Who this page is for

This page is for Windows users building a local stack one layer at a time: a model runtime, a chat interface, an optional coding assistant, and retrieval only when it solves a real document task. Keep the first setup small enough to troubleshoot. Confirm each local API works on its own before connecting containers, editor extensions, or additional machines.

Selection criteria

  • A runtime with a documented Windows installation and support for the target model and hardware.
  • One local API endpoint that the selected chat or coding client can actually reach.
  • Clear model, log, and workspace storage locations for backup and privacy review.
  • A simple upgrade path that does not require replacing every layer at the same time.
  • Repeatable checks for model loading, response latency, document retrieval, and failure recovery.

FAQ

What should I install first for local AI on Windows?

Install one runtime and load one model before adding a separate interface. Use its native chat or API test to confirm the model works, then connect Open WebUI, a coding assistant, or a retrieval layer one at a time.

Do I need Docker or WSL for a Windows local AI stack?

Not for every stack. Some runtimes and desktop tools install directly on Windows, while particular servers or supporting services may use containers or WSL. Choose the smallest deployment path supported by the tools you actually need.

Why can a Windows client fail to reach a local model that is already running?

The client may be using the wrong host, port, API path, or container network. Test the runtime endpoint from the same environment as the client and remember that localhost inside a container refers to that container, not automatically to the Windows host.
