Pith's one-line read Top LLMs answer just 30% of a new hard Arabic test
desk verdict A genuinely new Arabic evaluation set with a load-bearing reproducibility gap: the ADMD dataset is worth attention, but the model rankings are unverified until the data and scoring are released. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing object is the Arabic Depth Mini Dataset (ADMD), 490 questions organized into ten major domains and 42 sub-domains, each question sourced from an Arabic primary reference such as Tafsir Ibn Jarir al-Tabari, Lisan al-Arab, or Hindawi science books. The scoring procedure is the second mechanism: four researchers manually label each model response as True (100% correct), Partially-True (60–80%), Partially-False (20–30%), or False, and the same four-criteria rubric (Language Rules, Scientific Writing, Cultural Values, Information Correctness) is used to critique existing datasets like Ghafa, ArabicMMLU, and INCLUDE. The guidelines plus the dataset together form the argument: because the questions demand cultural depth instead of surface pattern matching, performance on ADMD measures something that MMLU-style benchmarks miss.
What would settle it
Have two independent teams of native Arabic experts score the same 490 model responses using the paper's four labels and compare their agreement; if agreement falls below standard reliability thresholds, the reported rankings (Claude 3.5 Sonnet 30%, GPT-4 11.8%) are not reproducible. A simpler check is to release the answer key and rerun the five models on ADMD to see whether the accuracy numbers match.
Extended reading notes
Core claim
On its own terms, the paper's central discovery is that expert-level Arabic cultural knowledge is almost entirely missing from current LLMs, and that this is hidden by existing benchmarks. Using the ADMD, Claude 3.5 Sonnet achieved the highest accuracy at 30% (147/490), with relative strengths in Mathematics & Computational Sciences (50%), Philosophy & Logic (50%), and General & Miscellaneous Sciences (51.67%), but near-total failure in Historical & Genealogical Studies (0%) and weak performance in Islamic & Religious Studies despite its relative lead. GPT-4 scored only 11.8% True, with the highest False rate. The paper reads these results as evidence that translated and automatically generated Arabic datasets produce misleadingly optimistic evaluations, and that culturally grounded, depth-oriented questions are needed to reveal actual model limitations.
Load-bearing premise
The entire model ranking rests on the authors' own manual judgments of what counts as True, Partially-True, Partially-False, or False, and those judgments have not been checked for inter-annotator agreement or made public as a full answer key.
Editorial extensions
If this is right
- If ADMD reflects genuine Arabic expert knowledge, then the frontier LLMs tested here are not yet dependable for Arabic cultural, religious, and specialist domains.
- Existing benchmarks such as ArabicMMLU and Ghafa can no longer be read as evidence of Arabic competence, since large fractions of their samples fail basic language and cultural checks.
- Model rankings are domain-dependent: Claude 3.5 Sonnet leads in mathematics and logic but still fails Islamic studies, so a single aggregate score hides practically meaningful differences.
- Future Arabic dataset builders should follow the proposed guidelines—primary-source attribution, cultural alignment, and evaluator expertise—or risk reproducing inflated results.
- Manual evaluation remains necessary for non-English tasks, since the paper cites evidence that LLM judges are unreliable for Arabic.
Reading between the lines
- If the ADMD answer key and scoring rubric were released with inter-annotator agreement numbers, the benchmark could serve as a reproducible stress test for Arabic NLP, but as published the headline scores cannot be independently verified.
- The 30% ceiling may partly reflect the strict True threshold (100% correct); a reader comparing these numbers with accuracy on MMLU-style benchmarks should treat them as different quantities, not the same measure applied to a harder test.
- A natural testable extension would be to measure whether Arabic fine-tuned models (e.g., Jais, Allam, Fanar, Aya) improve on ADMD without improving on translated benchmarks, which would isolate cultural knowledge from general reasoning.
- Because physics, chemistry, and advanced mathematics are excluded and medicine is thin, the domain ranking is a lower bound on the difficulty gap; adding those fields could shift the relative standings.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes a framework of theoretical guidelines for constructing Arabic evaluation datasets, audits three existing benchmarks (Ghafa, ArabicMMLU, INCLUDE) against those guidelines, and introduces a new 490-question Arabic Depth Mini Dataset (ADMD) spanning ten domains and 42 subdomains. Using ADMD, the authors manually scored outputs from five LLMs (GPT-4, Claude 3.5 Sonnet, Gemini Flash 1.5, CommandR 100B, Qwen-Max) into four categories (True, False, Partially-True, Partially-False). They report that Claude 3.5 Sonnet achieves the highest accuracy, with 147 correct answers (30%) and particular strength in Mathematics & Computational Sciences, Philosophy & Logic, and General & Miscellaneous Sciences, while all models struggle on culturally nuanced topics.
Significance. If the evaluation is reproducible, ADMD would be a useful culturally grounded Arabic evaluation resource, addressing a real gap in a field dominated by translated or surface-level benchmarks. The paper also makes a constructive contribution by articulating explicit linguistic, cultural, and methodological guidelines and by providing a structured comparison of existing datasets. However, the central empirical claim — the model ranking in Tables 7–11 and the 30% headline for Claude 3.5 Sonnet — currently rests on a non-public dataset, a manual grading process with no reported inter-annotator agreement, and internally inconsistent statements about whether an LLM judge was used. These issues make the headline results unverifiable as presented, so the significance of the contribution cannot yet be assessed.
major comments (4)
- [Abstract, §5.1, Table 5] The reported headline accuracy for Claude 3.5 Sonnet is internally inconsistent. The abstract and §5.1 state 147 questions (30%), but Table 5 reports the model's average True rate as 33.5%. The difference matters because categories have unequal sizes (most have 10 questions but General Linguistics and General Sciences have 50), so an unweighted category average can differ substantially from the overall percentage. The paper should state which quantity is reported, provide total counts for all models, and report the overall percentage alongside the category average. Without this clarification, the headline ranking is ambiguous.
