This is a community-maintained library to access OpenAI HTTP API's. The full API docs can be found here: https://beta.openai.com/docs
You can use Swift Package Manager to integrate the library by adding the following dependency in the Package.swift file or by adding it directly within Xcode.
.package(url: "https://github.com/adamrushy/OpenAISwift.git", from: "1.2.0")
CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate OpenAISwift into your Xcode project using CocoaPods, specify it in your Podfile:
pod 'OpenAISwift'Copy the source files into your own project.
Import the framework in your project:
import OpenAISwift
Create an OpenAI API key and add it to your configuration:
let openAI = OpenAISwift(authToken: "TOKEN")
This framework supports Swift concurrency; each example below has both an async/await and completion handler variant.
Predict completions for input text.
openAI.sendCompletion(with: "Hello how are you") { result in // Result<OpenAI, OpenAIError>
switch result {
case .success(let success):
print(success.choices.first?.text ?? "")
case .failure(let failure):
print(failure.localizedDescription)
}
}This returns an OpenAI object containing the completions.
Other API parameters are also supported:
do {
let result = try await openAI.sendCompletion(
with: "What's your favorite color?",
model: .gpt3(.davinci), // optional `OpenAIModelType`
maxTokens: 16, // optional `Int?`
temperature: 1 // optional `Double?`
)
// use result
} catch {
// ...
}For a full list of supported models, see OpenAIModelType.swift. For more information on the models see the OpenAI API Documentation.
Get responses to chat conversations through ChatGPT (aka GPT-3.5) and GPT-4 (in beta).
do {
let chat: [ChatMessage] = [
ChatMessage(role: .system, content: "You are a helpful assistant."),
ChatMessage(role: .user, content: "Who won the world series in 2020?"),
ChatMessage(role: .assistant, content: "The Los Angeles Dodgers won the World Series in 2020."),
ChatMessage(role: .user, content: "Where was it played?")
]
let result = try await openAI.sendChat(with: chat)
// use result
} catch {
// ...
}All API parameters are supported, except streaming message content before it is completed:
do {
let chat: [ChatMessage] = [...]
let result = try await openAI.sendChat(
with: chat,
model: .chat(.chatgpt), // optional `OpenAIModelType`
user: nil, // optional `String?`
temperature: 1, // optional `Double?`
topProbabilityMass: 1, // optional `Double?`
choices: 1, // optional `Int?`
stop: nil, // optional `[String]?`
maxTokens: nil, // optional `Int?`
presencePenalty: nil, // optional `Double?`
frequencyPenalty: nil, // optional `Double?`
logitBias: nil // optional `[Int: Double]?` (see inline documentation)
)
// use result
} catch {
// ...
}Generate an image based on a prompt.
openAI.sendImages(with: "A 3d render of a rocket ship", numImages: 1, size: .size1024) { result in // Result<OpenAI, OpenAIError>
switch result {
case .success(let success):
print(success.data.first?.url ?? "")
case .failure(let failure):
print(failure.localizedDescription)
}
}Edits text based on a prompt and an instruction.
do {
let result = try await openAI.sendEdits(
with: "Improve the tone of this text.",
model: .feature(.davinci), // optional `OpenAIModelType`
input: "I am resigning!"
)
// use result
} catch {
// ...
}Classifies text for moderation purposes (see OpenAI reference for more info).
do {
let result = try await openAI.sendModeration(
with: "Some harmful text...",
model: .moderation(.latest) // optional `OpenAIModelType`
)
// use result
} catch {
// ...
}Get a vector representation of a given input that can be easily consumed by machine learning models and algorithms.(see OpenAI reference for more info).
do {
let result = try await openAI.sendEmbeddings(
with: "The food was delicious and the waiter..."
)
// use result
} catch {
// ...
}I created this mainly for fun, we can add more endpoints and explore the library even further. Feel free to raise a PR to help grow the library.
