And now it's available via `pip install apple-fm-sdk`

Today we are introducing a Python SDK for Mac's on-device LLM! github.com/apple/python-a… apple.github.io/python-apple-f…

@mattt Nice work!!

Introducing AnyLanguageModel: A Swift package that provides a drop-in replacement for Apple's Foundation Models framework with support for custom language model providers. github.com/mattt/AnyLangu… Just change your import statement:

A list of apps that are using Apple's local models to introduce new features. techcrunch.com/2025/09/19/how…

Trying out lots of new apps from App Store today! Love all these delightful features leveraging our on-device LLM 🤩 #iOS26

Prime example for how to apply Foundation Models in your app

My @DarkNoiseApp update with the new iOS 26 Liquid Glass design, and a new Magic Mix feature (demoed here) powered by the new Foundation Model API & Apple Intelligence is ready for tomorrow's release! If you're press writing about app updates, my press release is below 🧵👇

9/11だけではありますが、Foundation Model フレームワークのエンジニアも参加してくれることになりました。もし直接エンジニアと話したいって方は9/11にぜひご応募ください。また、9/9,10の枠も、もちろんお待ちしております。

The team that built the Foundation Models framework is hiring! Join us to create the best LLM APIs, both for app developers and for Apple teams. jobs.apple.com/en-us/details/…

@rudrank That’s right — guardrails will no longer be triggered by sensitive/controversial topics that are not fundamentally unsafe. If you ask the model to summarize or rewrite such content, the model will do as told; otherwise, the model may still refuse with an explanation.

Has anyone tried this? I am not able to trigger guardrails. Any prompt to experiment with default and permissiveContentTransformations I tried with summarizing and rewriting a few political ones but it works on both

If you missed the WWDC25 recap broadcast, video is now on Youtube! I cover: - On-device LLM using the Foundation Models framework - Custom models using CoreML - Latest research models using open-source MLX and more! Enjoy! youtube.com/watch?v=9lO3ds…

@JPEGuin You need to recompile your app using Xcode 26 beta 5 to run the app on OS 26 beta 5. We made some final API improvements and removed APIs that were deprecated in previous betas.

Can anyone help me out here? My app's crashing on launch for many of my users, seems to be related to Foundation Models based on the backtrace.

iOS 26 Beta 5 dropped today and contains some exciting additions to the Foundation Models framework. (1/6)

New Blog Post: Using the FoundationModels Framework for Streaming from external LLM providers Link below in comments...

There is a new refusal case with explanation. They explicitly mention that a token is 3-4 characters in English. I had asked for a property to keep count of it in a feedback but the response was that it is not on the engineering team's roadmap

Biggest change in foundation model framework! There is a new permissiveContentTransformations guardrail!

@rudrank @NatashaTheRobot @emcro @SwiftyAlex @_julianschiavo +1. An example (prompt + code) that reproduces the issue is the best kind of actionable feedback. We'd like to look into this!

@NatashaTheRobot @emcro @SwiftyAlex @_julianschiavo You have to provide an example as well

Is anyone else having a horrible time with using Tools in the new FoundationModels framework update in Beta 4? The model will not call the tool and will instead insert [Tool X was called] and hallucinate an answer. And that's not when it's failing on calling the tool entirely b/c it can't generate an argument...
