# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

  /**
   * Parses a serialized trie representation of a map of reversed public suffixes into an immutable
   * map of public suffixes. The encoded trie string may be broken into multiple chunks to avoid the
   * 64k limit on string literal size. In-memory strings can be much larger (2G).

* **Harder code search and refactoring**: Searching for identifiers, method names, or documentation becomes more difficult when multiple spellings exist for the same concept
* **Inconsistent API surface**: Public APIs with mixed spelling conventions appear less professional and polished
