At each generation step, the model outputs raw values (logits) for every token in the vocabulary. Passing these through a softmax function yields a probability distribution. Selecting the absolute highest probability token every time results in repetitive, looping text. Instead, inference systems employ advanced selection heuristics:

: Allowing the model to focus on different parts of the input sequence simultaneously. Gather high-quality open datasets like The Pile or

: Guides you through every stage, including tokenization , attention mechanisms, and model training.

Ideal for translation or summarization where you map an input sequence to a distinct output sequence.
