A meme calling out "benchmaxxing": models that look nearly identical on established benchmarks collapse when a fresh one drops — one falls from 89.4% to 19.1%, another from 88.8% to 33.3%, suggesting benchmark-tuned capabilities are overfitting rather than general skill. (The model version names are fictional, but the benchmark-gaming critique is a widespread community view.)
