[Feature]: Render LaTeX/math in chat for research workflows

[dkritarth]

Problem / use case

When an assistant returns LaTeX, T3 Code currently shows the TeX source as ordinary text instead of rendering the mathematics. This makes scientific and technical responses difficult to read, check, and reuse.

I encountered this while using T3 Code for an ensemble weather-forecasting research workflow. The attached screenshot shows equations such as \frac, \sum, \operatorname, and \begin{aligned} displayed literally in the chat instead of as formatted math.

Actual behavior

Common inline and display math is shown as raw source, including the delimiters and commands. The surrounding Markdown headings and prose render, but the mathematical notation does not.

Expected behavior

Please render common math delimiters in assistant messages, including:

• Inline math: \(...\) and $...$
• Display math: \[...\] and $$...$$
• Common LaTeX commands used by current models, such as fractions, sums, subscripts/superscripts, Greek letters, matrices, and aligned equations

KaTeX, MathJax, or an equivalent renderer would work. It would also be useful to preserve the original TeX when copying, keep long equations usable in narrow layouts, and fail safely for malformed expressions without breaking the rest of the message. Code blocks, escaped delimiters, and ordinary dollar amounts should remain unchanged.

Why this matters

T3 Code is useful beyond code editing, including research and technical writing. Readable math is essential for understanding probability distributions, loss functions, matrix operations, and evaluation metrics. At present, I have to copy responses elsewhere to read the equations properly.

Environment

• T3 Code desktop app
• Dark mode
• Codex provider (GPT-5.6-Luna shown in the screenshot)
• Reproduced September 4, 2026

Related reports

This is being posted in the Ideas category because the repository directs feature requests there. Related tracker items include:

• #1784: LaTeX rendering support, closed as not planned
• #8430: Render LaTeX math in chat for research workflows, closed as not planned
• #4585: Inline LaTeX renders as raw source, still open

I am not trying to create a competing duplicate report. I wanted to document a current reproducible example in the repository's requested Ideas workflow and add a concrete screenshot of the impact.

+1 this is important for all technical work, including also AI research.
Additionally, most GUIs (including Codex and CC) have supported this from the very beginning.

[dkritarth]

Yea, the only reason I am using codex is because of latex support. Other I would have been using t3 code

FYI, I'm using a local fork with latex support - it's easy enough with agents. Also allowed me some additional modifications that I wanted (e.g. some needed keybindings, mermaid support)

[dkritarth]

I was in the process of creating my own fork lol, thanks, I will definitely look at your now as well. Thanks

Not sure I pushed anything yet actually - and it also has some changes that are workflow specific for me and wouldn't work for anyone else.
Wasn't saying you should use mine, just that it's easy to do

[dkritarth]

Let me know, if you push any changes any time. If something works already, I would prefer not having to do it again lol, I have enough work as it is as a student
