Using the Azure OpenAI SDK with .NET

This article will cover how to consume the OpenAI API using the Azure's official .NET library for OpenAI.

Azure.AI.OpenAI 1.0.0-beta.12

Azure’s official .NET library for OpenAI inference that supports Completions, Chat, and Embeddings. Works with Azure OpenAI resources as well as the non-Azure OpenAI endpoint.

Azure.AI.OpenAI 1.0.0-beta.12

For this example, let's ask ChatGPT to act like a real estate agent and create a description about a property.

The first thing to do is go to the OpenAI platform website and get the key to consume the API. You can click here for that.

Once you've got the API key, you can use the C# code below for the API consumption.

using Azure.AI.OpenAI;

// Replace this with a valid api key from Open AI platform
const string nonAzureOpenAIApiKey = "<open-ai-key>";

var openAI = new OpenAIClient(nonAzureOpenAIApiKey, new OpenAIClientOptions());

var completionOptions = new ChatCompletionsOptions
{
    // Use the appropriate name of the model (example: gpt-4)
    DeploymentName = "gpt-3.5-turbo",
    Messages =
    {
        // The system message represents instructions how the assistant should behave
        new ChatRequestSystemMessage("You'll act like you're a real estate agent."),
        // This is the prompt
        new ChatRequestUserMessage(
            @"Write a description of a property with the following characteristics:
            The property is an apartment
            The sale value is $2,160,000
            It has 80m² of living area
            It has 100m² of total area
            It has 2 parking spaces
            It has 4 bedrooms"),
    },
    MaxTokens = 256,
    Temperature = 0.4f,
    FrequencyPenalty = 0,
    PresencePenalty = 0,
    NucleusSamplingFactor = 0
};

var response = await openAI.GetChatCompletionsAsync(completionOptions, CancellationToken.None);
var responseMessageContent = response.Value.Choices[0].Message.Content;

Console.WriteLine(responseMessageContent);

And the response should look like this (or something):
