Enhancement of LaTeX Parsing Logic via Whitespace Delimitation

Description:

Current LaTeX rendering in the Gemini UI is inconsistent when math blocks are concatenated with adjacent text strings.

Observed Behavior: $formula$text or text$formula$ often fails to render as a mathematical object, displaying the raw code instead.

Root Cause: The parser fails to identify LaTeX delimiters ($) unless they are separated by whitespace, leading to a failure in the LaTeX-to-UI rendering transition.

Suggested Fix: Update the model’s response formatting logic to include mandatory leading and trailing whitespace for all LaTeX blocks.

• Incorrect: ($x^2+y^2=z^2$is a circle)

• Correct: ($x^2+y^2=z^2$ is a circle)

Impact: This adjustment will significantly reduce rendering errors in STEM-related queries and improve the overall professional quality of mathematical outputs.

Hi @LeeSiHyeong, welcome!

Can you tell us which platform you’re using? Are you testing in AI Studio or a Gemini app you’ve built?

Also, what model are you using?

Thanks!

Hi Srikanta,

Thank you for your response and for looking into this matter.

To answer your questions:

• Platform: I primarily encountered this LaTeX rendering issue while using the Gemini mobile app.

• Testing Method: To verify my proposed solution, I utilized the “Gems” feature (custom Gemini instructions). I created a Gem with a specific system instruction to always include a space before and after LaTeX delimiters.

• Validation: Through this test, I confirmed that when the model outputs equations with whitespace delimitation the parsing errors are resolved, and the visual rendering is displayed correctly on the mobile interface.

I believe that refining the native parsing logic to handle these whitespace variations or instructing the model to default to this format would significantly improve the user experience for technical and mathematical content.

Looking forward to hearing your thoughts.

Best regards,

Hi @LeeSiHyeong, apologies for the delayed response!

Thanks for the update! What you did with the “Gems” to verify the fix was exactly the right way to approach this. Providing system instructions for getting results as per your requirements is the proper way to go!

Thanks again!
