- To get these results, we used the Eleuther AI evaluation harness [here](https://github.com/EleutherAI/lm-evaluation-harness),

- which can produce results different than those reported in the GPT2 paper. The p-values come from the stderr from the evaluation harness, plus a normal distribution assumption.

91
+ To get these results, we used commit `f079e322b857714fcef1ada9e78ddc606fe51e84` of the Eleuther AI evaluation harness [here](https://github.com/EleutherAI/lm-evaluation-harness),
92
+ which can produce results different than those reported in the GPT2 paper.
93
+ We added a change [here](https://github.com/EleutherAI/lm-evaluation-harness/compare/master...mathemakitten:lm-evaluation-harness:master) to enable evaluation of the OLM GPT2, which has a very slightly different vocab size.
94
+ The p-values come from the stderr from the evaluation harness, plus a normal distribution assumption.
