ExOpenAI is an Elixir SDK for interacting with the [OpenAI APIs](https://platform.openai.com/docs/api-reference/introduction)
This SDK is fully auto-generated using [metaprogramming](https://elixirschool.com/en/lessons/advanced/metaprogramming/) and should always reflect the latest state of the OpenAI API.
**Note:** Due to the nature of auto-generating something, you may encounter stuff that isn't working yet. Make sure to report if you notice anything acting up.
## Features
- Up-to-date and complete thanks to metaprogramming and code-generation
- Implements *everything* the OpenAI has to offer
- Strictly follows the official OpenAI APIs for argument/function naming
- Handling of required arguments as function parameters and optional arguments as Keyword list in true Elixir-fashion
- Auto-generated embedded function documentation
- Auto-generated @spec definitions for dialyzer, for strict parameter typing
## Installation
Add ***:ex_openai*** as a dependency in your mix.exs file.
```elixir
def deps do
[
{:ex_openai, "~> 1.0"}
]
end
```

### Editor features: Autocomplete, specs, docs
#### Autocompletion/type-hinting through LSP / ElixirSense
<img src="images/autocomplete.png" width="500" />
#### Typechecking and diagnostics through strict @spec definitions

#### Inline docs and signatures thanks to @spec and @doc

## To Do's
- Typespecs for `oneOf` input types, currently represented as `any()`
## Configuration
```elixir
import Config
config :ex_openai,
api_key: "your-api-key", # find it at https://platform.openai.com/account/api-keys
organization_key: "your-organization-key", # find it at https://platform.openai.com/account/api-keys
http_options: [recv_timeout: 30_000] # optional, passed to [HTTPoison.Request](https://hexdocs.pm/httpoison/HTTPoison.Request.html) options
```
## Usage
Make sure to checkout the docs: https://hexdocs.pm/ex_openai
```elixir
ExOpenAI.Models.list_models
{:ok,
%{
data: [
%{
"created": 1649358449,
"id": "babbage",
"object": "model",
"owned_by": "openai",
"parent": nil,
"permission": [
%{
"allow_create_engine": false,
"allow_fine_tuning": false,
"allow_logprobs": true,
"allow_sampling": true,
"allow_search_indices": false,
"allow_view": true,
"created": 1669085501,
"group": nil,
"id": "modelperm-49FUp5v084tBB49tC4z8LPH5",
"is_blocking": false,
"object": "model_permission",
"organization": "*"
}
],
"root": "babbage"
},
...
```
Required parameters are converted into function arguments, optional parameters into the opts keyword list:
```elixir
ExOpenAI.Completions.create_completion "text-davinci-003", prompt: "The sky is"
{:ok,
%{
choices: [
%{
"finish_reason": "length",
"index": 0,
"logprobs": nil,
"text": " blue\n\nThe sky is a light blue hue that may have a few white"
}
],
created: 1677929239,
id: "cmpl-6qKKllDPsQRtyJ5oHTbkQVS9w7iKM",
model: "text-davinci-003",
object: "text_completion",
usage: %{
"completion_tokens": 16,
"prompt_tokens": 3,
"total_tokens": 19
}
}}
```
### Using ChatGPT APIs
```elixir
msgs = [
%{role: "user", content: "Hello!"},
%{role: "assistant", content: "What's up?"},
%{role: "user", content: "What ist the color of the sky?"}
]
{:ok, res} =
ExOpenAI.Chat.create_chat_completion(msgs, "gpt-3.5-turbo",
logit_bias: %{
"8043" => -100
}
)
```
### Usage of endpoints that require files to upload
Load your file into memory, then pass it into the file parameter
```elixir
duck = File.read!("#{__DIR__}/testdata/duck.png")
{:ok, res} = ExOpenAI.Images.create_image_variation(duck)
IO.inspect(res.data)
```
## How to update once OpenAI changes something?
Run `mix update_openai_docs` and commit the new `docs.yaml` file
