My app failed me, so I had to go back and remake the rest of my thread in another post. I don't even know why it even decided to post this one but not the rest of the thread. Made me mad lol

And there's nothing else I'd rather dooooooooo

Demo of Foundry Local SDK incorporated and running within Win UI!

It's awesome to see this slick example of sending a prompt into a local model and parsing the data from it in a particular format. RIGHT within the app. \o/.

Foundry Local!

I've been using this locally to test, experimented with a chat provider implementation in VS Code and currently have it implemented in the app I'm posting this from lol

Get started with winget install Microsoft.FoundryLocal

And play with models that run on NPU!

AI Dev Gallery!

This app was integral to me jumping into learning how to integrate local LLMs into applications. The samples are awesome

Nice! Its running the benchmark, analyzing the perf trace and it found a top insight to address.

It's fixing the issue :O.

Interesting point to remember, you have to still understand whats going on because it returned something that wasn't the best fix the first time.

It's interesting of the success with GPT 4.1, because I've always had the bad luck with it. It's always decided to delete my code or paste it in a weird format that ultimatley breaks it lol.
