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).

74-case khutbah benchmark (embedding cosine vs held-out references, identical pipeline for all rows):

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.

Identical to the 12B card — TranslateGemma structured chat template (source_lang_code: "ar", target_lang_code: "de-DE"). See Yacinedh/translategemma-12b-khutbah for snippets.
