Cisharpai

Core abstractions and shared logic for the Cisharpai unified LLM client library.

What is Cisharpai?

Cisharpai provides a common interface for interacting with multiple LLM providers (OpenAI, Azure OpenAI, Azure AI Inference, Anthropic, Cohere). Your application code depends only on this core package — provider-specific logic lives in separate packages.

Key Interfaces

  • IChatCompletionClient — unified chat completion across all providers
  • IEmbeddingClient — unified text embedding across all providers

Feature Collection Pattern

Optional capabilities are discovered at runtime via IHasFeatures.Features.Get<T>():

Feature Description
IJsonOutputFeature JSON Mode and Structured Outputs
IToolCallingFeature Function/tool calling
IStreamingChatFeature Token-by-token streaming
IGroundedChatFeature RAG with document citations
IImageEmbeddingFeature Image embeddings
IMultimodalEmbeddingFeature Mixed text + image embeddings

Quick Start

using Cisharpai;
using Cisharpai.Models;

// Use any provider package to get an IChatCompletionClient
var request = new ChatCompletionRequest(
    Messages: [new LlmMessage(LlmRole.User, "Hello!")],
    Model: "gpt-4.1-nano");

var response = await client.GetChatCompletionAsync(request);
Console.WriteLine(response.Content);

Design Principles

  • No exceptions for API errors — responses use IsSuccess/ErrorMessage
  • Debuggability — access RawRequestJson/RawResponseJson on any response
  • Immutability — all DTOs are immutable record types
  • Escape hatch — ExtraParameters deep-merges arbitrary JSON into requests
