Arabic LLM safety alignment studied using SFT, DPO, and guard calibration

A new study published on arXiv explores methods for improving safety alignment in Arabic large language models. Researchers evaluated supervised fine-tuning (SFT), direct preference optimization (DPO), and guard calibration techniques across five Arabic-capable models. The findings indicate that while refusal-only SFT can lead to overly broad refusals, specific mixed-SFT configurations can achieve high harmful-prompt refusal rates with acceptable benign refusal rates. DPO and inference guards showed varied effects across models, suggesting a need for model-specific optimization rather than a one-size-fits-all approach. The study also noted that improvements in Modern Standard Arabic did not fully transfer to Arabizi. AI
