Use the OpenAI Decisions API

Makes a decider for a model of the OpenAI Decisions API (https://api.openai.com).

Usage

decider_openai(model = NULL, credentials = NULL, input = NULL)

Arguments

model

The model name. NULL (the default) uses "gpt-6-luna" and prints a message that names it.

credentials

A function with no arguments that returns the key. NULL (the default) reads the environment variable OPENAI_API_KEY each time decide() sends requests. You generally should not need this argument. Set OPENAI_API_KEY instead. The best place to set it is .Renviron. Open that file with usethis::edit_r_environ(). The usethis package is optional: you can also edit .Renviron by hand. Give a function for more control, for example to read the key from a secret store. The decider keeps the function, not the key.

input

The input type that the model reads: "text", "image" or "text+image". NULL (the default) takes it from the internal table of input types; a model that is not in the table is not checked. decide() stops before any request when an input does not fit.

Value

A decider object for decide(). It holds no key.

Details

A ChatGPT Plus membership does not give access to the API. You need to sign up for a developer account (and pay for it) at the developer platform. Then set the environment variable OPENAI_API_KEY.

OpenAI does not report a cost, so .cost is NA in the output of decide().
