Easily Swap Endpoints to non OpenAI/Microsoft sources

Describe the solution you'd like

Something that does not require going in your OpenAISettingsInfo and manually replacing internal const strings

Describe alternatives you've considered

Maybe simply exposing endpoint url in inspector

Also ideally more easily editable schema mapping

Additional context

Lots of solutions other than OpenAI/MS providing streaming chat completions etc.

You can create as many instances of OpenAIClient as you need with custom settings to fulfill this purpose.

For example:

// Vanilla OpenAI 
var openai = new OpenAIClient("apikey");

// Custom proxy
 var authToken = await LoginAsync();
var auth = new OpenAIAuthentication($"sess-{authToken}");
var settings = new OpenAISettings(domain: "api.your-custom-domain.com");
var proxyAI = new OpenAIClient(auth, settings);

// Azure OpenAI gpt3.5-turbo
var azureAuth = new OpenAIAuthentication("sk-apiKey");
var gpt35TurboSettings = new OpenAISettings(resourceName: "your.resource.name", deploymentId: "gpt-3.5-turbo", apiVersion: "api-version");
var azureGpt35Turbo = new OpenAIClient(azureAuth, gpt35TurboSettings);

// Azure OpenAI gpt-4
var azuregpt4Settings = new OpenAISettings(resourceName: "your.resource.name", deploymentId: "gpt-4", apiVersion: "api-version");
var azureGpt4 = new OpenAIClient(azureAuth, azuregpt4Settings);
