Beyond Fluency: A Rubric-Based Benchmark for Evaluating Saudi Dialect and Cultural Competence in Large Language Models

The paper introduces a rubric-based benchmark to evaluate Saudi Arabic dialect and cultural competence in large language models. It comprises 31 expert-authored prompts covering idiomatic, pragmatic, lexical, and culturally embedded aspects, each paired with an expert-established ground truth. Four state-of-the-art models were scored, revealing that none exceeded 55% accuracy and that ambiguous framing was the most common error type.

HalluTruthQA: A Fine-Grained Benchmark for Hallucination Detection, Localization, and Explanation in Arabic Question Answering

Large language models (LLMs) can generate fluent Arabic answers, yet factual errors remain difficult to detect, localize, explain, and verify. Existing hallucination benchmarks often provide response-level labels, with limited support for identifying the exact erroneous content, explaining why it is incorrect, or selecting the correct factual answer.

Qistas: A Pre-Registered, Portable Protocol for Fairness Evaluation of Large Language Models

Qistas is a new protocol designed to evaluate how large language models treat the social, confessional, and regional constituencies of a society in a portable, pre‑registered manner. The pilot implementation focuses on Iraq and measures procedural symmetry, differential refusal, stereotype reliance, and terminological framing using paired statistical tests and a power analysis that specifies detectable effect sizes before data collection. The authors release an authoring apparatus—including a taxonomy, checklists, audit logs, and a human review notebook—and report a field test that uncovered several defect patterns common to counterfactual fairness benchmarks.
