what’s in the previous tokens and what the LLM has seen during its training. When you write a prompt, you are attempting to set up the LLM to predict the right sequence of tokens. Prompt engineering is task. Output length An important configuration setting is the number of tokens to generate in a response. Generating more tokens requires more computation from the LLM, leading to higher energy consumption or textually succinct in the output it creates, it just causes the LLM to stop predicting more tokens once the limit is reached. If your needs require a short output length, you’ll also possibly need

Note: In AI language models, tokens represent basic units of text (e.g., words or sub-words) used during training. Training dataset sizes are often measured in total tokens processed.
