[FEAT]: Latex Math Formula Render

[JesseM1024]

What would you like to see?

Currently it can render code blocks correctly but it cannot render latex formulas. Sometimes the readability of Latex related responses are quite low. For example:

Hi I can help with implementing this

@Dljdd this would be incredibly useful; thank you.

Just lending my vote for this as a high-value feature, while recognizing it's likely to be somewhat tedious to implement. Some of the LaTeX render failures are simply bad LLM output, but many of the cases not captured by AnythingLLM are quite clearly valid latex blocks.

It appears that the LaTeX parser being used does not support the delimiters \( ... \) and \[ ... \] that the LLM outputs. Here's a GitHub issue I found asking for a workaround for that package: markdown-it-katex Issue #10 -- No idea why the issue was closed without any resolution. 🥴

Maybe we can just fork that library and add more delimiters to cover this? Not sure, but that is basically the root cause here. The main issue is that [] and () are valid markdown, so they can conflict

Edit:

Can someone copy-paste some text output that is not rendering in AnythingLLM so i can test this?

First chat raw - using $$ notation as well as $

Sure! A Taylor series of a function f(x) centered at a point a can be represented in LaTeX as:

$$f(x) = \sum_{n=0}^\infty \frac{f^{(n)}(a)}{n!}{(x-a)}^n$$

Here, $f^{(n)}(a)$ represents the nth derivative of f(x) evaluated at x = a, and n! represents the factorial of n. The summation symbol $\sum$ indicates that we are summing all the terms from n = 0 to infinity.

Using block notation

Sure! Here is the same Taylor series using the LaTeX notation that uses \[...\] and \(...\):

\[f(x) = \sum_{n=0}^\infty \frac{f^{(n)}(a)}{n!}{(x-a)}^n\]
In this case, we used \[ and \] to enclose the equation, and \( and \) to enclose the variables and symbols within the equation.
