Aria Reward Hacking 5K

A 5,000-row onboarding subset of gutenbergpbc/aria-reward-hacking, preserving exactly 25 rollouts from each of 200 RL training steps. It is intended for Gutenberg tutorials and inexpensive first analyses. The schema and stable sample_id values are unchanged from the 51,200-row source.

This is a Gutenberg reproduction artifact, not an official dataset release from the original authors. It contains model-generated code that may intentionally tamper with tests; do not execute that code outside a sandbox.

Load

from datasets import load_dataset
import json

dataset = load_dataset("gutenbergpbc/aria-reward-hacking-5k", split="train")
messages = json.loads(dataset[0]["messages"])

messages and message_spans remain JSON-encoded strings for portability.

Deterministic selection

The source contains 256 rows at each step. For every step, this subset selects the midpoint of each of 25 equal-width row-index strata:

row_index = floor((k + 0.5) * 256 / 25), for k = 0..24

Selected row indices: 5, 15, 25, 35, 46, 56, 66, 76, 87, 97, 107, 117, 128, 138, 148, 158, 168, 179, 189, 199, 209, 220, 230, 240, 250.

This spreads the sample across the full per-step batch instead of selecting only its first problem/generation groups. Selection is independent of labels and response content.

Dataset structure

The columns are identical to the source dataset:

sample_id, text, JSON-encoded messages, and JSON-encoded message_spans;
step, problem_id, and trainer score;
strict/loose reward-hacking and harmful-test-modification labels;
eq_correct, eq_hinted, is_in_grok_zone, and category_5way.

See the source dataset card for detailed field definitions and provenance.

Distribution

Statistic	Count
Rows	5,000
Training steps	200
Rows per step	25
Distinct problems	983
Strict reward hack	1,144
Loose reward hack	2,042
Harmful test modification	2,042
Correct	1,827
Hint detected	1,937

Five-way category counts are 1,061 clean correct, 766 correct with attempted reward hacking, 1,144 successful reward hacking, 132 failed reward-hacking attempts, and 1,897 incorrect without a loose reward-hacking attempt.

Intended use and limitations

This subset is suitable for product onboarding, workflow validation, broad training-trajectory analysis, and exploratory interpretability work. With only 25 rows per step, it is not suitable for precise per-step prevalence estimates. Rows are not IID, and training-step correlations are not causal evidence.

The upstream research repository did not declare a repository-level license when the source dataset was published. This derivative therefore retains the source dataset's other license designation.
