Unofficial community-maintained wrapper for OpenAI REST APIs See https://platform.openai.com/docs/api-reference/introduction for further info on REST endpoints

Installation

Add :openai as a dependency in your mix.exs file.

def deps do
  [
    {:openai, "~> 0.5.2"}
  ]
end

Configuration

You can configure openai in your mix config.exs (default $project_root/config/config.exs). If you're using Phoenix add the configuration in your config/dev.exs|test.exs|prod.exs files. An example config is:

import Config

config :openai,
  # find it at https://platform.openai.com/account/api-keys
  api_key: "your-api-key",
  # find it at https://platform.openai.com/account/org-settings under "Organization ID"
  organization_key: "your-organization-key",
  # optional, passed to [HTTPoison.Request](https://hexdocs.pm/httpoison/HTTPoison.Request.html) options
  http_options: [recv_timeout: 30_000],
  # optional, useful if you want to do local integration tests using Bypass or similar
  # (https://github.com/PSPDFKit-labs/bypass), do not use it for production code,
  # but only in your test config!
  api_url: "http://localhost/"

Note: you can load your os ENV variables in the configuration file, if you set an env variable for API key named OPENAI_API_KEY you can get it in the code by doing System.get_env("OPENAI_API_KEY").

Configuration override

Client library configuration can be overwritten in runtime by passing a %OpenAI.Config{} struct as last argument of the function you need to use. For instance if you need to use a different api_key, organization_key or http_options you can simply do:

config_override = %OpenAI.Config{ api_key: "test-api-key" } # this will return a config struct with "test-api-key" as api_key, all the other config are defaulted by the client by using values taken from config.exs, so you don't need to set the defaults manually

# chat_completion with overriden config
OpenAI.chat_completion([
  model: "gpt-3.5-turbo",
  messages: [
        %{role: "system", content: "You are a helpful assistant."},
        %{role: "user", content: "Who won the world series in 2020?"},
        %{role: "assistant", content: "The Los Angeles Dodgers won the World Series in 2020."},
        %{role: "user", content: "Where was it played?"}
    ]
  ],
  config_override # <--- pass the overriden configuration as last argument of the function
)


# chat_completion with standard config
OpenAI.chat_completion(
  model: "gpt-3.5-turbo",
  messages: [
      %{role: "system", content: "You are a helpful assistant."},
      %{role: "user", content: "Who won the world series in 2020?"},
      %{role: "assistant", content: "The Los Angeles Dodgers won the World Series in 2020."},
      %{role: "user", content: "Where was it played?"}
  ]
)

you can perform a config override in all the functions, note that params argument must be passed explicitly as a list in square brackets if the configuration is to be overwritten, as in the example above.

images_generations(params)

This generates an image based on the given prompt. Image functions require some times to execute, and API may return a timeout error, if needed you can pass an optional configuration struct with HTTPoison http_options as second argument of the function to increase the timeout.

Example request

OpenAI.images_generations(
    [prompt: "A developer writing a test", size: "256x256"],

 }}

Note: this api signature has changed in v0.3.0 to be compliant with the conventions of other APIs, the alias OpenAI.image_generations(params, request_options) is still available for retrocompatibility. If you are using it consider to switch to OpenAI.images_generations(params, request_options) ASAP.

Note2: the official way of passing http_options changed in v0.5.0 to be compliant with the conventions of other APIs, the alias OpenAI.images_generations(file_path, params, request_options), but is still available for retrocompatibility. If you are using it consider to switch to OpenAI.images_variations(params, config)
