## AI 摘要

Arena 按净提升分数与每任务中位成本对比各模型家族最强型号，家族按同一模型基名下的变体划分。GPT-6 Astra（Max）提升 +11.7%、$3.94/任务，Claude Fable 5.1（Max）+13.7%、$4.40/任务，两者性能相近却明显贵于各自实验室其他模型。

## 正文

We compared the top model from each family by net improvement score and median cost per task. Family is defined as variants within the same model base name.

GPT-6 Astra and Claude Fable 5.1 stand out: both cost far more than other models from their respective labs despite relatively close performance.

By @OpenAI:
• GPT-6 Astra (Max): +11.7% | $3.94/task
• GPT-5.6 Sol (xHigh): +7.0% | $1.03/task

By @AnthropicAI:
• Claude Fable 5.1 (Max): +13.7% | $4.40/task
• Claude Opus 5 (High): +10.2% | $2.07/task
