Subclaims¶

q2 i? On completeness and method, Llama 3 70B appears to outperform GPT-4o because it tends to give positive evaluations (higher false positive rate) while GPT-4o is more rigorous (higher false negative rate); on the unit metric the pattern reverses, with Llama 3 70B performing significantly worse. → Liangliang Chen 2025

q2 · i? · design · r2

Error-pattern analysis of the benchmark responses. The article attributes Llama 3 70B's completeness/method advantage to leniency: it "tends to give positive eval- uations of students’ solutions, whereas GPT-4o is more rigorous," yielding a higher false positive rate for Llama 3 70B and a higher false negative rate for GPT-4o.

"In the metrics of completeness and method, Llama 3 70B appears to outperform GPT-4o. Detailed analysis shows that Llama 3 70B tends to give positive eval- uations of students’ solutions, whereas GPT-4o is more rigorous."
