I'm testing Foundation Model on my iPad Pro (5th gen) iOS 26. Up until late this morning, I can no longer load the SystemLanguageModel.default. I'm not doing anything interesting, something as basic as this is only going to unavailable, specifically I get unavailable reason: modelNotReady.

        let model = SystemLanguageModel.default
...
        switch model.availability {
        case .available:
            print("LM available")
        case .unavailable(let reason):
            print("unavailable reason: ", String(describing: reason))
        }

I also ran the FoundationModelsTripPlanner app, same thing. It was working yesterday, I have not modified that project either.

Why is the Model not ready? How do I fix this? Yes, I tried restarting both my laptop and iPad, no luck.

It's on Apple's end. You gotta wait for them to fix it.

I have also encountered the same issue, not sure if Apple has fixed it.

With iPadOS 26 beta 3, when the system language is English, the model is quickly downloaded. When the system language is set to another Apple Intelligence supported language, the model is never downloaded, even after calling session.prewarm().
