# Workspace default settings The **Workspace default settings** menu allows to configure default parameters for workspaces. These settings ensure consistent behavior for data processing, privacy protection, and synthetic data generation. Below is a detailed explanation of the available options. {% hint style="info" %} These defaults may vary by deployment/version; your admin may expose a subset. {% endhint %} ## Access the workspace default settings Note that user should be an **Owner** or **Editor** to access Workspace Default Settings. 1. Go to **Edit workspace** via **Saved workspaces** panel or from **Configuration panel**. 2. Select **Default settings**. ## **How to modify settings** 1. Access the **Workspace default settings** menu. 2. Modify the required values directly. 3. **Confirm** changes to apply them to the workspace. ## **Configuration options** Below is an overview of the default settings and their functionalities. {% hint style="info" %} `pii_model_settings` controls models used for PII scanning/mocking. `default_text_processor_model_settings` uses the same structure (engine/models/gpu), but applies to text processing defaults. {% endhint %} ### Consistency (seed) settings For more information please see [Configure to use other NLP models (limited support)](https://docs.syntho.ai/configure-a-data-generation-job/configure-column-settings/duplicate/automatic-pii-discovery-and-de-identification-in-free-text-columns#configure-to-use-other-nlp-models-limited-support). ### AI synthesis (performance) | **Parameter** | **Default** | **Possible Values** | **Description** | | -------------------------------- | ------------ | ------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `n_parallel_pipeline_processes` | 1 | Any integer ≥ 1 | Number of column-level processing tasks that run in parallel.
