[Bug] Markdown parsing issue: Dollar signs ($) trigger incorrect inline math rendering

Google AI Studio

Description:
There is a Markdown rendering bug in the Google AI Studio UI. When the model generates text containing multiple financial figures using the dollar sign ($), the UI’s markdown parser incorrectly interprets the text between the dollar signs as inline LaTeX/math code.

As a result, normal sentences are rendered without spaces and in an italicized math font, making the output hard to read.

Steps to Reproduce:

  1. Go to Google AI Studio.
  2. Ask the model to generate a text that includes two currency amounts using the $ symbol, separated by normal text.
    (Example prompt: “Escribe una frase sobre finanzas que diga que la empresa vale $2000B y su flujo de caja es $70B.”)
  3. Look at the rendered output in the UI.

Expected Behavior:
The $ symbols should be treated as standard currency characters unless specifically formatted as a math block, and the text between them should render as normal paragraph text with proper spacing.

Actual Behavior:
The text between the first $ and the second $ is parsed as an inline math equation. The spaces are stripped, and the font changes to an italic math format. (e.g., $suFlujodeCajaLibreenelúltimoaño$).

Environment:

  • Google AI Studio web interface.
  • Browser: Google Chrome 145.0
  • OS: MacOS Tahoe 26.3

Attachments:
(Please see the attached screenshot where the Spanish text “su Flujo de Caja Libre en el último año” is incorrectly squished into a math formula).

This bug has not been fixed yet. Can anyone from the Google team review it and fix it?

Why nobody is fixing these easy to fix bugs? @Abhijit_Pramanik @Mrinal_Ghosh @Logan_Kilpatrick

Same issue here — confirmed. The AI Studio markdown renderer treats $...$ as LaTeX math delimiters, so any text between two dollar signs gets rendered as a math formula instead of plain text.

Quick workaround until it’s fixed: ask the model to write currency amounts without the $ symbol, or use words like “USD” instead. For example, “2000B USD” instead of “$2000B”. Not ideal, but it keeps the output readable.

This is a known conflict between standard markdown math rendering (used by many markdown parsers) and plain text with currency signs. The fix would be to only trigger math mode when the content inside $...$ actually looks like a formula — or to add a toggle in settings.

Hopefully the team picks this up soon.

Still no solution implemented for a bug reported more than 1 month ago….

Is there any place where this bug is addressed, so we can keep track of its fix?
