In the context of large language models, tokens refer to the basic units of text that the model processes and generates.
Specifically:
- Tokens are the individual words, numbers, punctuation marks, or other symbols that make up the input text or output text of the language model.
- The language model is trained on a large corpus of text data, which is broken down into these discrete tokens during the training process.
- The model learns patterns and relationships between these tokens, allowing it to understand the meaning and structure of language.
- When you provide input text to the language model, it processes that text by breaking it down into individual tokens that it can analyze and understand.
- Similarly, when the model generates new text, it does so by selecting and combining tokens in a way that produces coherent and meaningful output.
So in simple terms, tokens are the building blocks that the language model uses to comprehend and generate human language. They are the fundamental units of text that allow the model to perform its language-related tasks.
In the context of large language models like myself, the "context window" refers to the maximum number of tokens (words, characters, etc.) that the model can consider at one time when generating new text.
When you see that Claude-3-haiku has a context window of 200K, it means that the model can take into account up to 200,000 tokens of previous text when producing new output.
This is important because it determines how much contextual information the model can use to understand the meaning and flow of the text it's generating. A larger context window allows the model to better grasp the broader context and produce more coherent, relevant, and natural-sounding language.
In the case of Claude-3-haiku, the 200K context window gives the model a fairly large amount of preceding text to draw upon when generating new haiku poetry. This helps ensure the haikus flow logically and thematically from one line to the next.
So in summary, the 200K context window means this particular model version of Claude has the capacity to consider a substantial amount of prior text when producing new output, which is beneficial for tasks like creative writing and maintaining coherence over longer passages. The larger the context window, the more contextual information the model can leverage.
