Did Anthropic nerf Claude Opus 5.5? The first NerfBench results are live. We retested Opus 5.5 and GPT 6 Astra against their own launch scores. Claude Opus 5.5: 99.2% (-0.8% vs launch) GPT 6 Astra: 102.8% (+2.8% vs launch) Verdict: No nerf detected. Opus 5.5's small dip and GPT 6's small increase is within normal variance. More models and more frequent retests are coming. NerfBench only gets better as we collect more data. Which models should we retest next?
