Local Model Integrator
Bring your own AI model into Visual Studio — local or remote — as a code-aware, read-only assistant that stays strictly inside your open solution and is honest about where your code goes.
Point it at any OpenAI-compatible endpoint (Ollama, LM Studio, vLLM, or the OpenAI API). It reads only the currently-open solution, suggests changes in chat for you to apply yourself, and never writes to your files.
What it does
- Agentic, code-aware chat. Every message can run a tool-using loop that inspects your actual code with Roslyn (find references, symbols, file outlines), content search, and file reads — so answers come from your code, not a guess.
- Works with any OpenAI-compatible model. Uses native function/tool-calling when your endpoint supports it, and falls back to a text-based tool protocol for models that don't — so even a modest local model is useful.
- Editor actions. Right-click in a code file for Explain / Refactor / Generate Tests / Add Doc Comments.
- Streaming responses with a collapsible reasoning view, prompt history (Ctrl+↑ / Ctrl+↓), and a Test Connection probe.
Your code, your boundary
This extension is deliberately conservative about your source:
- Solution-only. It can read only files in the currently-open solution. No solution open → it's disabled. Files outside the solution are refused, even if open in another tab.
- One destination, your choice. Your code is only ever sent to the API URL you configure. Nothing phones home.
- Visible egress. A chip shows where requests go and whether they're encrypted (🟢 this machine · 🟡 external + https · 🔴 external + http), and you're asked once before anything leaves your machine.
- Read-only. It proposes edits in chat; you review, copy, and apply them. It does not touch your files.
Setup
- Tools → Options → Local Model Integrator — set your API URL, Model Name, and Protocol.
- Test Connection to confirm reachability and capabilities.
- Open the chat (View → Other Windows → Local Model Integrator), open a solution, and start asking.
Requirements
- Visual Studio 2026 (18.x or later).
- An OpenAI-compatible chat-completions endpoint — local (Ollama, LM Studio, vLLM, …) or remote.
