## AI 摘要

版本号并不是理解现阶段模型能力提升的很有用的方式。不幸的是，这意味着如果你没有密切关注，会以为 5.4 相比 5 只是小幅提升，或者 4.6 相比 4 只是小幅提升。但事实并非如此。

## 正文

Version numbers are not a very useful way to understand model ability gains at this stage. Unfortunately that means that if you aren't following closely， you would expect that 5.4 is a small gain over 5， or 4.6 a small gain over 4. That just isn't the case， though.
