serbeval: a Serbian-language LLM benchmark (official set v1.2)
Author: Djordje Markovic (@djolex999)
Code, task YAMLs, full leaderboard and methodology: https://github.com/djolex999/serbeval
serbeval tests what translated benchmarks cannot carry over into Serbian: case government, verbal aspect, the aorist and imperfect, sibilarization, numeral agreement, the ijekavian jat reflex, pravopis (together/apart, hyphenated compounds, prefixoids), č/ć, and Cyrillic/Latin consistency. It runs on lm-evaluation-harness 0.4.12.
This dataset is the official set v1.2: 351 items in 17 tasks.
v1.1 and v1.2 (2026-10-17) fixed gold answers and dropped 3 items; v1.2 checked every changed
gold against the text of Pravopis 2010 (tačka and page in the explanation). Both spellings are
accepted only where Pravopis 2010 and Klajn disagree. The history is under errata in
MANIFEST.json.
Verification
Every item has a status in MANIFEST.json:
| Status | Items | Meaning |
|---|---|---|
human |
61 | checked by a native speaker (blind baseline 29/30, plus the disputed items) |
consensus |
214 | fewer than 2 of the 4 strongest models disagreed with the gold |
derived |
76 | correction item built mechanically from an official item |
Model consensus is not human verification. It is labelled separately on purpose.
Gold answers come from three places:
- hand-written items;
- the srLex lexicon, using only forms attested in the corpus;
- source checks against Pravopis 2010 and Klajn.
Items where the authorities disagree (e.g. foto-aparat vs fotoaparat) were dropped rather than pinned to one side.

Three item shapes:
- MCQ:
question,choices(4),answer_index. Gold positions are balanced. - Cloze:
questionwith____,cue, andanswers, the list of every accepted form. Scoring folds case, outer punctuation and script, but never diacritics or an intra-word hyphen. - Correction:
text, which may contain one error;answers(the corrected sentence, or the text itself whenhas_erroris false). There is no cue.
All items also carry id, task, category, explanation, script, difficulty,
source, verified and license.

The frontier is near ceiling (GPT-6 Sol 99%, three more at 98%); its misses are mostly usage-over-norm spellings. Below it, the set separates models from 38% to 95%, and pravopis separates them most. The best open-weights model is DeepSeek V4 Pro (95%); turning reasoning on does not raise any tested model by more than 2 points. Details and caveats, including a possible small selection bias toward the four consensus models, are in the GitHub repo.
