# ChiShenMe BGE-M3 Recipe Dataset Packs

This repository contains offline recipe RAG dataset packs for the Android-first app **吃什么**.

The packs are generated from `recipe_corpus_full.json`, preprocessed into recipe chunks, and embedded with `BAAI/bge-m3` dense vectors.

## Variants

| Level | Chunks | Use case |
| --- | ---: | --- |
| Lite | 10,000 | Fast Android download and smoke tests |
| Medium | 100,000 | Beta testing and better recipe coverage |
| Full | 1,552,596 | Full offline recipe retrieval |

## Android Usage

The app downloads a `dataset-pack.json` file, then downloads the referenced files under `files/`.

Example manifest URL:

```text
https://huggingface.co/datasets/{username}/chishenme-datasets/resolve/main/chishenme-bge-m3-lite-10k/dataset-pack.json
```

Replace `{username}` with the actual Hugging Face namespace.

The Android ONNX query model pack is available at:

```text
https://huggingface.co/datasets/{username}/chishenme-datasets/resolve/main/models/bge-m3-query-onnx/model-pack.json
```

## Format

- `vectors.f32`: contiguous float32 dense vectors, row-major, normalized.
- `metadata.jsonl`: one JSON object per vector row.
- `embedding-manifest.json`: embedding generation metadata.
- `dataset-pack.json`: app-facing pack manifest with file sizes and SHA256 hashes.
- `model-pack.json`: app-facing ONNX query model manifest.
