Guides agents on preparing datasets, running parameter-efficient LoRA fine-tuning, and tracking telemetry metrics using the mlxtune CLI on Apple Silicon. Use when an agent wants to fine-tune standard Gemma 4 base models on text instructions.
Guides agents on preparing multimodal datasets in interleaved ChatML format, executing audio/vision fine-tuning with mlx-vlm, targeting specific layers, and performing key-sanitized weights fusion to avoid silent blank weights loading.
Guides agents on fine-tuning Gemma 4 Quantization-Aware Training (QAT) unquantized checkpoints, maintaining mathematical alignment during LoRA, and exporting to GGUF using strict q4_0 parameters to avoid post-training quantization drift on edge devices.

This skill provides step-by-step instructions for AI coding assistants and agents to compile, merge, and quantize fine-tuned Gemma models into highly optimized mobile runtimes (GGUF, LiteRT-LM, MLX Swift, and CoreML).
Before compilation, determine the best on-device runtime using the following decision patterns:
llama.cpp: Cross-platform (iOS, Android, Desktop). Supports hot-swapping multiple adapters. Runs on CPU/GPU.The repository includes a premium multi-format model compiler script scripts/export_formats.py that streamlines weight pipelines:
Fuse the base model and adapters dequantizing to 16-bit, copy vocab files, and quantize to GGUF in one command:
uv run scripts/export_formats.py gguf \
--base ./model \
--adapter ./adapters \
--dest ./my_model.gguf \
--outtype q4_k_m
Natively merges the LoRA adapter weights inside PyTorch and compiles them using litert-torch with highly optimized dynamic 8-bit quantization (dynamic_wi8_afp32):
uv run scripts/export_formats.py litert \
--base ./model \
--adapter ./adapters \
--dest ./models/litert
mlxtune fuse, pass --prefused ./fused_model_dequantized to bypass expensive on-the-fly PEFT reloading and save over 5GB of RAM overhead.Bakes adapters back and outputs a clean, MLX-compatible directory:
uv run scripts/export_formats.py mlx \
--base ./model \
--adapter ./adapters \
--dest ./models/mlx_model
When building local mobile applications that load these exported binaries, you must comply with strict Apple Sandbox policies:
FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask)). Apple preserves this directory but automatically excludes it from standard iCloud backups.
