Model Discovery

The CopilotModelDiscovery class lets you enumerate all models available through your Copilot subscription at runtime.

Usage

using JD.SemanticKernel.Connectors.GitHubCopilot;

var provider = new CopilotSessionProvider(new CopilotSessionOptions());
var discovery = new CopilotModelDiscovery(provider);

var models = await discovery.DiscoverModelsAsync();

foreach (var model in models)
{
    Console.WriteLine($"{model.Id} ({model.Provider}) — {model.Name}");
}

Output example

claude-opus-4.6 (Anthropic) — Claude Opus 4.6
claude-opus-4.6-fast (Anthropic) — Claude Opus 4.6 (fast mode)
claude-sonnet-4.6 (Anthropic) — Claude Sonnet 4.6
claude-sonnet-4 (Anthropic) — Claude Sonnet 4
claude-haiku-4.5 (Anthropic) — Claude Haiku 4.5
gpt-5.3-codex (OpenAI) — GPT-5.3-Codex
gpt-5.2 (OpenAI) — GPT-5.2
gpt-5-mini (Azure OpenAI) — GPT-5 mini
gemini-3.1-pro-preview (Google) — Gemini 3.1 Pro
grok-code-fast-1 (xAI) — Grok Code Fast 1
... (41+ models total)

Interface

CopilotModelDiscovery implements IModelDiscoveryProvider from the shared abstractions:

public interface IModelDiscoveryProvider
{
    Task<IReadOnlyList<ModelInfo>> DiscoverModelsAsync(
        CancellationToken cancellationToken = default);
}

ModelInfo record

public sealed record ModelInfo(string Id, string Name, string Provider);

CLI model listing

The jdcplt tool includes model listing:

jdcplt --list-models
