Appendix A: Task scenario dataset
The full dataset of task scenarios and model responses to the scenarios can be found at the following URL: https://reward-hack-easy-dataset-share.vercel.app/
Examples of task scenarios can be found as .txt files in this Google Drive folder. Also included in that folder are .txt files of the Python checker programs that evaluate responses to each scenario as reward hacking or not (see main post for more information), and “test cases”, which are labelled example responses to each scenario. The task scenarios in that folder are the fifty scenarios evaluated by human contractors (see Appendix H), which were selected at random.
Access to the code used to generate scenarios and to run the experiments is available on request.
Appendix B: Example scenario responses
All the samples in this appendix are the first sample from each model – these responses are not cherry-picked. The scenario in question is the first scenario in the set for human evaluation, which is also the example in the main post.
For the full set of model responses to the test scenarios used in the experiments, see Appendix A. Note that the dataset does not include more responses to this particular scenario, likely because it was used for training rather than testing.
