Provider: A chatbot provider

In ellmer: Chat with Large Language Models

A chatbot provider

Description

A Provider captures the details of one chatbot service/API. This captures how the API works, not the details of the underlying large language model. Different providers might offer the same (open source) model behind a different API.

Usage

Provider(
  name = stop("Required"),
  model = stop("Required"),
  base_url = stop("Required"),
  params = list(),
  extra_args = list(),
  extra_headers = character(0),
  credentials = function() NULL
)

Arguments

name	Name of the provider.
model	Name of the model.
base_url	The base URL for the API.
params	A list of standard parameters created by params().
extra_args	Arbitrary extra arguments to be included in the request body.
extra_headers	Arbitrary extra headers to be added to the request.
credentials	A zero-argument function that returns the credentials to use for authentication. Can either return a string, representing an API key, or a named list of headers.

Details

To add support for a new backend, you will need to subclass Provider (adding any additional fields that your provider needs) and then implement the various generics that control the behavior of each provider.

Value

An S7 Provider object.

Examples

Provider(
  name = "CoolModels",
  model = "my_model",
  base_url = "https://cool-models.com"
)
