LLMPromptGenerator

LLMPromptGenerator[f]

represents a prompt generator that uses the function f.

LLMPromptGenerator[f,inputspec]

provides the specified inputspec to f.

Details

  • LLMPromptGenerator is used to add message-dependent context to an LLM prompt.
  • Possible values for inputspec are:
  • "Input"the last user input (default)
    "Messages"the list of messages
    "LLMEvaluator"the current LLMConfiguration[…]
    "ChatObject"the whole conversation as ChatObject[…]
    {spec1,…}an association of inputs
  • The result of f has to be valid prompt. Possible values include:
  • "text"static text
    LLMPrompt["name"]a repository prompt
    StringTemplate[…]templated text
    TemplateObject[…]template for creating a prompt
    Image[…]an image
    SemanticSearchIndex[…]a semantic search index
    {prompt1,…}a list of prompts
  • Template objects are automatically converted to strings via TemplateObject[…][].
  • A prompt created with TemplateObject can contain text and images.
  • Not every LLM supports image input.
  • If the result of f is not a string, a list of strings or an image, it will be converted using TextString.

Basic Examples  (1)

Define a prompt generator that always prepends the current evaluation date and time:

Test the generator:

Use the generator in an interaction with an LLM:

Scope  (5)

Function  (3)

Use a simple prompt:

Use a function to define the tone of the answer at evaluation time based on the input:

Try with a cowboy role:

Define a generator on a SemanticSearchIndex:

Use it to add content semantically relevant to the query:

Compare with the uninformed LLM answer:

Input Specifications  (2)

Define a generator that echoes the calling function input (default argument):

Give a custom input specification:

Possible Issues  (1)

A list of prompts does not evaluate when applied to the input:

Wrap the list using TemplateObject or Function:
