When an AI model wrote a formula between \[ and \] or \( and \), the web chat showed the raw notation, brackets and backslashes included, instead of the formula. The chat, Canvas, shared chats, the in-app assistant and the try-it chat on ToRun's home page now draw formulas written between \[ and \], $$ and $$, or \( and \) as math. A single dollar sign, as in a price, stays text, and so does code. The mobile app already draws them.
