Mathematical formulas fail to render correctly in the chat interface

[zzzongzii]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In modes such as chat/agent/plan/inline chat, the mathematical formulas output by the model cannot be rendered correctly; they always appear as plain text, making it completely incomprehensible to users

Steps to Reproduce

1. Let the model output some mathematical formulas and symbols
2. All plain text, not rendered correctly

Expected Behavior

The formula is correctly rendered in a readable form

Gemini 3.0 pro, Codex, Sonnet 4.5

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. This isn’t a bug: LaTeX rendering is currently not supported in chat.

There’s a feature request for full support here:

LaTeX rendering in chat

It’d be nice to add LaTeX rendering to the chat interface. It’s already using Markdown, so probably it’s easy to implement a Mathjax plugin. For example, I use Cursor to discuss papers (previously transformed to .mdd using Nougat), and it would be nice to have the GPT-4 replies with LaTeX rendering in the chat.

Alright, thank you for your reply. Shouldn’t this be a basic feature? Otherwise how can these models’ mathematical reasoning abilities be leveraged?
