About this data

High-quality RL training dataset combining math problems (NuminaMath-CoT) and coding problems (APPS, CodeContests, TACO, Codeforces) with outcome verifiers — LaTeX answers for math and test cases for code. ~450K examples, parquet, MIT-licensed.

Schema

Name	Type	Description
data_source	VARCHAR	Origin subset of the problem (e.g., numina_synthetic_math, APPS, CodeContests, TACO, Codeforces).
prompt	STRUCT("content" VARCHAR, "role" VARCHAR)[]	Array of message objects with 'content' (problem statement text) and 'role' (system/user/assistant) for multi-turn reasoning.
ability	VARCHAR	Capability category of the problem (e.g., math, code, reasoning).
reward_model	STRUCT(ground_truth VARCHAR, style VARCHAR)	Verifier configuration containing ground_truth (expected answer in LaTeX or reference solution) and style (verification method: rule, test, etc.).
extra_info	STRUCT("index" BIGINT, split VARCHAR)	Metadata struct with index (sequential problem identifier) and split (dataset partition: train/valid/test/dummy).
