model is active for each supplier**, please refer to the corresponding documentation [**here**](/administration-and-setup/settings/document-processing/classification-and-extraction/ai-model.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.docbits.com/end-user-and-partner-section/end-user-section/validation-screen/supplier-specific-ai-model-for-field-and-table-extraction.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
