Dependency Injection

Add to service collection the OpenAi service in your DI

var apiKey = configuration["Azure:ApiKey"];
services.AddOpenAi(settings =>
{
    settings.ApiKey = apiKey;
});

Add to service collection the OpenAi service in your DI with Azure integration

When you want to use the integration with Azure, you need to specify all the models you're going to use. In the example you may find the model name for DavinciText3. You still may add a custom model, with AddDeploymentCustomModel.

builder.Services.AddOpenAi(settings =>
{
    settings.ApiKey = apiKey;
    settings.Azure.ResourceName = "AzureResourceName (Name of your deployed service on Azure)";
    settings.Azure
        .AddDeploymentTextModel("Test (The name from column 'Model deployment name' in Model deployments blade in your Azure service)", TextModelType.DavinciText3);
});

Models

List and describe the various models available in the API. You can refer to the Models documentation to understand what models are available and the differences between them. You may find more details here, and here samples from unit test.

List Models

Lists the currently available models, and provides basic information about each one such as the owner and availability.

IOpenAiApi _openAiApi;
var results = await _openAiApi.Model.ListAsync();

Retrieve Models

Retrieves a model instance, providing basic information about the model such as the owner and permissioning.

IOpenAiApi _openAiApi;
var result = await _openAiApi.Model.RetrieveAsync(TextModelType.DavinciText3.ToModelId());

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. You may find more details here, and here samples from unit test

IOpenAiApi _openAiApi;
var results = await _openAiApi.Completion
    .Request("One Two Three Four Five Six Seven Eight Nine One Two Three Four Five Six Seven Eight")
    .WithModel(TextModelType.CurieText)
    .WithTemperature(0.1)
    .SetMaxTokens(5)
    .ExecuteAsync();

Streaming

IOpenAiApi _openAiApi;
var results = new List<CompletionResult>();
        await foreach (var x in _openAiApi.Completion
           .Request("Today is Monday, tomorrow is", "10 11 12 13 14")
           .WithTemperature(0)
           .SetMaxTokens(3)
           .ExecuteAsStreamAsync())
        {
            results.Add(x);
        }

Chat

Given a chat conversation, the model will return a chat completion response. You may find more details here, and here samples from unit test.

IOpenAiApi _openAiApi;
var results = await _openAiApi.Chat
        .Request(new ChatMessage { Role = ChatRole.User, Content = "Hello!! How are you?" })

        .WithModel(ChatModelType.Gpt35Turbo)
        .WithTemperature(1)
        .ExecuteAsStreamAsync())
        {
            results.Add(x);
        }

Edits

Given a prompt and an instruction, the model will return an edited version of the prompt. You may find more details here, and here samples from unit test.

IOpenAiApi _openAiApi;
var results = await _openAiApi.Edit
        .Request("Fix the spelling mistakes")
        .WithModel(EditModelType.TextDavinciEdit)
