Ask HN: What prompt do you use to get Claude to consistently render LaTeX?

TobyTheCamel Tuesday, March 03, 2026

I currently have subscriptions to both Claude and ChatGPT. I generally prefer the former but find I can't fully commit to it for my maths-heavy workload as it often struggles to correctly render LaTeX.

An example of this failed rendering is here [1]. If I use Claude for all of my work, I come across issues like this or worse at least once a day. Instead, I find it easier just to ask any maths questions to ChatGPT which seems to have a much more robust system for outputting LaTeX.

I would love to merge my subscriptions though, so I'm here to ask whether anyone has a system prompt that has been effective in guiding Claude towards producing valid LaTeX. I've tried a few prompts myself but struggled to find anything that it consistently followed.
