Resource Unit conversions

Each component has a unique Resource Unit that allows for a certain amount of usage of the LLM, measured in tokens.

Note:

A token is a collection of characters that has a semantic meaning for a model. The token includes the following transformation capabilities:

Tokenization converts the words or an output in a prompt into tokens.
Prompt text is converted to tokens before they are processed by one or more foundation models.
The raw output from a model is represented by tokens, where the output is converted to words and displayed in the prompt editor.
Each line of code has a different number of tokens. However, the estimation is that transforming a line of COBOL code represents approximately 30 tokens.
