I am excited to try Foundation Models during WWDC, but it doesn't work at all for me. When running on my iPad Pro M4 with iPadOS 26 seed 1, I get the following error even when running the simplest query:

let prompt = "How are you?"                            
let stream = session.streamResponse(to: prompt)
for try await partial in stream {
    self.answer = partial
    self.resultString = partial
}

In the Xcode console, I see the following error:

assetsUnavailable(FoundationModels.LanguageModelSession.GenerationError.Context(debugDescription: "Model is unavailable", underlyingErrors: []))

I have verified that Apple Intelligence is enabled on my iPad. Any tips on how can I get it working? I have also submitted this feedback: FB17896752

Did you check the model availability before using it, as shown in the Apple sample code? That can probably give you a better idea about why the model is unavailable.

One typical reason is that Apple Intelligence isn't enabled on the device, which you have ruled out. The other thing I am wondering is if the issue is related to the supported languages and regions. Did you try to set your system language to English and region to United States?

I am getting similar error, MODEL NOT AVAILABLE. I am running XCODE BETA Version 26.0 beta (17A5241e) Mac Sequoia 15.5 on high performance Mac Pro

Trying running sample code from Video

import FoundationModels import Playgrounds

#Playground { if #available(iOS 26.0, *) { let session = LanguageModelSession() } else { // Fallback on earlier versions } let response = try await session.respond(to: "Whats a good name for a trip to Japan? Reply only with a title") }

Cannot find 'session' in scope.

DOES THIS WORK on SIMULATORS with the Beta or is there something I am missing?

I experienced the same issue, but I set my region to United States, the device language to English, and Siri’s language to English, and after waiting a while, it was resolved!
