Brevox — Gemma 3 4B IT (ANE) Asset
Archived Core ML bundle used by Brevox as the on-device fallback summarizer when Apple FoundationModels rejects a given recording via its non-bypassable safety guardrails.
This repository only hosts the distribution artifact (the .aar file) for
the Brevox iOS/macOS app's runtime download. It is not the source of the
conversion pipeline nor a redistribution of upstream Google weights in their
original form.
What is this?
A single Apple Archive (.aar, LZFSE-compressed) containing a Core ML 3-stage
runner of Gemma 3 4B IT (int4 QAT, 4096 context) converted by
ANEMLL. Extracted at runtime into
~/Library/Application Support/Brevox/Models/Summarizer_Gemma3_4B/.

Why Hugging Face and not GitHub Releases
GitHub Releases caps individual asset size at 2 GB. The packaged bundle is 3.85 GB. Hugging Face's LFS-backed storage and anonymous CDN distribution are the appropriate hosting choice.
Usage (app side)
