A leak from X leaker Lyra suggests Google is testing a math-specialized DeepThink V3 build codenamed "Mathematica," with API identifier models/deepthink-mathematica-tf-raw-thoughts, a 1M-token context window, and a 65,536-token output limit, labeled "UNSTABLEEXPERIMENTAL" and "Teamfood." Its unfiltered chain-of-thought is entertainingly raw—the model reportedly cheered "HOLY MOTHER OF MATHEMATICS" while solving a polynomial Diophantine equation. Details remain unverified.
