Anthropic 新模型 Claude Fable 5.2 现在在 Arena.ai 上就能试，还开了 Agent Mode。有人拿它跑了 100 多次生成，跟 Opus 比 3D 场景、小游戏和 UI 生成，哪边强、哪边贵都讲了。想选模型写代码或做页面的开发者可以看看再决定。
Anthropic 的 Claude Fable 5.2 已上线 Arena.
ai，用户可在 Battle Mode 和 Agent Mode 两种模式下实际测试该模型的表现。测评者 @petergostev 用它跑了 100+ 次生成，并与 Claude Opus 做了直接对比。
测试覆盖五类任务：3D 世界构建、可玩小游戏、网站 UI、数据可视化和动画生成。从初步结论看，Fable 5.
2 在部分生成类任务上有提升，但 Opus 在某些场景仍有优势，两者的成本差异也是对比重点之一。对关注 Anthropic 模型迭代的开发者来说，这是一个可以直接上手验证的渠道。
