VS Code AI Model Detector is a Visual Studio Code extension that provides real-time detection and classification of AI models used by GitHub Copilot and other AI-powered extensions. It identifies the active model by reading VS Code's native storage (state.vscdb) and the chat.currentLanguageModel.panel key, then parses the model identifier to determine family and provider. The extension maintains a dynamic registry of 41+ models across major providers and cross-references it to produce detailed metadata including vendor, family, capabilities, and context windows. It relies on direct integration with VS Code's SQLite storage and the Chat Participant API to achieve high-confidence detection. It supports live updates, monitoring model changes in real time, and works across VS Code Stable, Insiders, and VSCodium. The metadata model includes information such as token limits, capabilities, and model families, enabling programmatic access via a defined ModelInfo interface. The project emphasizes attribution guidance per GIT-ATT-001 and offers runtime API calls to retrieve model capabilities and details.
