"# Prompt Serialization\n",
|
|
"\n",
|
|
"It is often preferrable to store prompts not as python code but as files. This can make it easy to share, store, and version prompts. This notebook covers how to do that in LangChain, walking through all the different types of prompts and the different serialization options.\n",
|
|
"\n",
|
|
"At a high level, the following design principles are applied to serialization:\n",
|
|
"\n",
|
|
"1. Both JSON and YAML are supported. We want to support serialization methods that are human readable on disk, and YAML and JSON are two of the most popular methods for that. Note that this rule applies to prompts. For other assets, like Examples, different serialization methods may be supported.\n",
|
|
"\n",
|
|
"2. We support specifying everything in one file, or storing different components (templates, examples, etc) in different files and referencing them. For some cases, storing everything in file makes the most sense, but for others it is preferrable to split up some of the assets (long templates, large examples, reusable components). LangChain supports both.\n",
|
|
"\n",
|
|
"There is also a single entry point to load prompts from disk, making it easy to load any type of prompt."
