Is Core AI capable of submitting Neural Engine requests in the background?

In iOS 26, Core ML reliably submits inference requests targeting the Neural Engine in the background. In iOS 27 Seed 1, this capability is currently broken.

Is Core AI expected to reliably submit inference requests targeting the Neural Engine in the background?

With Core AI, I believe you can express a preference for NeuralEngine but it's up to Core AI.

The question was primarily about background capability.
