I propose the integration and enhancement of KaTeX within the Open WebUI project to address bug #3930. This feature aims to provide users with a more flexible and robust configuration for rendering mathematical expressions.

Proposed Changes:

Support for Multiple Delimiters:
- Allow the use of both dollar signs ($ for inline and $$ for display) and LaTeX-style delimiters ($ and $ for inline, \[ and \] for display). This will enhance user experience by accommodating different LaTeX usage preferences.
Equation Environment:
- Introduce support for the LaTeX equation environment using \begin{equation} and \end{equation}. This feature will enable users to write numbered equations easily, improving the clarity and organization of mathematical content.
Configuration Example:
- Provide a sample configuration that demonstrates how to set up KaTeX with the proposed delimiters and equation environment. This will serve as a guide for users to implement the changes effectively.

Benefits:

This enhancement will resolve the current limitations faced by users regarding mathematical rendering in the Open WebUI, making it more versatile and user-friendly.
By supporting multiple delimiters and the equation environment, users will have greater flexibility in how they present mathematical content, catering to a wider range of use cases.

I believe that these improvements will significantly enhance the functionality of the Open WebUI project and look forward to the community's support in implementing this feature.

I believe Perplexity.ai uses the same strategy. Very effective IMHO.
