# BayanSimplify-v0.2-Fast
Model 2 of the Bayan project, compact: AraBART on the same 22,733-pair mix, the app's fast default.
## What it does
The same data and tags as BayanSimplify-v0.2 on AraBART (139M parameters, a third of the size), so it fits a 250 MB
download as an int8 bundle (222 MB) and shows the first word on a mid-range phone in 82–172 ms.
**Input:** `بسط: ` (**without** the shadda, which AraBART's tokenizer cannot read), then an optional tag such as `[S2] `,
then the text.
**BayanBench v2.0, test, core items:**
| Setting | Meaning kept | Longest clause, words cut |
|---|---|---|
| `[S2]`, float | 40.1% | 6.7 |
| no tag, float | 51.4% | 4.9 |
| no tag, int8 in the app | 50.5% | 4.8 |
Fast, but it keeps the meaning less often than the AraT5v2 models; the app offers BayanSimplify-v0.3 as its large
model.
## Use
```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
repo = "Congi-libya/BayanSimplify-v0.2-Fast"
tok = AutoTokenizer.from_pretrained(repo)
model = AutoModelForSeq2SeqLM.from_pretrained(repo)
text = "وقد أدى التوسع العمراني السريع الذي شهدته المدينة خلال العقدين الماضيين إلى ازدحام مروري خانق في ساعات الذروة."
x = tok("بسط: " + text, return_tensors="pt", max_length=256, truncation=True)
y = model.generate(**x, num_beams=1, no_repeat_ngram_size=3, max_length=256)
print(tok.decode(y[0], skip_special_tokens=True))
```

## About Bayan
Bayan (بيان) simplifies Arabic text for readers with dyslexia, entirely on an Android phone: select text in any app,
choose «تبسيط» (Simplify), and a simpler version appears over the page. Built by Team Cogni for the Samsung Innovation
Campus AI capstone, 2026. Every number on this card comes from the team's final report and BayanBench v2.0, the
benchmark built for the task (meaning scored by Gemma 4 31B, checked against human raters, AUC 0.85).
