TranslateGemma-4B-Khutbah
Arabic → German translation model specialized for Islamic sermons (khutbahs) — the compact sibling of Yacinedh/translategemma-12b-khutbah. Fine-tuned from google/translategemma-4b-it.
Headline: after domain fine-tuning, this 4B matches the stock 12B on the khutbah benchmark at 40% of the size — making it a strong choice for CPU/edge deployment (e.g. an offline fallback on a mosque laptop).
Results
74-case khutbah benchmark (embedding cosine vs held-out references, identical pipeline for all rows):
| Model | Overall | Free sermon rhetoric |
|---|---|---|
| google/translategemma-4b-it (stock) | 0.9368 | 0.8588 |
| this model | 0.9527 | 0.8789 |
| google/translategemma-12b-it (stock, reference) | 0.9535 | 0.8836 |
Training
Same recipe and data as the 12B: 24,240 Arabic–German pairs (four German Quran editions, liturgical formulas, hadith, terminology; benchmark sentences excluded), QLoRA r=16, lr 1e-4, 1 epoch. Trained on a single T4 (fp16). Code: MinbarAI/training.
