Ios swift – APIOpenAISwift packages not getting any responses

I am using using OpenAISwift to work with chatGTP API, I am having an issue with the API that suddenly stopped working. Despite having a valid token and enough credit for API usage, I am not receiving any response from the API. I was previously using the default repo model, but it seems that many models have been shut down by OpenAI. I changed it to .chat (.chatgpt) to use GPT-3 and also tested with the GPT-3 turbo model, but I still am not getting any data. This is a crucial issue for my AI-based app, and I would be grateful for any workaround. If it helps, here is my code.

@MainActor
class AIViewModel: ObservableObject {

    private var client: OpenAISwift?
    @Published var respnse = ""
    @Published var isLoading = false
    @Published var recievedError = false
    init() { client = OpenAISwift(config: .makeDefaultOpenAI(apiKey: "sk-*******")) }

    func ask(text: String) async {
        isLoading = true
        do {
            let result = try await client?.sendCompletion(
                with: text,
                model: .chat(.chatgpt),
                maxTokens: 200
            )
            let output = result?.choices?.first?.text.trimmingCharacters(in: .newlines) ?? "no answer"
            //print(output)
            self.respnse = output
        } catch {
            print(error.localizedDescription)
            recievedError = true
        }
        isLoading = false
    }
}

    I checked the GitHub repo, and the problem is not caused by the model.

    As you can see below, chatgpt uses the gpt-3.5-turbo model (source), which has not been deprecated:

    public enum Chat: String {
        
    /// Most capable GPT-3.5 model and optimized for chat at 1/10th the cost of text-davinci-003. Will be updated with our latest model iteration.
    /// > Model Name: gpt-3.5-turbo
    case chatgpt = "gpt-3.5-turbo"
        
    /// Snapshot of gpt-3.5-turbo from March 1st 2023. Unlike gpt-3.5-turbo, this model will not receive updates, and will only be supported for a three month period ending on June 1st 2023.
    /// > Model Name: gpt-3.5-turbo-0301
    case chatgpt0301 = "gpt-3.5-turbo-0301"
}

    The problem is probably caused by switching from the Completions API to the Chat Completions API. Message retrieval is different:

    • Completions API: .text
    • Chat Completions API: .message.content

    I don’t know Swift, but pay attention to this line:

    let output = result?.choices?.first?.text.trimmingCharacters(in: .newlines) ?? "no answer"

    Your problem is probably due to using the OpenAI legacy endpoint with completion (as mentioned already by Rok Benko)

    Try this approach using the more up-to-date OpenAISwift code from
    Swift-Almanac OpenAISwift and with sendChat(...) instead.

    Working example code:

    import Foundation
import SwiftUI
import OpenAISwift


struct ContentView: View {
    @StateObject var model = AIViewModel()
    
    var body: some View {
        Text(model.respnse)
            .task {
                await model.ask(text: "say hello")
            }
    }
}

@MainActor
class AIViewModel: ObservableObject {

    private let client: OpenAISwift
    
    @Published var respnse = ""
    @Published var isLoading = false
    @Published var recievedError = false
    
    init() {
        self.client = OpenAISwift(config: .makeDefaultOpenAI(apiKey: "sk-xxxxx"))
    }
    
    func ask(text: String) async {
        let chatArr = [ChatMessage(role: .user, content: text)]
        do {
            let results = try await client.sendChat(
                with: chatArr,
                model: .gpt4,
                maxTokens: 200
            )
            print("-----> results: (results)")
            if let output = results.choices?.first,
               let txt = output.message.content {
                self.respnse = txt
                print("n-----> respnse: (respnse)")
            }
        } catch {
            print(error)
        }
    }
 
}