- [§5, §5.1, Appendix A.2] The model rankings in Tables 7–11 depend entirely on the manual assignment of each model answer to True, False, Partially-True, or Partially-False, but the scoring process is not reproducible from the manuscript. The labels are defined only by broad percentage bands (60–80% correct, 20–30% correct) with no worked examples, no scoring rubric, no adjudication procedure, and no inter-annotator agreement measure. The full dataset and answer key are also not released; Appendix A.2 provides only sample examples via a link. To support the central claim, the authors should release the dataset with gold answers, provide the complete rubric, and report agreement statistics (e.g., Cohen's kappa) from at least two independent annotators on a representative sample.
- [§3.4, §5, footnote 4] The manuscript contradicts itself about whether an LLM judge was used. §3.4 states that the authors developed a Python library that leverages the Claude Sonnet model to automate dataset evaluation, and footnote 4 says that 'the most effective way to automate the evaluation is by using a judge LLM.' In contrast, §5 states that 'We did not use LLM Judge in this paper' and justifies manual evaluation. These statements cannot all be correct for the same evaluation pipeline. The authors need to clarify what the Claude-based library was used for (e.g., dataset construction, quality review, or final scoring) and state explicitly which stages used human annotators versus an LLM, since the reader's interpretation of Tables 7–11 changes accordingly.
- [§4, Tables 2–4] The review of existing datasets is based on a 'representative sample' manually evaluated by 'one of the authors' for each dataset, but no sample sizes, selection criteria, or scoring validation are reported. For example, Table 2 reports Ghafa's Language Rules score as 4.5 and Table 4 reports INCLUDE's Information Correctness as 7.0, yet without knowing how many items were sampled and how the scores were aggregated, these numbers cannot be verified or compared. Since these critiques motivate the need for ADMD, the authors should report the sampling procedure, the number of items reviewed per dataset, and ideally a second annotator for reliability.
minor comments (5)
- [Abstract] The phrase '(42 sub-domains, see Figure 1' is missing a closing parenthesis; it should read 'see Figure 1).'
- [§2 and §4.2] The paper alternately attributes ArabicMMLU to 'OpenAI (2024)' (in the Introduction and §4.2) and to Koto et al. (2024) in the Related Works and references. The citation should be unified to the correct source.
- [§4.1–§4.3] Several Arabic examples appear garbled in the rendered text (e.g., the Quranic verse example in §4.1 and the spelling-error examples in §4.3). Since the Arabic quality is a central claim, these excerpts must be typeset correctly.
- [Table 6] The caption 'first 10 rows per sheet, or 50 for long sheets' is unclear about the actual number of questions per subject; the text elsewhere says each topic has 10 questions except General Language and Diversified Science, which have 50, so the caption should state this directly.
- [§A.1] The reference list for ADMD sources is useful but incomplete: several entries give only URLs (e.g., the Dialects entries), and two entries appear as fragments ('Diwan al-Lugha al-'Arabiyya' and 'Hindawi Science Collection') without full bibliographic details.
Circularity Check
No circularity: the model rankings are independent manual measurements against a new dataset; self-citations are contextual and not load-bearing.
full rationale
The paper's central empirical claims are the accuracy measurements of five LLMs on the newly constructed ADMD dataset (Section 5.1, Tables 7-11). These claims are observational: model outputs were manually labeled True, False, Partially-True, or Partially-False using prose thresholds, not derived from any fitted parameter or defined equivalently to the benchmark's construction. No equation in the paper defines a predicted quantity in terms of the dataset's own inputs, and no model score is obtained by substituting a fitted constant back into the evaluation. The theoretical guidelines in Section 3 are said to be 'inspired by the work of (Nacar et al., 2025)', which involves overlapping authors, and Section 4 applies those guidelines to critique existing datasets; this is self-referential framing but it is not load-bearing for the headline accuracy result, because the ADMD measurements stand independently on the manual scoring of the questions. The inconsistencies noted by the reader, such as footnote 4 reporting that a judge LLM was found most effective while Section 5 states no LLM judge was used, and the difference between the abstract's 30% and Table 5's 33.5% average, are reproducibility and reporting concerns rather than circular derivations. There is no fitted-input-called-prediction step, no definitional identity between the evaluation framework and the model outputs, and no uniqueness or ansatz smuggled in via self-citation that forces the empirical rankings. Therefore the paper shows no significant circularity.

This paper addresses critical gaps in Arabic language model evaluation by establishing comprehensive theoretical guidelines and introducing a novel evaluation framework. We first analyze existing Arabic evaluation datasets, identifying significant issues in linguistic accuracy, cultural alignment, and methodological rigor. To address these limitations in LLMs, we present the Arabic Depth Mini Dataset (ADMD), a carefully curated collection of 490 challenging questions spanning ten major domains (42 sub-domains, see Figure 1. Using ADMD, we evaluate five leading language models: GPT-4, Claude 3.5 Sonnet, Gemini Flash 1.5, CommandR 100B, and Qwen-Max. Our results reveal significant variations in model performance across different domains, with particular challenges in areas requiring deep cultural understanding and specialized knowledge. Claude 3.5 Sonnet demonstrated the highest overall accuracy at 30\%, showing relative strength in mathematical theory in Arabic, Arabic language, and islamic domains. This work provides both theoretical foundations and practical insights for improving Arabic language model evaluation, emphasizing the importance of cultural competence alongside technical capabilities.
