OpenReasoning-RLVR-Balanced-GRPO

A cleaned and difficulty-scored conversion of Ksgk-fy/open-reasoning-rlvr-24k prepared for GRPO-style training.

Build

  • Source dataset: Ksgk-fy/open-reasoning-rlvr-24k
  • Source split: train
  • Allowed domains: math, science
  • Source rows processed: 24,000
  • Output examples: 16,000
  • Excluded-domain rows removed: 8,000
  • Empty problem rows removed: 0
  • Empty answer rows removed: 0
  • Uploaded shards: 5
  • Thinking-mode expansion: disabled — one output row per valid source problem

No reasoning field

Unlike some other OpenReasoning-derived datasets, the source dataset was built for RLVR (reward-verified RL) rather than distillation, so it carries no chain-of-thought / solution trace. There is therefore no reasoning column in this output — only problem, answer, and difficulty.

Domain filtering

The source dataset mixes three domains (math, science, code) with different verifiers. code rows carry an empty answer and are verified against tests (stdin/stdout pairs) instead, so they are excluded here. Only math and science rows are kept.

Difficulty labels

Each problem is scored with a heuristic classifier and grouped into one of 4 difficulty levels:

  • simple
  • medium
  • hard
  • extrem

For math rows, the score leans heavily on the source dataset's empirical pass_rate (fraction of rollouts that solved the problem) when available, combined with source provenance, question length, and text signals (multi-step reasoning, advanced-math terms, proof-heavy language). It should be treated as an annotation rather than ground-truth difficulty.

Removed rows

Rows are removed when:

  • domain is not one of math, science
  • question is empty or contains only whitespace
  • answer is empty or contains only whitespace

Output fields

problem

The problem presented to the model. (source: question)

answer

The normalized expected answer. (source: answer, unwrapped from \boxed{...} when present)

difficulty

One of:

simple, medium, hard, extrem

Intentionally removed fields

Only question and answer are kept from the source dataset (renamed to problem and answer). Every other source column — including id, domain, verifier, prompt, tests, and meta — is dropped from the output.

When thinking-mode expansion is enabled, the thinking mode is encoded directly into the problem field rather than stored as a separate column.

Processing

The source dataset is fully downloaded from Hugging Face before processing begins.

Data is converted and uploaded in chunks as JSONL shards.
