THE WORKBENCH
One place for the model, the conversion, and the evidence. Inspect the work behind every response.
Pinned at the source. Every model snapshot has an exact revision.
Kept on your Mac. Weights, prompts, and results stay local.
Available to inspect. Open-source app. MIT licensed.
FROM CHECKPOINT TO CONVERSATION
Conversion is only the beginning. ANE Studio checks the output before you put the model to work.
Inspect Hugging Face metadata, pin a revision, and turn supported weights into a local Core ML package.
Source and Core ML logits must reach cosine similarity of at least 0.999 and choose the same top token. Failed parity blocks execution.
Chat locally and compare CPU, CPU+GPU, CPU+ANE, and automatic policies. Keep raw token timings and planned placement.
Current runtime: fixed 64-token context, recomputed each token. No KV cache yet. Architecture ↗
START SMALL
Development conversions tested on an Apple M5 Mac with 16 GB of memory. Each checkpoint earns its own pass.
Start here. A small hybrid convolution and attention model.
A larger checkpoint, tested through chat and policy comparison.
Historical development checks from 29 August 2026. These are conversion results, not a model-quality evaluation or a regression result for later adapters. Model licenses apply separately. Model support ↗
THE IMPORTANT DISTINCTION
Core ML can split a graph across devices or fall back. Selecting the Neural Engine does not prove it ran there.
Read the development results ↗The devices your compute policy permits.
Operation assignments from MLComputePlan.
An Instruments trace aligned with inference. Profile separately from timing.
MAKE IT YOUR EXPERIMENT

BEFORE YOU BEGIN
Built for experimentation.
Clear about its limits.
Model weights, prompts, converted packages, and results stay on your Mac. Hugging Face receives requests during metadata lookup and downloads. Chat and benchmarks run locally after preparation. Optional credentials use Electron safeStorage and macOS Keychain.
~/Library/Application Support/ANE Studio/
No. A checkpoint needs an explicit architecture adapter and a passing conversion. Unsupported architectures fail before weight downloads. The app does not load remote custom model code. The current fixed 64-token context is intended for short experiments.
Current builds are unsigned and not notarized. There is no public download linked here yet. Use the source setup, or check the repository for published releases and their installation instructions.
The ANE Studio app is MIT licensed. Downloaded models keep their own licenses and terms. Contributions and checkpoint-level evidence are welcome.
