💥炸了:GPT-6 Astra 又把最难的数学评测打穿了!比Fable 5.1便宜8倍! MathArena 刚放出 8 月新榜:题目只收「上个月刚被推翻的猜想」,模型必须在 harness 里用工具硬刚 12 小时。 分点看 Astra的成绩: 🔹ArXivMath:88.60%,第 1(Fable 5.1 87.72%)
🔹BrokenArXiv:81.94%,第 1(Fable 5.1 79.76%) 🔹综合预期:89.8%,成本 $2.36/题
🔹对比 Fable high:$8.93;Fable max:$24.95
🔹6 月旧榜曾到 94% / 99%,新榜变难才掉分
🔹物理+CS 扩题:101/104,直接饱和
🔹答错会说「证不出」,不装懂 分数接近,账单差一个数量级。 来源:@j_dekoninck / http://matharena.ai 查看论文:https://matharena.ai/arxiv_august/ #GPT6Astra #MathArena #LLM #OpenAI #AIBenchmark
