Frustrated trying to get the extension to work, but only getting cryptic errors.

[jessehouwing]

Expected Behavior

The model either works, or provides a clear error message on why it can't
Ideally it filters the models dropdown by the models that my system is capable running, instead of having me figure it out.

Actual Behavior

Cryptic error messages and failed chats

Steps to Reproduce the Problem

1. installed Foundry local in vscode
2. installed CUDA 13.3.0
3. restarted visual studio code
4. All optimized models throw cryptic error mesages

Specifications

• extension version: 1.4.2
• Version: vscode 1.123.0
• Platform: Windows x64

I tried -npu, -cuda, -gpu -openvino models. Only the -gpu seems to try to work, but takes FOREVER even for small requets
