-- [MATH and MATH-500](../../nemo_rl/data/eval_datasets/math.py)
-- [MMLU](../../nemo_rl/data/eval_datasets/mmlu.py): this also includes MMMLU (Multilingual MMLU), a total of 14 languages.
-- [MMLU-Pro](../../nemo_rl/data/eval_datasets/mmlu_pro.py)
+- [AIME-2024](../../nemo_rl/data/eval_datasets/aime2024.py): the corresponding `data.dataset_name` is `"aime2024"`.
+- [AIME-2025](../../nemo_rl/data/eval_datasets/aime2025.py): the corresponding `data.dataset_name` is `"aime2025"`.
+- [GPQA and GPQA-diamond](../../nemo_rl/data/eval_datasets/gpqa.py): the corresponding `data.dataset_name` are `"gpqa"` and `"gpqa-diamond"`.
+- [MATH and MATH-500](../../nemo_rl/data/eval_datasets/math.py): the corresponding `data.dataset_name` are `"math"` and `"math500"`.
+- [MMLU](../../nemo_rl/data/eval_datasets/mmlu.py): this also includes MMMLU (Multilingual MMLU), a total of 14 languages. When `data.dataset_name` is set to `mmlu`, the English version is used. If one wants to run evaluation on another language, `data.dataset_name` should be set to `mmlu_{language}` where `language` is one of following 14 values, `["AR-XY", "BN-BD", "DE-DE", "ES-LA", "FR-FR", "HI-IN", "ID-ID", "IT-IT", "JA-JP", "KO-KR", "PT-BR", "ZH-CN", "SW-KE", "YO-NG"]`.
+- [MMLU-Pro](../../nemo_rl/data/eval_datasets/mmlu_pro.py): the corresponding `data.dataset_name` is `"mmlu_pro"`.
