Breaking Changes: I am going to update library namespace from Betalgo.OpenAI.GPT3 to OpenAI.GPT3. This is the first time I am trying to update my nuget packageId. If something broken, please be patient. I will be fixing it soon. Reverted namespace change, maybe next time.

Small Typo change on model name Model.GPT4 to Model.GPT_4

ServiceCollection.AddOpenAIService(); now returns IHttpClientBuilder which means it allows you to play with httpclient object. Thanks for all the reporters and @LGinC. Here is a little sample

ServiceCollection.AddOpenAIService()
.ConfigurePrimaryHttpMessageHandler((s => new HttpClientHandler
{
    Proxy = new WebProxy("1.1.1.1:1010"),
});
