What this score means

On MATH-500, Phi-4 1.5B sits at #571 of 600. The leader, GPT-5.2 Max, scores 96.7, so the gap to the top is 49.1 points. The median model in this index scores 76.0, which puts Phi-4 1.5B below the midpoint.

Microsoft models average 64.4 on this benchmark. Phi-4 1.5B is 16.8 points below that provider line, so it is a weaker result than the average Microsoft model.

Among small open-weight models, the average is 53.7. Phi-4 1.5B is 6.1 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 47.6 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.
