What is the issue?

When I display content containing inline LaTeX-style math expressions in the Ollama GUI, the expressions are not rendered. Instead, the GUI shows the raw source text, including $...$, backslashes, and commands such as \rightarrow.

For example, content like:

$C \rightarrow S \rightarrow L \rightarrow P \rightarrow A$

and

$Why \rightarrow What \rightarrow How \rightarrow Where \rightarrow When$

is displayed literally in the chat/output view, instead of being rendered as formatted inline math or symbolic arrows.

This breaks readability and makes educational or technical content much harder to follow.

Expected behavior

The GUI should do one of the following consistently:

Render inline LaTeX/math expressions correctly when enclosed in $...$, including commands such as \rightarrow. If LaTex/math rendering is not supported, gracefully fall back to readable markdown/plain text handling rather than exposing raw escape syntax in a visually broken way.

Actual behavior

The GUI displays the raw expression text literally, including:

Dollar signs Backslashes LaTex commands such as \rightarrow

As a result, expressions that should appear as arrow-based sequences are shown as unrendered source code inside normal prose.

Example output

YATAY EKSEN: $C \rightarrow S \rightarrow L \rightarrow P \rightarrow A$

DİKEY EKSEN : $Why \rightarrow What \rightarrow How \rightarrow Where \rightarrow When$

Observed result The UI displays the literal source text, including \rightarrow, instead of rendering arrows.

Impact This is especially problematic for:

  • technical documentation
  • educational material
  • architecture/framework explanations
  • mathematical or symbolic notation in responses

It reduces clarity and makes the GUI feel inconsistent with markdown-capable chat interfaces.

Possible cause

This looks like one of the following:

  • inline math is not supported in the markdown renderer
  • math syntax is being escaped or sanitized before rendering
  • the renderer supports markdown but not KaTeX/MathJax-style inline expressions
  • backslash-based commands are passed through as plain text without fallback formatting

Suggested fix

Either:

  • add proper inline/block math rendering support, or
  • detect unsupported LaTex syntax and convert common commands such as \rightarrow into readable Unicode equivalents like →

extent analysis

TL;DR

The most likely fix is to add support for inline math rendering or implement a fallback to convert LaTeX commands into readable Unicode equivalents.

Guidance

  • Verify if the markdown renderer used in the Ollama GUI supports inline math expressions, and if not, consider adding support for KaTeX or MathJax.
  • Check if the math syntax is being escaped or sanitized before rendering, and adjust the sanitization rules to allow for LaTeX commands.
  • Implement a fallback mechanism to convert common LaTeX commands, such as \rightarrow, into readable Unicode equivalents, like →.
  • Review the Ollama GUI's documentation and configuration to ensure that inline math rendering is enabled and properly configured.

Example

// Example of converting LaTeX command to Unicode equivalent
const latexCommand = "\\rightarrow";
const unicodeEquivalent = "→";
const renderedText = `$C ${latexCommand} S ${latexCommand} L ${latexCommand} P ${latexCommand} A`.replace(latexCommand, unicodeEquivalent);
console.log(renderedText); // Output: $C → S → L → P → A$

Notes

The suggested fix assumes that the Ollama GUI uses a markdown renderer that can be extended or modified to support inline math expressions. If the renderer does not support this, alternative solutions, such as using a different renderer or implementing a custom parsing mechanism, may be necessary.

Recommendation

Apply a workaround by implementing a fallback mechanism to convert common LaTeX commands into readable Unicode equivalents, as this can provide a temporary solution to improve readability until full inline math rendering support can be added.
