# Nawah-Math-Reasoning — Demo

A **51.8M-parameter** Arabic math reasoning model. It writes its derivation inside
`<think>…</think>` and then gives the final answer; the demo splits the two live as it streams —
the reasoning trace in one panel, the answer in the other.

Fine-tuned from [`oddadmix/50M-2048-Emhotob`](https://huggingface.co/oddadmix/50M-2048-Emhotob),
a Llama-architecture base pre-trained from scratch on ~20B Arabic tokens (12 layers, hidden 512,
2048 context).

> **بالعربية:** نموذج عربي صغير (~52 مليون معامل) يكتب خطوات تفكيره داخل وسم `<think>` ثم يعطي
> الإجابة النهائية. الديمو بيفصل الاتنين وانت بتتفرج على النموذج وهو بيكتب.

|---|---|
| 🧠 **Model** | [`oddadmix/Nawah-Math-Reasoning`](https://huggingface.co/oddadmix/Nawah-Math-Reasoning) |
| 🛠️ **Training code** | [`code/`](https://huggingface.co/oddadmix/Nawah-Math-Reasoning/tree/main/code) — data generation, translation, SFT, eval, GRPO |
| 📚 **Synthetic corpus** | [`oddadmix/arabic-math-reasoning-synth`](https://huggingface.co/datasets/oddadmix/arabic-math-reasoning-synth) — 120,462 arithmetically verified rows |
| 📚 **Translated corpus** | [`oddadmix/gsm8k-reasoning-ar`](https://huggingface.co/datasets/oddadmix/gsm8k-reasoning-ar) — 142,969 rows |

## Results

Number agreement, greedy decoding, on held-out splits. Every version of the model was scored on
identical rows, so the numbers are comparable across the whole development ladder.

| eval set | n | score |
|---|---:|---:|
| GSM8K-ar | 600 | **79.0%** |
| Arabic_Reasoning | 400 | **73.0%** |
| synthetic math | 1000 | **40.4%** |
| synthetic relational | 400 | **52.2%** |

The last row is what this release adds: problems where the difficulty is the *relation* between
quantities (`ضعف`, `نصف`, `أكثر بـ…`) rather than the arithmetic. The previous version scored
34.0% there — the relation appeared in barely 1.3% of the training corpus, so 20,139 rows were
generated specifically to fill the gap.

## Limitations

A 52M proof of concept. It reliably produces the *shape* of Arabic step-by-step reasoning, but
**arithmetic errors are the dominant failure mode** — the derivation is usually structurally
right, one computation is wrong, and the model then stays faithful to its own bad number. The
40.4% and 52.2% above are the honest ceiling on multi-step problems. Single-turn only; open-ended
and non-mathematical questions are out of distribution.

نموذج تجريبي: بيعرف يمشي خطوة خطوة بالعربي، بس بيغلط في الحساب كتير.

Runs on **ZeroGPU**. The model is small enough for CPU too — switch the Space to `cpu-basic` and
it still works, just slower.

## Configuration

| Variable | Purpose |
|---|---|
| `MODEL_ID` | Model repo to load (default `oddadmix/Nawah-Math-Reasoning`) |
| `MODEL_HF_TOKEN` | Only needed if `MODEL_ID` points at a **private** repo. (`HF_TOKEN` is reserved by Spaces and does not reach the container.) |
