3. [PowerToys settings > Advanced Paste > Paste with AI (On) > Add model > Foundry Local](https://learn.microsoft.com/en-us/windows/powertoys/advanced-paste#adding-a-model-provider)

### ✔️ Expected Behavior

phi-4-mini model available to select.
Paste with AI works with that model activated.

### ❌ Actual Behavior

Foundry Local provider configuration window says No models downloaded. Run Foundry Local to download or add a local model.

I have tried:
* the refresh button.
* `foundry server restart`.
* restarting PowerToys.
* installing & loading another model (qwen3.5-2b-text).

Start in the Advanced Paste settings flow at Paste with AI > Add model > Foundry Local, then inspect how it discovers models from the Foundry Local service. Reproduce with the listed Foundry Local commands and verify the loaded phi-4-mini model is shown and can be selected for Paste with AI.
