What this score means

On MATH-500, Pythia 8B sits at #595 of 600. The leader, GPT-5.2 Max, scores 96.7, so the gap to the top is 58.8 points. The median model in this index scores 76.0, which puts Pythia 8B below the midpoint.

EleutherAI models average 52.0 on this benchmark. Pythia 8B is 14.1 points below that provider line, so it is a weaker result than the average EleutherAI model.

Among small open-weight models, the average is 53.7. Pythia 8B is 15.8 points below that group. This is the more useful comparison if you are shortlisting within the same tier rather than across the whole index.

Read a 37.9 as a relative signal, not an absolute guarantee. Benchmark scores depend on prompt format, evaluation harness and contamination controls. Use this page to narrow the shortlist, then test the model on your own data.
