## AI 摘要

据推文透露，Claude 5 Fable（代号Fable）在几乎所有AI能力基准测试上达到SOTA，尤其在软件工程、知识工作、视觉、科学研究中表现优异。任务越长越复杂，其领先幅度越大；token效率高于以往Claude模型，能在百万token长任务中保持专注并自我优化输出。相比上一代Mythos有显著提升。实际案例：Stripe报告称Fable将数月工程压缩至数天，在5000万行Ruby代码库中一天完成代码库迁移（原需团队两月以上手工操作）。

## 正文

Claude 5 Fable tl；dr

- It is state-of-the-art on nearly all tested benchmarks of AI capability， showing exceptional performance in software engineering， knowledge work， vision， scientific research

-The longer and more complex the task， the larger Fable 5's lead over our other models

-its more token-efficient than past Claude models

- Fable 5 stays focused across millions of tokens in long-running tasks and improves its outputs using its own notes

Fable 5 is more than just better benchmarks. It's more efficient， allows for longer work periods， offers better context management， and so much more.

GPT-5.6 is just around the corner.

I'm a huge Codex fan， but Fable/Mythos is in a league of its own. I'm curious to see if OpenAI will release its own Mythos.

"During early testing， Stripe reported that Fable 5 compressed months of engineering into days. In a 50-million-line Ruby codebase， the model performed a codebase-wide migration in a day that would otherwise have taken a whole team over two months by hand."
