What is OpenAI

OpenAI is a non-profit artificial intelligence research organization founded in San Francisco, California in 2015. It was created with the purpose of advancing digital intelligence in ways that benefit humanity as a whole and promote societal progress. The organization strives to develop AI (Artificial Intelligence) programs and systems that can think, act and adapt quickly on their own – autonomously. OpenAI's mission is to ensure safe and responsible use of AI for civic good, economic growth and other public benefits; this includes cutting-edge research into important topics such as general AI safety, natural language processing, applied reinforcement learning methods, machine vision algorithms etc.

The OpenAI API can be applied to virtually any task that involves understanding or generating natural language or code. We offer a spectrum of models with different levels of power suitable for different tasks, as well as the ability to fine-tune your own custom models. These models can be used for everything from content generation to semantic search and classification.

Installation

OpenAI is available with Swift Package Manager. The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. Once you have your Swift package set up, adding OpenAI as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/MacPaw/OpenAI.git", branch: "main")
]

Usage

Initialization

To initialize API instance you need to obtain API token from your Open AI organization.

Remember that your API key is a secret! Do not share it with others or expose it in any client-side code (browsers, apps). Production requests must be routed through your own backend server where your API key can be securely loaded from an environment variable or key management service.

Once you have a token, you can initialize OpenAI class, which is an entry point to the API.

⚠️ OpenAI strongly recommends developers of client-side applications proxy requests through a separate backend service to keep their API key safe. API keys can access and manipulate customer billing, usage, and organizational data, so it's a significant risk to expose them.

let openAI = OpenAI(apiToken: "YOUR_TOKEN_HERE")

Optionally you can initialize OpenAI with token, organization identifier and timeoutInterval.

let configuration = OpenAI.Configuration(token: "YOUR_TOKEN_HERE", organizationIdentifier: "YOUR_ORGANIZATION_ID_HERE", timeoutInterval: 60.0)
let openAI = OpenAI(configuration: configuration)

Once token you posses the token, and the instance is initialized you are ready to make requests.

Completions

Given a prompt, the model will return one or more predicted completions, and can also return the probabilities of alternative tokens at each position.

Request

struct CompletionsQuery: Codable {
    /// ID of the model to use.
    public let model: Model
    /// The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays.
    public let prompt: String
    /// What sampling temperature to use. Higher values means the model will take more risks. Try 0.9 for more creative applications, and 0 (argmax sampling) for ones with a well-defined answer.
    public let temperature: Double?
    /// The maximum number of tokens to generate in the completion.
    public let maxTokens: Int?
    /// An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
    public let topP: Double?
    /// Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
    public let frequencyPenalty: Double?

Images

Given a prompt and/or an input image, the model will generate a new image.

As Artificial Intelligence continues to develop, so too does the intriguing concept of Dall-E. Developed by OpenAI, a research lab for artificial intelligence purposes, Dall-E has been classified as an AI system that can generate images based on descriptions provided by humans. With its potential applications spanning from animation and illustration to design and engineering - not to mention the endless possibilities in between - it's easy to see why there is such excitement over this new technology.

    public let n: Int?
    /// The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024.

GPT-4 models are supported.

For example to use basic GPT-4 8K model pass .gpt4 as a parameter.

let query = ChatQuery(model: .gpt4, messages: [
    .init(role: .system, content: "You are Librarian-GPT. You know everything about the books."),
    .init(role: .user, content: "Who wrote Harry Potter?")
])
let result = try await openAI.chats(query: query)
XCTAssertFalse(result.choices.isEmpty)

You can also pass a custom string if you need to use some model, that is not represented above.

List Models

Lists the currently available models.

Response

public struct ModelsResult: Codable, Equatable {
    
    public let data: [ModelResult]
    public let object: String
}

Example

openAI.models() { result in
  //Handle result here
}
//or
let result = try await openAI.models()

Retrieve Model

Retrieves a model instance, providing ownership information.

Request

public struct ModelQuery: Codable, Equatable {
    
    public let model: Model
}

Response

public struct ModelResult: Codable, Equatable {

    public let id: Model
    public let object: String
    public let ownedBy: String
}

Example

let query = ModelQuery(model: .gpt4)
openAI.model(query: query) { result in
  //Handle result here
}
//or
let result = try await openAI.model(query: query)

Review Models Documentation for more info.

Moderations

Given a input text, outputs if the model classifies it as violating OpenAI's content policy.

Request

public struct ModerationsQuery: Codable {
    
    public let input: String
    public let model: Model?
}

Response

public struct ModerationsResult: Codable, Equatable {

    public let id: String
    public let model: Model
    public let results: [CategoryResult]
}

Example

let query = ModerationsQuery(input: "I want to kill them.")
openAI.moderations(query: query) { result in
  //Handle result here
}
//or
let result = try await openAI.moderations(query: query)

Utilities

The component comes with several handy utility functions to work with the vectors.

public struct Vector {

    /// Returns the similarity between two vectors
    ///
    /// - Parameters:
    ///     - a: The first vector
    ///     - b: The second vector
    public static func cosineSimilarity(a: [Double], b: [Double]) -> Double {
        return dot(a, b) / (mag(a) * mag(b))
    }

    /// Returns the difference between two vectors. Cosine distance is defined as `1 - cosineSimilarity(a, b)`
    ///
    /// - Parameters:
    ///     - a: The first vector
    ///     - b: The second vector
    public func cosineDifference(a: [Double], b: [Double]) -> Double {
        return 1 - Self.cosineSimilarity(a: a, b: b)
    }
}

Example

let vector1 = [0.213123, 0.3214124, 0.421412, 0.3214521251, 0.412412, 0.3214124, 0.1414124, 0.3214521251, 0.213123, 0.3214124, 0.1414124, 0.4214214, 0.213123, 0.3214124, 0.1414124, 0.3214521251, 0.213123, 0.3214124, 0.1414124, 0.3214521251]
let vector2 = [0.213123, 0.3214124, 0.1414124, 0.3214521251, 0.213123, 0.3214124, 0.1414124, 0.3214521251, 0.213123, 0.511515, 0.1414124, 0.3214521251, 0.213123, 0.3214124, 0.1414124, 0.3214521251, 0.213123, 0.3214124, 0.1414124, 0.3213213]
let similarity = Vector.cosineSimilarity(a: vector1, b: vector2)
print(similarity) //0.9510201910206734

In data analysis, cosine similarity is a measure of similarity between two sequences of numbers.

Contribution Guidelines

Make your Pull Requests clear and obvious to anyone viewing them.
Set main as your target branch.

Use Conventional Commits principles in naming PRs and branches:

Feat: ... for new features and new functionality implementations.
Bug: ... for bug fixes.
Fix: ... for minor issues fixing, like typos or inaccuracies in code.
Chore: ... for boring stuff like code polishing, refactoring, deprecation fixing etc.

PR naming example: Feat: Add Threads API handling or Bug: Fix message result duplication

Branch naming example: feat/add-threads-API-handling or bug/fix-message-result-duplication

Write description to pull requests in following format:
