# Max Tokens

This refers to the maximum number of tokens (a unit of text like a word or part of a word) the model can process in a single interaction, including both input and output.

**Detailed Explanation:**

* **Tokens:** Each token is roughly equivalent to 4 characters in English. For example, "ChatGPT is great!" has 5 tokens.
* **Limitations:** If the input and output together exceed the token limit, the model either truncates the input or the output.
* **Practical Implications:** To use the model effectively, users need to condense inputs or request shorter outputs for longer conversations.

**Example:**\
For a model with a 4,096-token limit:

* Input: "Write a 2,000-word essay."
* Output: May stop midway if the token limit is reached.
