 | Setting<br/>(python.analysis.) | Default | Description |
 | --- | --- | --- |
 | typeCheckingMode | off | Specifies the level of type checking analysis to perform. <br> Available values are `off`, `basic`, and `strict`. <br> When set to `off` no type checking analysis is conducted; unresolved imports/variables diagnostics are produced. <br> When set to `basic` non-type checking-related rules (all rules in `off`), as well as basic type checking rules are used. <br> When set to `strict` all type checking rules at the highest severity of error (including all rules in `off` and `basic` categories) are used. |
+| languageServerMode | default |  Offers predefined configurations to optimize Pylance's performance based on the development needs. <br> Available values are `default` and `light`. <br> When set to `default`, the language server delivers sufficient functionality for most machines without overloading the system. <br> When set to `light`, it enables a lightweight, memory-efficient setup. This mode disables various features to make Pylance function more like a streamlined text editor, and it's ideal for those who do not require the full breadth of IntelliSense capabilities and prefer Pylance to be as resource-friendly as possible. <br> Default setting values are overriden to the following by each mode:  <table> <tr> <th>Setting</th> <th>`light` mode</th> <th> `default` mode </th> </tr> <tr> <td>python.analysis.exclude</td> <td> ["**"]    </td> <td> [] </td>  <tr> <td>python.analysis.useLibraryCodeForTypes</td> <td>false</td> <td>true</td> <tr> <td> python.analysis.enablePytestSupport  </td> <td>false</td> <td>true </td>  <tr> <td> python.analysis.indexing </td> <td>false</td> <td>true </td></tr> </table> |
 | diagnosticMode | openFilesOnly | Specifies what code files the language server analyzes for problems. <br> Available values are `workspace` and `openFilesOnly`. |
 | include | [] | Paths of directories or files that should be included in analysis. <br> If no paths are specified, Pylance defaults to the directory that contains the workspace root. <br> Paths may contain wildcard characters such as `**` (a directory or multiple levels of directories), `*` (a sequence of zero or more characters), or `?` (a single character). |
 | exclude | [] | Paths of directories or files that should not be included in analysis. <br> These override the directories listed under the `python.analysis.include` setting, allowing specific subdirectories to be excluded. <br> Note that files listed in this `exclude` setting may still be included in the analysis if they are referenced/imported by source files that are not in the excluded list. <br> Paths may contain wildcard characters such as `**` (a directory or multiple levels of directories), `*` (a sequence of zero or more characters), or `?` (a single character). <br> If no exclude paths are specified, Pylance automatically excludes the following: `**/node_modules`, `**/\_\_pycache\_\_`, `.git` and any virtual environment directories. |
