At the core of this announcement is the Llama 3.1 45B model, boasting a staggering 405 billion parameters—making it arguably the largest and most capable open-source AI model to date. Parameters function as the "brain cells" of an AI, with more parameters generally translating to better understanding and more nuanced responses. To train this behemoth, Meta utilized over 15 trillion tokens—small fragments of words, phrases, punctuation, and figures—requiring an immense computational effort.
