Foundation Models

At WWDC 25 Apple opened up the on-device large-language model that powers Apple Intelligence to every iOS, iPadOS, macOS and visionOS app via a new “Foundation Models” framework. The model is a compact ~3 billion-parameter LLM that has been quantized to just 2 bits per weight, so it runs fast, offline and entirely on the user’s device, keeping data private while still handling tasks such as summarization, extraction, short-form generation and structured reasoning. ([developer.apple.com][1], [machinelearning.apple.com][2]) Below is a developer-focused English-language overview—based mainly on Apple’s own announcements, docs and WWDC sessions—followed by ready-to-paste Swift code samples.

1. What Are Apple’s On-Device Foundation Models?

Apple ships two sibling LLMs: a device-scale model (~3 B params) embedded in Apple silicon and a server-scale mixture-of-experts model that runs inside Private Cloud Compute when more heft is required. ([machinelearning.apple.com][2]) The

Which GGUF is right for me? (Opinionated)

Good question! I am collecting human data on how quantization affects outputs. See here for more information: ggml-org/llama.cpp#5962

In the meantime, use the largest that fully fits in your GPU. If you can comfortably fit Q4_K_S, try using a model with more parameters.

High level instructions for getting GPT4All working on MacOS with LLaMACPP

See nomic-ai/gpt4all for canonical source.

Environment

• This walkthrough assumes you have created a folder called ~/GPT4All. Adjust the following commands as necessary for your own environment.
• It's highly advised that you have a sensible python virtual environment. A conda config is included below for simplicity. Install it with conda env create -f conda-macos-arm64.yaml and then use with conda activate gpt4all.
