SemanticKernelPooling 1.5.3

SemanticKernelPooling

SemanticKernelPooling is a .NET library designed to facilitate seamless integration with multiple AI service providers, such as OpenAI, Azure OpenAI, HuggingFace, Google, Mistral AI, and others. It utilizes a kernel pooling approach to manage resources efficiently and provide robust AI capabilities in your .NET applications.

Features

• Kernel Pooling: Efficiently manage and reuse kernels for different AI service providers.
• Support for Multiple Providers: Integrates with various AI providers like OpenAI, Azure OpenAI, HuggingFace, Google, Mistral AI, and more.
• Extensibility: Easily extendable to support additional AI service providers.
• Customizable Configuration: Allows fine-tuning of kernel behavior and AI service integration settings.
• Logging Support: Integrated with Microsoft.Extensions.Logging for detailed logging and diagnostics.
• Error Handling and Retry Logic: Implements robust error handling using Polly for retry policies, especially useful for managing API quotas and transient errors.

Getting Started

Prerequisites

• .NET 8.0 or higher
• NuGet packages:
  • Microsoft.Extensions.DependencyInjection
  • Microsoft.Extensions.Logging
  • Microsoft.SemanticKernel
  • Polly for advanced retry logic

Installation

To install SemanticKernelPooling, you can use the NuGet package manager:

dotnet add package SemanticKernelPooling

Basic Usage

1. Configure Services

   Start by configuring the services in your Program.cs or Startup.cs file:

   using Microsoft.Extensions.DependencyInjection;
   using Microsoft.Extensions.Logging;
   using SemanticKernelPooling;
   using SemanticKernelPooling.Connectors.OpenAI;
   
   var services = new ServiceCollection();
   services.AddLogging(configure => configure.AddConsole());
   services.UseSemanticKernelPooling(); // Core service pooling registration
   services.UseOpenAIKernelPool(); // Register OpenAI kernel pool
   services.UseAzureOpenAIKernelPool(); // Register Azure OpenAI kernel pool
   
   var serviceProvider = services.BuildServiceProvider();
   

2. Configure Providers

   You need to set up configuration settings for each AI service provider you intend to use. These settings can be defined in a appsettings.json or any configuration source supported by .NET:

   {
    "AIServiceProviderConfigurations": [
    {
    "UniqueName": "OpenAI",
    "ServiceType": "OpenAI",
    "ApiKey": "YOUR_OPENAI_API_KEY",
    "ModelId": "YOUR_MODEL_ID"
    },
    {
    "UniqueName": "AzureOpenAI",
    "ServiceType": "AzureOpenAI",
    "DeploymentName": "YOUR_DEPLOYMENT_NAME",
    "ApiKey": "YOUR_AZURE_API_KEY",
    "Endpoint": "YOUR_ENDPOINT",
    "ModelId": "YOUR_MODEL_ID",
    "ServiceId": "YOUR_SERVICE_ID"
    }
    // Add more providers as needed
    ]
   }
   

3. Retrieve a Kernel and Execute Commands

   Once the service providers are configured and registered, you can retrieve a kernel from the pool and execute commands:

   var kernelPoolManager = serviceProvider.GetRequiredService<IKernelPoolManager>();
   
   // Example: Getting a kernel for OpenAI
   using var kernelWrapper = await kernelPoolManager.GetKernelAsync(AIServiceProviderType.OpenAI);
   
   // Use the kernel to perform AI operations
   var response = await kernelWrapper.Kernel.ExecuteAsync("What is Semantic Kernel?");
   Console.WriteLine(response);
   
   // Return the kernel to the pool after use
   

Advanced Usage

4. Using Retry Policies

   To handle API rate limits and transient errors, use Polly to define retry policies:

   AsyncPolicy httpTimeoutAndRetryPolicy = Policy
    .Handle<Exception>(ex => ex.IsTransientError())
    .WaitAndRetryAsync(
    retryCount: 6,
    sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)) + TimeSpan.FromMilliseconds(new Random().Next(0, 3000)),
    onRetry: (exception, timespan, retryCount, context) =>
    {
    logger.LogError($"Retry {retryCount} after {timespan.TotalSeconds} seconds due to: {exception.Message}");
    });
   

5. Adding New AI Providers

   To add support for a new AI provider, follow these steps:

   • Create a Configuration Class: Define a new configuration class inheriting from AIServiceProviderConfiguration.

   • Implement a Kernel Pool Class: Create a new kernel pool class inheriting from AIServicePool<T>.

   • Register the New Provider: Add the registration method in the ServiceExtension class to register your new provider with the DI container.

   For example, to add a new "CustomAI" provider:

   public record CustomAIConfiguration : AIServiceProviderConfiguration
   {
    public required string ModelId { get; init; }
    public required string ApiKey { get; init; }
    // Additional settings...
   }
   
   class CustomAIKernelPool(
    CustomAIConfiguration config,
    ILoggerFactory loggerFactory)
    : AIServicePool<CustomAIConfiguration>(config)
   {
    protected override void RegisterChatCompletionService(IKernelBuilder kernelBuilder, CustomAIConfiguration config, HttpClient? httpClient)
    {
    // Register service logic...
    }
   
    protected override ILogger Logger { get; } = loggerFactory.CreateLogger<CustomAIKernelPool>();
   }
   
   public static class ServiceExtension
   {
    public static void UseCustomAIKernelPool(this IServiceProvider serviceProvider)
    {
    var registrar = serviceProvider.GetRequiredService<IKernelPoolFactoryRegistrar>();
    registrar.RegisterKernelPoolFactory(
    AIServiceProviderType.CustomAI,
    (aiServiceProviderConfiguration, loggerFactory) =>
    new CustomAIKernelPool((CustomAIConfiguration)aiServiceProviderConfiguration, loggerFactory));
    }
   }
   

Supported Providers

• OpenAI: Use OpenAIConfiguration and OpenAIKernelPool to interact with OpenAI services.
• Azure OpenAI: Use AzureOpenAIConfiguration and AzureOpenAIKernelPool for Azure OpenAI.
• HuggingFace: Use HuggingFaceConfiguration and HuggingFaceKernelPool to integrate with HuggingFace models.
• Google AI: Use GoogleConfiguration and GoogleKernelPool for Google AI services.
• Mistral AI: Use MistralAIConfiguration and MistralAIKernelPool to leverage Mistral AI services.
• Custom Providers: Easily extend to support other providers by following the extensibility guidelines.
