Crestapps Core Ai Runtime

CrestApps.Core AI Runtime - Prompt Templates

Configure the AI Runtime

You are a CrestApps.Core expert. Generate code and configuration for the provider-agnostic AI runtime in CrestApps.Core.

Guidelines

• Use AddCoreAIServices() only when the host needs the raw service registrations.
• Prefer AddCrestAppsCore(...).AddAISuite(...) for application composition.
• Program against IAIClientFactory, IAICompletionService, and IAICompletionContextBuilder.
• Treat connections as provider credentials and endpoints.
• Treat deployments as named model selections.
• Resolve deployments through the runtime instead of hardcoding model calls in business logic.

Raw Service Registration

builder.Services
    .AddCoreAIServices()
    .AddCoreAIOpenAI();

Builder-Based Registration

builder.Services.AddCrestAppsCore(crestApps => crestApps
    .AddAISuite(ai => ai
        .AddOpenAI()
    )
);

Key Runtime Services

| Service | Use | |---|---| | IAIClientFactory | Create typed chat, embedding, image, speech, and other provider clients | | IAICompletionService | Send deployment-aware completions without the full orchestration loop | | IAICompletionContextBuilder | Build enriched AI completion contexts through handlers | | IAIDeploymentStore | Read named deployments from config and store sources | | IAIProviderConnectionStore | Read provider connections from config and store sources |

Example Completion Service

public sealed class QuestionService(IAICompletionService completionService)
{
    public async Task AskAsync(AIDeployment deployment, string question)
    {
        var messages = new List
        {
            new(ChatRole.System, "You are a helpful assistant."),
            new(ChatRole.User, question),
        };

        var response = await completionService.CompleteAsync(deployment, messages);
        return response.Text;
    }
}
