Muna 161.8M Textbook Preview

This repository contains the adapted Muna checkpoint exported for the restricted textbook preview on Zeroth State. It is a real autoregressive model derived from Muna 161.8M Base. The website downloads the ONNX file after an explicit user action and runs inference on the visitor's device through WebGPU or browser CPU. It does not call a hosted generation API.

The adaptation improved its narrow textbook-grounded and structured-writing behavior. It did not pass the broader translation release gate, and it should not be used as an unrestricted assistant. The public preview enforces that boundary before inference.

Browser files

browser/muna-161m-browser-fp16.onnx: cache-aware FP16 ONNX export
tokenizer.model: Muna 32k SentencePiece Unigram tokenizer
config.json: architecture metadata
validation-fp16.json: recorded native-to-ONNX parity checks

The browser export passed 12 parity cases and an end-to-end generation smoke test before publication. Its current download size is 361 MB, so it is loaded only when a reader chooses to start the preview.

The untouched pretrained checkpoint is retained as a private Zeroth State research artifact.
