Getting Started

Install the NuGet package and start using GitHub Copilot models in your Semantic Kernel application.

Prerequisites

  • A GitHub Copilot subscription (Individual, Business, or Enterprise)
  • GitHub Copilot activated in at least one editor (VS Code, JetBrains, etc.)
  • .NET 8.0 or later (for KernelBuilder extensions)

Install

dotnet add package JD.SemanticKernel.Connectors.GitHubCopilot

Minimal example

using Microsoft.SemanticKernel;
using JD.SemanticKernel.Connectors.GitHubCopilot;

var kernel = Kernel.CreateBuilder()
    .UseCopilotChatCompletion()          // auto-discovers credentials
    .Build();

var result = await kernel.InvokePromptAsync("What is dependency injection?");
Console.WriteLine(result);

That is the entire setup. The connector reads your local Copilot OAuth token, exchanges it for a short-lived API token, and routes the chat completion through the Copilot API.

Choosing a model

var kernel = Kernel.CreateBuilder()
    .UseCopilotChatCompletion(CopilotModels.ClaudeSonnet4)
    .Build();

Available model constants are in CopilotModels:

Constant Model ID
Default gpt-4o
Gpt4o gpt-4o
Gpt41 gpt-4.1
ClaudeSonnet4 claude-sonnet-4
Gemini25Pro gemini-2.5-pro
O4Mini o4-mini
