On this talk: Bring an LLM provider to the Foundation Models framework URL: https://developer.apple.com/videos/play/wwdc2026/339/
on the coding examples a very peculiar framework is shown: import MLXFoundationModels
However I am not able to find it nowhere, there is even a code section with this framework as part of an example.
Where is this framework, there are no BETA branches on the MLX framework either.
Thanks!
