NuminaMath-CoT
Dataset Card for NuminaMath CoT
Dataset Summary
Approximately 860k math problems, where each solution is formatted in a Chain of Thought (CoT) manner. The sources of the dataset range from Chinese high school math exercises to US and international mathematics olympiad competition problems. The data were primarily collected from online exam paper PDFs and mathematics discussion forums. The processing steps include (a) OCR from the original PDFs, (b) segmentation… See the full description on the dataset page: https://huggingface.co/datasets/AI-MO/NuminaMath-CoT.NuminaMath-1.5
Dataset Card for NuminaMath 1.5

Dataset Card for NuminaMath-1.5-RL-Verifiable
Dataset Summary
NuminaMath-1.5-RL-Verifiable is a curated subset of the NuminaMath-1.5 dataset, specifically filtered to support reinforcement learning applications requiring verifiable outcomes. This collection consists of 131,063 math word problems from the original dataset that meet strict filtering criteria: all problems have definitive numerical answers, validated problem statements and solutions, and come from… See the full description on the dataset page: https://huggingface.co/datasets/nlile/NuminaMath-1.5-RL-Verifiable.NuminaMath-TIR
Dataset Card for NuminaMath CoT
Dataset Summary
Tool-integrated reasoning (TIR) plays a crucial role in this competition. However, collecting and annotating such data is both costly and time-consuming. To address this, we selected approximately 70k problems from the NuminaMath-CoT dataset, focusing on those with numerical outputs, most of which are integers. We then utilized a pipeline leveraging GPT-4 to generate TORA-like reasoning paths, executing the code and… See the full description on the dataset page: https://huggingface.co/datasets/AI-MO/NuminaMath-TIR.NuminaMath-LEAN-Sol
NuminaMath-LEAN Cleaned with NL Solutions
Dataset Summary
This is a cleaned version of the NuminaMath-LEAN dataset, enhanced with natural language (NL) solutions matched from source datasets. The primary goal is to provide paired formal statements/proofs with natural language solutions for proof formalization and theorem proving research.
The dataset matches problems from NuminaMath-LEAN with their corresponding natural language solutions from:
olympiads-ref: A… See the full description on the dataset page: https://huggingface.co/datasets/iiis-lean/NuminaMath-LEAN-Sol.NuminaMath-LEAN-Proof-Artifacts
NuminaMath-LEAN Proof Artifacts
Dataset Summary
This dataset provides proof-analysis artifacts derived from
AI-MO/NuminaMath-LEAN.
It is released with two aligned configs:
lite: dual-track proof validation/extraction artifacts
full: all lite fields plus dual-track main-theorem structural artifacts
Both configs are aligned by sample identity (uuid, original_index) and processing order.
Config Overview
Use lite for overall tactic usage statistics (e.g.… See the full description on the dataset page: https://huggingface.co/datasets/iiis-lean/NuminaMath-LEAN-Proof-Artifacts.NuminaMath-LEAN-satp-v4.27
NuminaMath-LEAN-satp-v4.27
Lean 4 formal-statement + initial proof goal_state pairs over the
NuminaMath-LEAN problem pool, packaged for Lean 4.27.0. This is the main
training set for SATP (Steering Aesop for Theorem Proving) running in a
Lean 4.27 environment.
Every row's formal_statement elaborates cleanly under the pinned toolchain
below, and every goal_state is the pretty-printed goal produced in that
row's own environment — the same rendering the SATP runtime observes at… See the full description on the dataset page: https://huggingface.co/datasets/ChristianZ97/NuminaMath-LEAN-satp-v4.27.NuminaMath-LEAN-satp-buffer-dspaug-Temp
NuminaMath-LEAN-satp-buffer-dspaug-Temp
Staging buffer for the DSP+ paper-augmentation sweep (2026-04-29). This
is a -Temp variant — lemma_names / lemma_scores are empty and
theorem_uuid is the join key (matches NuminaMath-LEAN-satp.uuid).
Retrieval population + rename-to-uuid happens at the
promote-to-canonical merge step, mirroring the precedent set by
NuminaMath-LEAN-satp-buffer-planf-v1-Temp.
