It would be more accurate to say they can do math instantaneously without even thinking, at a level far beyond what humans can do. (I assume you're talking about doing arithmetic.)

  TLDR: Astra has 8.6x better odds of doing a reasoning task without CoT than the
  next best model (Fable 5.1), and can do 7.2 serial arithmetic steps in a forward
  pass vs 4.1 for the next best model (Gemini 3.8 Flash/Fable 5.1)
