Tokens in generative AI models are the smallest units that the model processes, typically representing words, subwords, or characters. They are essential for the model to understand and generate language, breaking down text into manageable parts for processing.
Option A (Correct): "Tokens are the basic units of input and output that a generative AI model operates on, representing words, subwords, or other linguistic units": This is the correct definition of tokens in the context of generative AI models.
Option B: "Mathematical representations of words" describes embeddings, not tokens.
Option C: "Pre-trained weights of a model" refers to the parameters of a model, not tokens.
Option D: "Prompts or instructions given to a model" refers to the queries or commands provided to a model, not tokens.
